10.00--The Official Scorer. 10.01 OFFICIAL SCORER (GENERAL RULES) (a) The League President shall appoint an official scorer for each league championship, post-season or all-star game. The official scorer shall observe the game from a position in the press box. The official scorer shall have sole authority to make all

89


Rule 10.01 decisions concerning application of Rule 10 that involve judgment, such as whether a batter's advance to first base is the result of a hit or an error. The official scorer shall communicate such decisions to the press box and broadcasting booths by hand signals or over the press box loudspeaker system and shall advise the public address announcer of such decisions, if requested. The official scorer shall make all decisions concerning judgment calls within 24 hours after a game concludes or is suspended. A player or club may request that the League President review a judgment call of an official scorer made in a game in which such player or club participated, by notifying the League President in writing or by approved electronic means within 24 hours of the conclusion or suspension of such game, or within 24 hours of the official scorer's call, in the event the official scorer changes a call within 24 hours after a game concludes or is suspended, as provided in this Rule 10.01(a). The party requesting review shall submit, before the close of the second business day of the league office following the request for review, any written explanation or other evidence (such as videotapes or electronic media) the player or club wishes the League President to consider in reviewing such request. The League President shall not consider any evidence submitted after the time for submission set forth in this Rule 10.01(a). The League President, after considering the evidence submitted and any other evidence he wishes to consider, may request that the official scorer change a judgment call or, if the League President concludes that the judgment of the official scorer had been clearly erroneous, may order a change in a judgment call. No judgment decision shall be changed thereafter. A league may impose a reasonable fee upon a party requesting such review in the event that the judgment call of the official scorer being reviewed is upheld. After each game, including forfeited and called games, the official scorer shall prepare a report, on a form prescribed by the League President, listing the date of the game, where it was played, the names of the competing clubs and the umpires, the full score of the game and all records of individual players compiled according to the system specified in this Rule 10. The official scorer shall forward this report to the league office as soon as practicable after the game ends. The official scorer shall forward the report of any suspended game as soon as practicable after the game has

90


Rule 10.01 been completed, or after it becomes a called game because it cannot be completed, as provided by the Rule 4.12(b)(4).
Rule 10.01(a) Comment: The official scorer shall forward the official score report to the league statistician instead of to the league office, if requested to do so by the league. In the event of any discrepancy in records maintained by a league statistician and the rulings by an official scorer, the report of such official scorer shall control. League statisticians and official scorers should consult cooperatively to resolve any discrepancies. For the Major Leagues, the duties of a League President are carried out by one or more designees of the Commissioner of Baseball. See Rule 2.00 (League President) Comment.

(b)

(1) In all cases, the official scorer shall not make a scoring decision that is in conflict with Rule 10 or any other Official Baseball Rule. The official scorer shall conform strictly to the rules of scoring set forth in this Rule 10. The official scorer shall not make any decision that conflicts with an umpire's decision. The official scorer shall have authority to rule on any point not specifically covered in these rules. The League President shall order changed any decision of an official scorer that contradicts the rules of scoring set forth in this Rule 10 and shall take whatever remedial actions as may be necessary to correct any statistics that need correction as a result of such mistaken scoring decision. (2) If the teams change sides before three men are put out, the official scorer shall immediately inform the umpire-in-chief of the mistake. (3) If the game is protested or suspended, the official scorer shall make a note of the exact situation at the time of the protest or suspension, including the score, the number of outs, the position of any runners, the ball-and-strike count on the batter, the lineups of both teams and the players who have been removed from the game for each team.

Rule 10.01(b)(3) Comment: It is important that a suspended game resume with exactly the same situation as existed at the time of suspension. If a protested game is ordered replayed from the point of protest, the game must be resumed with exactly the situation that existed just before the protested play.

(4) The official scorer shall not call the attention of any umpire or of any member of either team to the fact that a player is batting out of turn.

91


Rule 10.01 to 10.02 (c) The official scorer is an official representative of the league, is entitled to the respect and dignity of his office and shall be accorded full protection by the League President. The official scorer shall report to the League President any indignity expressed by any manager, player, club employee or club officer in the course of, or as the result of, the discharge of official scorer duties.

10.02 OFFICIAL SCORE REPORT The official score report prepared by the official scorer shall be in a form prescribed by the league and shall include: (a) The following records for each batter and runner: (1) Number of times batted, except that no time at bat shall be charged when a player (i) hits a sacrifice bunt or sacrifice fly; (ii) is awarded first base on four called balls; (iii) is hit by a pitched ball; or (iv) is awarded first base because of interference or obstruction; (2) Number of runs scored; (3) Number of safe hits; (4) Number of runs batted in; (5) Two-base hits; (6) Three-base hits; (7) Home runs; (8) Total bases on safe hits; (9) Stolen bases; (10) Sacrifice bunts; (11) Sacrifice flies; (12) Total number of bases on balls; (13) Separate listing of any intentional bases on balls; (14) Number of times hit by a pitched ball; (15) Number of times awarded first base for interference or obstruction; (16) Strikeouts;

92


Rule 10.02 (17) Number of force double plays and reverse-force double plays grounded into; and

Rule 10.02(a)(17) Comment: The official scorer should not charge a batter with grounding into a double play if the batter-runner is called out due to interference by a preceding runner.

(18) (b)

Number of times caught stealing.

The following records for each fielder: (1) (2) (3) (4) (5) Number of putouts; Number of assists; Number of errors; Number of double plays participated in; and Number of triple plays participated in.

(c)

The following records for each pitcher: (1) Number of innings pitched;

Rule 10.02(c)(1) Comment: In computing innings pitched, the official scorer shall count each putout as  of an inning. For example, if a starting pitcher is replaced with one out in the sixth inning, the official scorer shall credit that pitcher with 5 innings. If a starting pitcher is replaced with none out in the sixth inning, the official scorer shall credit that pitcher with 5 innings and make the notation that that pitcher faced _____ batters in the sixth, noting the number of batters faced. If a relief pitcher retires two batters and is replaced, the official scorer shall credit that pitcher with  of an inning pitched. If a relief pitcher enters a game and his team initiates a successful appeal play that results in one out, the officer scorer shall credit such relief pitcher with  of an inning pitched.

(2) Total number of batters faced; (3) Number of batters officially at bat against pitcher, computed according to Rule 10.02(a)(1); (4) Number of hits allowed; (5) Number of runs allowed; (6) Number of earned runs allowed; (7) Number of home runs allowed; (8) Number of sacrifice hits allowed; (9) Number of sacrifice flies allowed;

93


Rule 10.02 (10) (11) (12) (13) (14) (15) (d) Total number of bases on balls allowed; Separate listing of any intentional bases on balls allowed; Number of batters hit by pitched balls; Number of strikeouts; Number of wild pitches; and Number of balks.

The following additional data: (1) (2) (3) (4) Name of the winning pitcher; Name of the losing pitcher; Names of the starting pitcher and the finishing pitcher for each team; and Name of pitcher credited with a save, if any.

(e) (f)

Number of passed balls allowed by each catcher. Name of players participating in double plays and triple plays.

Rule 10.02(f) Comment: For example, an official scorer would note: "Double Plays--Jones, Roberts and Smith (2). Triple Play--Jones and Smith."

(g)

Number of runners left on base by each team. This total shall include all runners who get on base by any means and who do not score and are not put out. The official scorer shall include in this total a batter-runner whose batted ball results in another runner being retired for the third out. Names of batters who hit home runs with the bases full. Number of outs when winning run scored, if the game was won in the last half-inning. The score by innings for each team. Names of umpires, listed in this order: plate umpire, first-base umpire, second-base umpire, third-base umpire, left-field umpire (if any) and right-field umpire (if any).

(h) (i)

(j) (k)

94


Rule 10.02 to 10.03

(l)

Time required to play the game, with delays deducted for weather, light failure or technological failure not related to game action.

Rule 10.02(l) Comment: A delay to attend to the injury of a player, manager, coach or umpire shall be counted in computing time of game.

(m)

Official attendance, as provided by the home club.

10.03 OFFICIAL SCORE REPORT (ADDITIONAL RULES) (a) In compiling the official score report, the official scorer shall list each player's name and fielding position, or positions, in the order in which the player batted, or would have batted if the game ended before the player came to bat.

Rule 10.03(a) Comment: When a player does not exchange positions with another fielder but is merely placed in a different spot for a particular batter (for example, if a second baseman goes to the outfield to form a four-man outfield, or if a third baseman moves to a position between the shortstop and second baseman), the official scorer should not list this as a new position.

(b)

The official scorer shall identify in the official score report any player who enters the game as a substitute batter or substitute runner, whether or not such player continues in the game thereafter, in the batting order by a special symbol that shall refer to a separate record of substitute batters and runners. The record of substitute batters shall describe what the substitute batter did. The record of substitute batters and runners shall include the name of any such substitute whose name is announced, but who is removed for another substitute before he actually gets into the game. Any such second substitute shall be recorded as batting or running for the first announced substitute.

Rule 10.03(b) Comment: Lower case letters are recommended as symbols for substitute batters and numerals are recommended as symbols for substitute runners. For example, an official score report may note as follows: "a-Singled for Abel in third inning; b-Flied out for Baker in sixth inning; c-Hit into force for Charles in seventh inning; d-Grounded out for Daniel in ninth inning; 1-Ran for Edward in ninth inning." If a substitute's name is announced but the substitute is removed for another substitute before he actually gets into the game, the official scorer report shall record the substitute, for example, as follows: "e-Announced as substitute for Frank in seventh inning."

95


Rule 10.03 (c) HOW TO PROVE A BOX SCORE. A box score shall balance (or is proven) when the total of the team's times at bat, bases on balls received, hit batters, sacrifice bunts, sacrifice flies and batters awarded first base because of interference or obstruction equals the total of that team's runs, players left on base and the opposing team's putouts. WHEN PLAYER BATS OUT OF TURN. When a player bats out of turn and is put out, and the proper batter is called out before the ball is pitched to the next batter, the official scorer shall charge the proper batter with a time at bat and score the putout and any assists the same as if the correct batting order had been followed. If an improper batter becomes a runner and the proper batter is called out for having missed his turn at bat, the official scorer shall charge the proper batter with a time at bat, credit the putout to the catcher and ignore everything entering into the improper batter's safe arrival on base. If more than one batter bats out of turn in succession, the official scorer shall score all plays just as they occur, skipping the turn at bat of the player or players who first missed batting in the proper order. CALLED AND FORFEITED GAMES. (1) If a regulation game is called, the official scorer shall include the record of all individual and team actions up to the moment the game ends, as defined in Rules 4.10 and 4.11. If the game is a tie game, the official scorer shall not enter a winning or losing pitcher. (2) If a regulation game is forfeited, the official scorer shall include the record of all individual and team actions up to the time of forfeit. If the winning team by forfeit is ahead at the time of forfeit, the official scorer shall enter as winning and losing pitchers the players who would have qualified as the winning and losing pitchers if the game had been called at the time of forfeit. If the winning team by forfeit is behind or if the score is tied at the time of forfeit, the official scorer shall not enter a winning or losing pitcher. If a game is forfeited before it becomes a regulation game, the official scorer shall include no records and shall report only the fact of the forfeit.

(d)

(e)

96


Rule 10.03 to 10.04
Rule 10.03(e) Comment: The official scorer shall not consider that, by rule, the score of a forfeited game is 9 to 0 (see Rule 2.00 (Forfeited Game)), notwithstanding the results on the field at the point the game is forfeited.

10.04 RUNS BATTED IN A run batted in is a statistic credited to a batter whose action at bat causes one or more runs to score, as set forth in this Rule 10.04. (a) The official scorer shall credit the batter with a run batted in for every run that scores (1) unaided by an error and as part of a play begun by the batter's safe hit (including the batter's home run), sacrifice bunt, sacrifice fly, infield out or fielder's choice, unless Rule 10.04(b) applies; (2) by reason of the batter becoming a runner with the bases full (because of a base on balls, an award of first base for being touched by a pitched ball or for interference or obstruction); or (3) when, before two are out, an error is made on a play on which a runner from third base ordinarily would score. (b) The official scorer shall not credit a run batted in (1) when the batter grounds into a force double play or a reverse-force double play; or (2) when a fielder is charged with an error because the fielder muffs a throw at first base that would have completed a force double play. (c) The official scorer's judgment must determine whether a run batted in shall be credited for a run that scores when a fielder holds the ball or throws to a wrong base. Ordinarily, if the runner keeps going, the official scorer should credit a run batted in; if the runner stops and takes off again when the runner notices the misplay, the official scorer should credit the run as scored on a fielder's choice.

97


Rule 10.05 10.05 BASE HITS A base hit is a statistic credited to a batter when such batter reaches base safely, as set forth in this Rule 10.05. (a) The official scorer shall credit a batter with a base hit when: (1) the batter reaches first base (or any succeeding base) safely on a fair ball that settles on the ground, that touches a fence before being touched by a fielder or that clears a fence; (2) the batter reaches first base safely on a fair ball hit with such force, or so slowly, that any fielder attempting to make a play with the ball has no opportunity to do so;
Rule 10.05(a)(2) Comment: The official scorer shall credit a hit if the fielder attempting to handle the ball cannot make a play, even if such fielder deflects the ball from or cuts off another fielder who could have put out a runner.

(3) the batter reaches first base safely on a fair ball that takes an unnatural bounce so that a fielder cannot handle it with ordinary effort, or that touches the pitcher's plate or any base (including home plate) before being touched by a fielder and bounces so that a fielder cannot handle the ball with ordinary effort; (4) the batter reaches first base safely on a fair ball that has not been touched by a fielder and that is in fair territory when the ball reaches the outfield, unless in the scorer's judgment the ball could have been handled with ordinary effort; (5) a fair ball that has not been touched by a fielder touches a runner or an umpire, unless a runner is called out for having been touched by an Infield Fly, in which case the official scorer shall not score a hit; or (6) a fielder unsuccessfully attempts to put out a preceding runner and, in the official scorer's judgment, the batter-runner would not have been put out at first base by ordinary effort.

98


Rule 10.05 to 10.06
Rule 10.05(a) Comment: In applying Rule 10.05(a), the official scorer shall always give the batter the benefit of the doubt. A safe course for the official scorer to follow is to score a hit when exceptionally good fielding of a ball fails to result in a putout.

(b)

The official scorer shall not credit a base hit when a: (1) runner is forced out by a batted ball, or would have been forced out except for a fielding error; (2) batter apparently hits safely and a runner who is forced to advance by reason of the batter becoming a runner fails to touch the first base to which such runner is advancing and is called out on appeal. The official scorer shall charge the batter with a time at bat but no hit; (3) pitcher, the catcher or any infielder handles a batted ball and puts out a preceding runner who is attempting to advance one base or to return to his original base, or would have put out such runner with ordinary effort except for a fielding error. The official scorer shall charge the batter with a time at bat but no hit; (4) fielder fails in an attempt to put out a preceding runner and, in the scorer's judgment, the batter-runner could have been put out at first base; or

Rule 10.05(b) Comment: Rule 10.05(b) shall not apply if the fielder merely looks toward or feints toward another base before attempting to make the putout at first base.

(5) runner is called out for interference with a fielder attempting to field a batted ball, unless in the scorer's judgment the batter-runner would have been safe had the interference not occurred. 10.06 DETERMINING VALUE OF BASE HITS The official scorer shall score a base hit as a one-base hit, two-base hit, three-base hit or home run when no error or putout results, as follows:

99


Rule 10.06 (a) Subject to the provisions of Rules 10.06(b) and 10.06(c), it is a one-base hit if the batter stops at first base; it is a two-base hit if the batter stops at second base; it a three-base hit if the batter stops at third base; and it is a home run if the batter touches all bases and scores. When, with one or more runners on base, the batter advances more than one base on a safe hit and the defensive team makes an attempt to put out a preceding runner, the scorer shall determine whether the batter made a legitimate two-base hit or three-base hit, or whether the batter-runner advanced beyond first base on the fielder's choice.

(b)

Rule 10.06 Comment: The official scorer shall not credit the batter with a three-base hit when a preceding runner is put out at home plate, or would have been out but for an error. The official scorer shall not credit the batter with a two-base hit when a preceding runner trying to advance from first base is put out at third base, or would have been out but for an error. The official scorer shall not, however, with the exception of the above, determine the value of base-hits by the number of bases advanced by a preceding runner. A batter may deserve a two-base hit even though a preceding runner advances one or no bases; a batter may deserve only a one-base hit even though he reaches second base and a preceding runner advances two bases. For example: (1) Runner on first. Batter hits to right fielder, who throws to third base in an unsuccessful attempt to put out runner. Batter takes second base. The official scorer shall credit batter with one-base hit. (2) Runner on second. Batter hits fair fly ball. Runner holds up to determine if ball is caught and then advances only to third base, while batter takes second base. The official scorer shall credit batter with two-base hit. (3) Runner on third. Batter hits high, fair fly. Runner takes a lead, then runs back to tag up, thinking the ball will be caught. The ball falls safe, but runner cannot score, although batter has reached second. The official scorer shall credit batter with a two-base hit.

(c)

When the batter attempts to make a two-base hit or a three-base hit by sliding, he must hold the last base to which he advances. If a batter-runner overslides and is tagged out before getting back to the base safely, he shall be credited with only as many bases as he attained safely. If a batter-runner overslides second base and is tagged out, the official scorer shall credited him with a one-base hit; if the batterrunner overslides third base and is tagged out, the official scorer shall credit him with a two-base hit.

Rule 10.06(c) Comment: If the batter-runner overruns second or third base and is tagged out trying to return, the official scorer shall credit the batter-runner with the last base he touched. If a batter-runner runs past second base after reaching that base on his feet, attempts to return and is tagged out, the official scorer shall credit the batter with a two-base hit. If a batter-runner runs past third base after reaching that

100


Rule 10.06
base on his feet, attempts to return and is tagged out, the official scorer shall credit the batter with a three-base hit.

(d)

When the batter, after making a safe hit, is called out for having failed to touch a base, the last base the batter reached safely shall determine if the official scorer shall credit him with a one-base hit, a two-base hit or a three-base hit. If a batter-runner is called out after missing home plate, the official scorer shall credit him with a three-base hit. If a batter-runner is called out for missing third base, the official scorer shall credit him with a two-base hit. If a batter-runner is called out for missing second base, the official scorer shall credit him with a one-base hit. If a batter-runner is called out for missing first base, the official scorer shall charge him with a time at bat, but no hit. When a batter-runner is awarded two bases, three bases or a home run under the provisions of Rules 7.05 or 7.06(a), the official scorer shall credit the batter-runner with a two-base hit, a three-base hit or a home run, as the case may be. Subject to the provisions of Rule 10.06(g), when a batter ends a game with a safe hit that drives in as many runs as are necessary to put his team in the lead, the official scorer shall credit such batter with only as many bases on his hit as are advanced by the runner who scores the winning run, and then only if the batter runs out his hit for as many bases as are advanced by the runner who scores the winning run.

(e)

(f)

Rule 10.06(f) Comment: The official scorer shall apply this rule even when the batter is theoretically entitled to more bases because of being awarded an "automatic" extra-base hit under various provisions of Rules 6.09 and 7.05. The official scorer shall credit the batter with a base touched in the natural course of play, even if the winning run has scored moments before on the same play. For example, the score is tied in the bottom of the ninth inning with a runner on second base and the batter hits a ball to the outfield that falls for a base hit. The runner scores after the batter has touched first base and continued on to second base but shortly before the batter-runner reaches second base. If the batter-runner reaches second base, the official scorer shall credit the batter with a two-base hit.

(g)

When the batter ends a game with a home run hit out of the playing field, the batter and any runners on base are entitled to score.

101


Rule 10.07 10.07 STOLEN BASES AND CAUGHT STEALING The official scorer shall credit a stolen base to a runner whenever the runner advances one base unaided by a hit, a putout, an error, a force-out, a fielder's choice, a passed ball, a wild pitch or a balk, subject to the following: (a) When a runner starts for the next base before the pitcher delivers the ball and the pitch results in what ordinarily is scored a wild pitch or passed ball, the official scorer shall credit the runner with a stolen base and shall not charge the misplay, unless, as a result of the misplay, the stealing runner advances an extra base, or another runner also advances, in which case the official scorer shall score the wild pitch or passed ball as well as the stolen base. When a runner is attempting to steal, and the catcher, after receiving the pitch, makes a wild throw trying to prevent the stolen base, the official scorer shall credit the runner with a stolen base. The official scorer shall not charge an error unless the wild throw permits the stealing runner to advance one or more extra bases, or permits another runner to advance, in which case the official scorer shall credit the runner with the stolen base and charge one error to the catcher. When a runner, attempting to steal, or after being picked off base, evades being put out in a run-down play and advances to the next base without the aid of an error, the official scorer shall credit the runner with a stolen base. If another runner also advances on the play, the official scorer shall credit both runners with stolen bases. If a runner advances while another runner, attempting to steal, evades being put out in a run-down play and returns safely, without the aid of an error, to the base he originally occupied, the official scorer shall credit a stolen base to the runner who advances. When a double- or triple-steal is attempted and one runner is thrown out before reaching and holding the base such runner is attempting to steal, no other runner shall be credited with a stolen base.

(b)

(c)

(d)

102


Rule 10.07 (e) When a runner is tagged out after oversliding a base, while attempting either to return to that base or to advance to the next base, the official scorer shall not credit such runner with a stolen base. When in the scorer's judgment a runner attempting to steal is safe because of a muffed throw, the official scorer shall not credit a stolen base. The official scorer shall credit an assist to the fielder who made the throw, charge an error to the fielder who muffed the throw and charge the runner with "caught stealing." The official scorer shall not score a stolen base when a runner advances solely because of the defensive team's indifference to the runner's advance. The official scorer shall score such a play as a fielder's choice.

(f)

(g)

Rule 10.07(g) Comment: The scorer shall consider, in judging whether the defensive team has been indifferent to a runner's advance, the totality of the circumstances, including the inning and score of the game, whether the defensive team had held the runner on base, whether the pitcher had made any pickoff attempts on that runner before the runner's advance, whether the fielder ordinarily expected to cover the base to which the runner advanced made a move to cover such base, whether the defensive team had a legitimate strategic motive to not contest the runner's advance or whether the defensive team might be trying impermissibly to deny the runner credit for a stolen base. For example, with runners on first and third bases, the official scorer should ordinarily credit a stolen base when the runner on first advances to second, if, in the scorer's judgment, the defensive team had a legitimate strategic motive-- namely, preventing the runner on third base from scoring on the throw to second base--not to contest the runner's advance to second base. The official scorer may conclude that the defensive team is impermissibly trying to deny a runner credit for a stolen base if, for example, the defensive team fails to defend the advance of a runner approaching a league or career record or a league statistical title.

(h)

The official scorer shall charge a runner as "caught stealing" if such runner is put out, or would have been put out by errorless play, when such runner (1) tries to steal; (2) is picked off a base and tries to advance (any move toward the next base shall be considered an attempt to advance); or (3) overslides while stealing.

Rule 10.07(h) Comment: In those instances where a pitched ball eludes the catcher and the runner is put out trying to advance, the official scorer shall not charge any "caught stealing." The official scorer shall not charge any caught stealing when a runner is awarded a base due to obstruction or when a runner

103


Rule 10.07 to 10.08
is called out due to interference by the batter. The official scorer shall not charge a runner with a caught stealing if such runner would not have been credited with a stolen base had such runner been safe (for example, when a catcher throws the runner out after such runner tries to advance after a ball that had eluded the catcher on a pitch).

10.08 SACRIFICES The official scorer shall: (a) Score a sacrifice bunt when, before two are out, the batter advances one or more runners with a bunt and is put out at first base, or would have been put out except for a fielding error, unless, in the judgment of the official scorer, the batter was bunting exclusively for a base hit and not sacrificing his own chance of reaching first base for the purpose of advancing a runner or runners, in which case the official scorer shall charge the batter with a time at bat;

Rule 10.08(a) Comment: In determining whether the batter had been sacrificing his own chance of reaching first base for the purpose of advancing a runner, the official scorer shall give the batter the benefit of the doubt. The official scorer shall consider the totality of the circumstances of the at-bat, including the inning, the number of outs and the score.

(b)

Score a sacrifice bunt when, before two are out, the fielders handle a bunted ball without error in an unsuccessful attempt to put out a preceding runner advancing one base, unless, an attempt to turn a bunt into a putout of a preceding runner fails, and in the judgment of the official scorer ordinary effort would not have put out the batter at first base, in which case the batter shall be credited with a one-base hit and not a sacrifice; Not score a sacrifice bunt when any runner is put out attempting to advance one base on a bunt, in which case the official scorer shall charge the batter with a time at bat; and Score a sacrifice fly when, before two are out, the batter hits a ball in flight handled by an outfielder or an infielder running in the outfield in fair or foul territory that (1) is caught, and a runner scores after the catch, or

(c)

(d)

104


Rule 10.08 to 10.09 (2) is dropped, and a runner scores, if in the scorer's judgment the runner could have scored after the catch had the fly been caught.
Rule 10.08(d) Comment: The official scorer shall score a sacrifice fly in accordance with Rule 10.08(d)(2) even though another runner is forced out by reason of the batter becoming a runner.

10.09 PUTOUTS A putout is a statistic credited to a fielder whose action causes the out of a batterrunner or runner, as set forth in this Rule 10.09. (a) The official scorer shall credit a putout to each fielder who (1) catches a ball that is in flight, whether fair or foul; (2) catches a batted or thrown ball and tags a base to put out a batter or runner; or
Rule 10.09(a)(2) Comment: The official scorer shall credit a fielder with a putout if such fielder catches a thrown ball and tags a base to record an out on an appeal play.

(3) tags a runner when the runner is off the base to which the runner is entitled. (b) The official scorer shall credit an automatic putout to the catcher when a: (1) batter is called out on strikes; (2) batter is called out for an illegally batted ball; (3) batter is called out for bunting foul for his third strike;
Rule 10.09(b)(3) Comment: Note the exception in Rule 10.15(a)(4).

(4) batter is called out for being touched by his own batted ball; (5) batter is called out for interfering with the catcher;

105


Rule 10.09 (6) batter is called out for failing to bat in his proper turn;
Rule 10.09(b)(6) Comment: See Rule 10.03(d).

(7) batter is called out for refusing to touch first base after receiving a base on balls, after being hit by a pitch or after a catcher's interference ; or (8) runner is called out for refusing to advance from third base to home plate. (c) The official scorer shall credit automatic putouts as follows (and shall credit no assists on these plays except as specified): (1) When the batter is called out on an Infield Fly that is not caught, the official scorer shall credit the putout to the fielder who the scorer believes could have made the catch; (2) When a runner is called out for being touched by a fair ball (including an Infield Fly), the official scorer shall credit the putout to the fielder nearest the ball; (3) When a runner is called out for running out of line to avoid being tagged, the official scorer shall credit the putout to the fielder whom the runner avoided; (4) When a runner is called out for passing another runner, the official scorer shall credit the putout to the fielder nearest the point of passing; (5) When a runner is called out for running the bases in reverse order, the official scorer shall credit the putout to the fielder covering the base the runner left in starting his reverse run; (6) When a runner is called out for having interfered with a fielder, the official scorer shall credit the putout to the fielder with whom the runner interfered, unless the fielder was in the act of throwing the ball when the interference occurred, in which case the official scorer shall credit the putout to the fielder

106


Rule 10.09 to 10.10 for whom the throw was intended and shall credit an assist to the fielder whose throw was interfered with; or (7) When the batter-runner is called out because of interference by a preceding runner, as provided in Rule 6.05(m), the official scorer shall credit the putout to the first baseman. If the fielder interfered with was in the act of throwing the ball, the official scorer shall credit such fielder with an assist but shall credit only one assist on any one play under the provisions of Rule 10.09(c)(6) and 10.09(c)(7). 10.10 ASSISTS An assist is a statistic credited to a fielder whose action contributes to a batter-runner or runner being put out, as set forth in this Rule 10.10. (a) The official scorer shall credit an assist to each fielder who (1) throws or deflects a batted or thrown ball in such a way that a putout results, or would have resulted except for a subsequent error by any fielder. Only one assist and no more shall be credited to each fielder who throws or deflects the ball in a run-down play that results in a putout, or would have resulted in a putout, except for a subsequent error; or
Rule 10.10(a)(1) Comment: Mere ineffective contact with the ball shall not be considered an assist. "Deflect" shall mean to slow down or change the direction of the ball and thereby effectively assist in putting out a batter or runner. If a putout results from an appeal play within the natural course of play, the official scorer shall give assists to each fielder, except the fielder making the putout, whose action led to the putout. If a putout results from an appeal play initiated by the pitcher throwing to a fielder after the previous play has ended, the official scorer shall credit the pitcher, and only the pitcher, with an assist.

(2) throws or deflects the ball during a play that results in a runner being called out for interference or for running out of line. (b) The official scorer shall not credit an assist to (1) the pitcher on a strikeout, unless the pitcher fields an uncaught third strike and makes a throw that results in a putout;

107


Rule 10.10 to 10.12

(2) the pitcher when, as the result of a legal pitch received by the catcher, a runner is put out, as when the catcher picks a runner off base, throws out a runner trying to steal or tags a runner trying to score; or (3) a fielder whose wild throw permits a runner to advance, even though the runner subsequently is put out as a result of continuous play. A play that follows a misplay (whether or not the misplay is an error) is a new play, and the fielder making any misplay shall not be credited with an assist unless such fielder takes part in the new play. 10.11 DOUBLE AND TRIPLE PLAYS The official scorer shall credit participation in a double play or triple play to each fielder who earns a putout or an assist when two or three players are put out between the time a pitch is delivered and the time the ball next becomes dead or is next in possession of the pitcher in a pitching position, unless an error or misplay intervenes between putouts.
Rule 10.11 Comment: The official scorer shall credit a double play or triple play also if an appeal play after the ball is in possession of the pitcher results in an additional putout.

10.12 ERRORS An error is a statistic charged against a fielder whose action has assisted the team on offense, as set forth in this Rule 10.12. (a) The official scorer shall charge an error against any fielder: (1) whose misplay (fumble, muff or wild throw) prolongs the time at bat of a batter, prolongs the presence on the bases of a runner or permits a runner to advance one or more bases, unless, in the judgment of the official scorer, such fielder deliberately permits a foul fly to fall safe with a runner on third base before two are out in order that the runner on third shall not score after the catch;

108


Rule 10.12
Rule 10.12(a)(1) Comment: Slow handling of the ball that does not involve mechanical misplay shall not be construed as an error. For example, the official scorer shall not charge a fielder with an error if such fielder fields a ground ball cleanly but does not throw to first base in time to retire the batter. It is not necessary that the fielder touch the ball to be charged with an error. If a ground ball goes through a fielder's legs or a fly ball falls untouched and, in the scorer's judgment, the fielder could have handled the ball with ordinary effort, the official scorer shall charge such fielder with an error. For example, the official scorer shall charge an infielder with an error when a ground ball passes to either side of such infielder if, in the official scorer's judgment, a fielder at that position making ordinary effort would have fielded such ground ball and retired a runner. The official scorer shall charge an outfielder with an error if such outfielder allows a fly ball to drop to the ground if, in the official scorer's judgment, an outfielder at that position making ordinary effort would have caught such fly ball. If a throw is low, wide or high, or strikes the ground, and a runner reaches base who otherwise would have been put out by such throw, the official scorer shall charge the player making the throw with an error. The official scorer shall not score mental mistakes or misjudgments as errors unless a specific rule prescribes otherwise. A fielder's mental mistake that leads to a physical misplay--such as throwing the ball into the stands or rolling the ball to the pitcher's mound, mistakenly believing there to be three outs, and thereby allowing a runner or runners to advance--shall not be considered a mental mistake for purposes of this rule and the official scorer shall charge a fielder committing such a mistake with an error. The official scorer shall not charge an error if the pitcher fails to cover first base on a play, thereby allowing a batter-runner to reach first base safely. The official scorer shall not charge an error to a fielder who incorrectly throws to the wrong base on a play. The official scorer shall charge an error to a fielder who causes another fielder to misplay a ball-- for example, by knocking the ball out of the other fielder's glove. On such a play, when the official scorer charges an error to the interfering fielder, the official scorer shall not charge an error to the fielder with whom the other fielder interfered.

(2) when such fielder muffs a foul fly to prolong the time at bat of a batter, whether the batter subsequently reaches first base or is put out; (3) when such fielder catches a thrown ball or a ground ball in time to put out the batter-runner and fails to tag first base or the batter-runner; (4) when such fielder catches a thrown ball or a ground ball in time to put out any runner on a force play and fails to tag the base or the runner; (5) whose wild throw permits a runner to reach a base safely, when in the scorer's judgment a good throw would have put out the runner, unless such wild throw is made attempting to prevent a stolen base; (6) whose wild throw in attempting to prevent a runner's advance permits that runner or any other runner to advance one or more bases beyond the base such runner would have reached had the throw not been wild;

109


Rule 10.12 (7) whose throw takes an unnatural bounce, touches a base or the pitcher's plate, or touches a runner, a fielder or an umpire, thereby permitting any runner to advance; or
Rule 10.12(a)(7) Comment: The official scorer shall apply this rule even when it appears to be an injustice to a fielder whose throw was accurate. For example, the official scorer shall charge an error to an outfielder whose accurate throw to second base hits the base and caroms back into the outfield, thereby permitting a runner or runners to advance, because every base advanced by a runner must be accounted for.

(8) whose failure to stop, or try to stop, an accurately thrown ball permits a runner to advance, so long as there was occasion for the throw. If such throw was made to second base, the official scorer shall determine whether it was the duty of the second baseman or the shortstop to stop the ball and shall charge an error to the negligent fielder.
Rule 10.12(a)(8) Comment: If, in the official scorer's judgment, there was no occasion for the throw, the official scorer shall charge an error to the fielder who threw the ball.

(b)

The official scorer shall charge only one error on any wild throw, regardless of the number of bases advanced by one or more runners. When an umpire awards the batter or any runner or runners one or more bases because of interference or obstruction, the official scorer shall charge the fielder who committed the interference or obstruction with one error, no matter how many bases the batter, or runner or runners, may advance.

(c)

Rule 10.12(c) Comment: The official scorer shall not charge an error if obstruction does not change the play, in the opinion of the scorer.

(d)

The official scorer shall not charge an error against: (1) the catcher when the catcher, after receiving the pitch, makes a wild throw attempting to prevent a stolen base, unless the wild throw permits the stealing runner to advance one or more extra bases or permits any other runner to advance one or more bases;

110


Rule 10.12 (2) any fielder who makes a wild throw if in the scorer's judgment the runner would not have been put out with ordinary effort by a good throw, unless such wild throw permits any runner to advance beyond the base he would have reached had the throw not been wild; (3) any fielder who makes a wild throw in attempting to complete a double play or triple play, unless such wild throw enables any runner to advance beyond the base such runner would have reached had the throw not been wild;
Rule 10.12(d) Comment: When a fielder muffs a thrown ball that, if held, would have completed a double play or triple play, the official scorer shall charge an error to the fielder who drops the ball and credit an assist to the fielder who made the throw.

(4) any fielder when, after fumbling a ground ball or dropping a batted ball that is in flight or a thrown ball, the fielder recovers the ball in time to force out a runner at any base; or (5) any fielder when a wild pitch or passed ball is scored. (e) The official scorer shall not charge an error when the batter is awarded first base on four called balls, when the batter is awarded first base when touched by a pitched ball, or when the batter reaches first base as the result of a wild pitch or passed ball.

Rule 10.12(e) Comment: See Rule 10.13 for additional scoring rules relating to wild pitches and passed balls.

(f)

The official scorer shall not charge an error when a runner or runners advance as the result of a passed ball, a wild pitch or a balk. (1) When the fourth called ball is a wild pitch or a passed ball and as a result (i) the batter-runner advances to a base beyond first base;

(ii) any runner forced to advance by the base on balls advances more than one base; or

111


Rule 10.12 to 10.13 (iii) any runner, not forced to advance, advances one or more bases, the official scorer shall score the base on balls and also the wild pitch or passed ball, as the case may be. (2) When the catcher recovers the ball after a wild pitch or passed ball on the third strike, and throws out the batter-runner at first base, or tags out the batter-runner, but another runner or runners advance, the official scorer shall score the strikeout, the putout and assists, if any, and credit the advance of the other runner or runners on the play as a fielder's choice.
Rule 10.12(f) Comment: See Rule 10.13 for additional scoring rules relating to wild pitches and passed balls.

10.13 WILD PITCHES AND PASSED BALLS A wild pitch is defined in Rule 2.00 (Wild Pitch). A passed ball is a statistic charged against a catcher whose action has caused a runner or runners to advance, as set forth in this Rule 10.13. (a) The official scorer shall charge a pitcher with a wild pitch when a legally delivered ball is so high, so wide or so low that the catcher does not stop and control the ball by ordinary effort, thereby permitting a runner or runners to advance. The official scorer shall charge a pitcher with a wild pitch when a legally delivered ball touches the ground or home plate before reaching the catcher and is not handled by the catcher, thereby permitting a runner or runners to advance. When the third strike is a wild pitch, permitting the batter to reach first base, the official scorer shall score a strikeout and a wild pitch. The official scorer shall charge a catcher with a passed ball when the catcher fails to hold or to control a legally pitched ball that should have been held or controlled with ordinary effort, thereby permitting a runner or runners to advance. When the third strike is a passed ball, permitting the batter to reach first base, the official scorer shall score a strikeout and a passed ball.

(b)

112


Rule 10.13 to 10.15
Rule 10.13 Comment: The official scorer shall not charge a wild pitch or passed ball if the defensive team makes an out before any runners advance. For example, if a pitch touches the ground and eludes the catcher with a runner on first base, but the catcher recovers the ball and throws to second base in time to retire the runner, the official scorer shall not charge the pitcher with a wild pitch. The official scorer shall credit the advancement of any other runner on the play as a fielder's choice. If a catcher drops a pitch, for example, with a runner on first base, but the catcher recovers the ball and throws to second base in time to retire the runner, the official scorer shall not charge the catcher with a passed ball. The official scorer shall credit the advancement of any other runner on the play as a fielder's choice. See Rules 10.07(a), 10.12(e) and 10.12(f) for additional scoring rules relating to wild pitches and passed balls.

10.14 BASES ON BALLS A base on balls is defined in Rule 2.00 (Base on Balls). (a) The official scorer shall score a base on balls whenever a batter is awarded first base because of four balls having been pitched outside the strike zone, but when the fourth such ball touches the batter it shall be scored as a "hit batter."

Rule 10.14(a) Comment: See Rule 10.16(h) for the procedure when more than one pitcher is involved in giving a base on balls. See also Rule 10.15(b), which addresses situations in which a substitute batter receives a base on balls.

(b)

The official scorer shall score an intentional base on balls when the pitcher makes no attempt to throw the last pitch to the batter into the strike zone, but purposely throws the ball wide to the catcher outside the catcher's box. If a batter awarded a base on balls is called out for refusing to advance to first base, the official scorer shall not credit the base on balls and shall charge a time at bat.

(c)

10.15 STRIKEOUTS A strikeout is a statistic credited to a pitcher and charged to a batter when the umpire calls three strikes on a batter, as set forth in this Rule 10.15. (a) The official scorer shall score a strikeout whenever a batter: (1) is put out by a third strike caught by the catcher;

113


Rule 10.15 to 10.16 (2) is put out by a third strike not caught when there is a runner on first before two are out; (3) becomes a runner because a third strike is not caught; or (4) bunts foul on third strike, unless such bunt on third strike results in a foul fly caught by any fielder, in which case the official scorer shall not score a strikeout and shall credit the fielder who catches such foul fly with a putout. (b) When a batter leaves the game with two strikes against him, and the substitute batter completes a strikeout, the official scorer shall charge the strikeout and the time at bat to the first batter. If the substitute batter completes the turn at bat in any other manner, including a base on balls, the official scorer shall score the action as having been that of the substitute batter.

10.16 EARNED RUNS AND RUNS ALLOWED An earned run is a run for which a pitcher is held accountable. In determining earned runs, the official scorer shall reconstruct the inning without the errors (which exclude catcher's interference) and passed balls, giving the benefit of the doubt always to the pitcher in determining which bases would have been reached by runners had there been errorless play. For the purpose of determining earned runs, an intentional base on balls, regardless of the circumstances, shall be construed in exactly the same manner as any other base on balls. (a) The official scorer shall charge an earned run against a pitcher every time a runner reaches home base by the aid of safe hits, sacrifice bunts, a sacrifice fly, stolen bases, putouts, fielder's choices, bases on balls, hit batters, balks or wild pitches (including a wild pitch on third strike that permits a batter to reach first base) before fielding chances have been offered to put out the offensive team. For the purpose of this rule, a defensive interference penalty shall be construed as a fielding chance. A wild pitch is solely the pitcher's fault and shall contribute to an earned run just as a base on balls or a balk.
Rule 10.16(a) Comment: The following are examples of earned runs charged to a pitcher: (1) Peter pitches and retires Abel and Baker, the first two batters of an inning. Charlie reaches first base on an error charged to a fielder. Daniel hits a home run. Edward hits a home run.

114


Rule 10.16
Peter retires Frank to end the inning. Three runs have scored, but no earned runs are charged to Peter, because Charlie should have been the third out of the inning, as reconstructed without the error. (2) Peter pitches and retires Abel. Baker hits a triple. While pitching to Charlie, Peter throws a wild pitch, allowing Baker to score. Peter retires Daniel and Edward. One run has scored, charged as an earned run to Peter, because the wild pitch contributes to an earned run. In an inning in which a batter-runner reaches first base on a catcher's interference, such batterrunner shall not count as an earned run should he subsequently score. The official scorer shall not assume, however, that such batter would have made an out absent the catcher's interference (unlike, for example, situations in which a batter-runner reaches first base safely because of a fielder's misplay of a ball for an error). Because such batter never had a chance to complete his time at bat, it is unknown how such batter would have fared absent the catcher's interference. Compare the following examples: (3) With two out, Abel reaches first on an error by the shortstop in misplaying a ground ball. Baker hits a home run. Charlie strikes out. Two runs have scored, but none is earned, because Abel's at-bat should have been the third out of the inning, as reconstructed without the error. (4) With two out, Abel reaches first on a catcher's interference. Baker hits a home run. Charlie strikes out. Two runs have scored, but one (Baker's) is earned, because the official scorer cannot assume that Abel would have made an out to end the inning, absent the catcher's interference.

(b)

No run shall be earned when scored by a runner who reaches first base (1) on a hit or otherwise after his time at bat is prolonged by a muffed foul fly; (2) because of interference or obstruction; or (3) because of any fielding error.

(c)

No run shall be earned when scored by a runner whose presence on the bases is prolonged by an error, if such runner would have been put out by errorless play. No run shall be earned when the scoring runner's advance has been aided by an error, a passed ball or defensive interference or obstruction, if in the official scorer's judgment the run would not have scored without the aid of such misplay. An error by a pitcher is treated exactly the same as an error by any other fielder in computing earned runs.

(d)

(e)

115


Rule 10.16 (f) Whenever a fielding error occurs, the pitcher shall be given the benefit of the doubt in determining to which bases any runners would have advanced had the fielding of the defensive team been errorless. When pitchers are changed during an inning, the official scorer shall not charge the relief pitcher with any run (earned or unearned) scored by a runner who was on base at the time such relief pitcher entered the game, nor for runs scored by any runner who reaches base on a fielder's choice that puts out a runner left on base by any preceding pitcher.

(g)

Rule 10.16(g) Comment: It is the intent of Rule 10.16(g) to charge each pitcher with the number of runners he put on base, rather than with the individual runners. When a pitcher puts runners on base and is relieved, such pitcher shall be charged with all runs subsequently scored up to and including the number of runners such pitcher left on base when such pitcher left the game, unless such runners are put out without action by the batter (i.e., caught stealing, picked off base or called out for interference when a batter-runner does not reach first base on the play). For example: (1) Peter is pitching. Abel reaches first base on a base on balls. Roger relieves Peter. Baker grounds out, advancing Abel to second base. Charlie flies out. Daniel singles, scoring Abel. Abel's run is charged to Peter (2) Peter is pitching. Abel reaches first base on a base on balls. Roger relieves Peter. Baker forces Abel at second bases. Charlie grounds out, advancing Baker to second base. Daniel singles, scoring Baker. Baker's run is charged to Peter. (3) Peter is pitching. Abel reaches first base on a base on balls. Roger relieves Peter. Baker singles, advancing Abel to third base. Charlie grounds to short, with Abel out at home plate and Baker advancing to second base. Daniel flies out. Edward singles, scoring Baker. Baker's run is charged to Peter. (4) Peter is pitching. Abel reaches first base on a base on balls. Roger relieves Peter. Baker reaches on a base on balls. Charlie flies out. Abel is picked off second base. Daniel doubles, scoring Baker from first base. Baker's run is charged to Roger. (5) Peter is pitching. Abel reaches first base on a base on balls. Roger relieves Peter. Baker reaches first base on a base on balls. Sierra relieves Roger. Charlie forces Abel at third base. Daniel forces Baker at third base. Edward hits a home run, scoring three runs. The official scorer shall charge one run to Peter, one run to Roger and one run to Sierra. (6) Peter is pitching. Abel reaches first base on a base on balls. Roger relieves Peter. Baker reaches first base on a base on balls. Charlie singles, filling the bases. Daniel forces Abel at home plate. Edward singles, scoring Baker and Charlie. The official scorer shall charge one run to Peter and one run to Roger. (7) Peter is pitching. Abel reaches first base on a base on balls. Roger relieves Peter. Baker singles, but Abel is out trying to reach third base and Baker advances to second base on the throw. Charlie singles, scoring Baker. Baker's run is charged to Roger.

(h)

A relief pitcher shall not be held accountable when the first batter to whom he pitches reaches first base on four called balls if such batter has a decided advantage in the ball and strike count when pitchers are changed.

116


Rule 10.16

(1) If, when pitchers are changed, the count is 2 balls, no strike, 2 balls, 1 strike, 3 balls, no strike, 3 balls, 1 strike, 3 balls, 2 strikes, and the batter gets a base on balls, the official scorer shall charge that batter and the base on balls to the preceding pitcher, not to the relief pitcher. (2) Any other action by such batter, such as reaching base on a hit, an error, a fielder's choice, a force-out, or being touched by a pitched ball, shall cause such a batter to be charged to the relief pitcher.
Rule 10.16(h) Comment: The provisions of Rule 10.16(h)(2) shall not be construed as affecting or conflicting with the provisions of Rule 10.16(g).

(3) If, when pitchers are changed, the count is 2 balls, 2 strikes, 1 ball, 2 strikes, 1 ball, 1 strike, 1 ball, no strike, no ball, 2 strikes, no ball, 1 strike, the official scorer shall charge that batter and the actions of that batter to the relief pitcher. (i) When pitchers are changed during an inning, the relief pitcher shall not have the benefit of previous chances for outs not accepted in determining earned runs.

117


Rule 10.16 to 10.17
Rule 10.16(i) Comment: It is the intent of Rule 10.16(i) to charge a relief pitcher with earned runs for which such relief pitcher is solely responsible. In some instances, runs charged as earned against the relief pitcher can be charged as unearned against the team. For example: (1) With two out and Peter pitching, Abel reaches first base on a base on balls. Baker reaches first base on an error. Roger relieves Peter. Charlie hits a home run, scoring three runs. The official scorer shall charge two unearned runs to Peter, one earned run to Roger and three unearned runs to the team (because the inning should have ended with the third out when Baker batted and an error was committed). (2) With two out, and Peter pitching, Abel and Baker each reach first base on a base on balls. Roger relieves Peter. Charlie reaches first base on an error. Daniel hits a home run, scoring four runs. The official scorer shall charge two unearned runs to Peter and two unearned runs to Roger (because the inning should have ended with the third out when Charlie batted and an error was committed). (3) With none out and Peter pitching, Abel reaches first base on a base on balls. Baker reaches first base on an error. Roger relieves Peter. Charlie hits a home run, scoring three runs. Daniel and Edward strike out. Frank reaches first base on an error. George hits a home run, scoring two runs. The official scorer shall charge two runs, one of them earned, to Peter, three runs, one of them earned, to Roger and five runs, two of them earned, to the team (because only Abel and Charlie would have scored in an inning reconstructed without the errors).

10.17 WINNING AND LOSING PITCHER (a) The official scorer shall credit as the winning pitcher that pitcher whose team assumes a lead while such pitcher is in the game, or during the inning on offense in which such pitcher is removed from the game, and does not relinquish such lead, unless (1) such pitcher is a starting pitcher and Rule 10.17(b) applies; or (2) Rule 10.17(c) applies.
Rule 10.17(a) Comment: Whenever the score is tied, the game becomes a new contest insofar as the winning pitcher is concerned. Once the opposing team assumes the lead, all pitchers who have pitched up to that point and have been replaced are excluded from being credited with the victory. If the pitcher against whose pitching the opposing team gained the lead continues to pitch until his team regains the lead, which it holds to the finish of the game, that pitcher shall be the winning pitcher.

(b)

If the pitcher whose team assumes a lead while such pitcher is in the game, or during the inning on offense in which such pitcher is removed from the game, and does not relinquish such lead, is a starting pitcher who has not completed (1) five innings of a game that lasts six or more innings on defense, or

118


Rule 10.17

(2) four innings of a game that lasts five innings on defense, then the official scorer shall credit as the winning pitcher the relief pitcher, if there is only one relief pitcher, or the relief pitcher who, in the official scorer's judgment was the most effective, if there is more than one relief pitcher.
Rule 10.17(b) Comment: It is the intent of Rule 10.17(b) that a relief pitcher pitch at least one complete inning or pitch when a crucial out is made, within the context of the game (including the score), in order to be credited as the winning pitcher. If the first relief pitcher pitches effectively, the official scorer should not presumptively credit that pitcher with the win, because the rule requires that the win be credited to the pitcher who was the most effective, and a subsequent relief pitcher may have been most effective. The official scorer, in determining which relief pitcher was the most effective, should consider the number of runs, earned runs and base runners given up by each relief pitcher and the context of the game at the time of each relief pitcher's appearance. If two or more relief pitchers were similarly effective, the official scorer should give the presumption to the earlier pitcher as the winning pitcher.

(c)

The official scorer shall not credit as the winning pitcher a relief pitcher who is ineffective in a brief appearance, when at least one succeeding relief pitcher pitches effectively in helping his team maintain its lead. In such a case, the official scorer shall credit as the winning pitcher the succeeding relief pitcher who was most effective, in the judgment of the official scorer.

Rule 10.17(c) Comment: The official scorer generally should, but is not required to, consider the appearance of a relief pitcher to be ineffective and brief if such relief pitcher pitches less than one inning and allows two or more earned runs to score (even if such runs are charged to a previous pitcher). Rule 10.17(b) Comment provides guidance on choosing the winning pitcher from among several succeeding relief pitchers.

(d)

A losing pitcher is a pitcher who is responsible for the run that gives the winning team a lead that the winning team does not relinquish.

Rule 10.17(d) Comment: Whenever the score is tied, the game becomes a new contest insofar as the losing pitcher is concerned.

(e)

A league may designate a non-championship game (for example, the Major League All-Star Game) for which Rules 10.17(a)(1) and 10.17(b) do not apply. In such games, the official scorer shall credit as the winning pitcher that pitcher whose team assumes a lead while such pitcher is in the game, or during the inning on offense in which such pitcher is removed from the game, and does not relinquish such lead,

119


Rule 10.17 to 10.19 unless such pitcher is knocked out after the winning team has attained a commanding lead and the official scorer concludes that a subsequent pitcher is entitled to credit as the winning pitcher. 10.18 SHUTOUTS A shutout is a statistic credited to a pitcher who allows no runs in a game. No pitcher shall be credited with pitching a shutout unless he pitches the complete game, or unless he enters the game with none out before the opposing team has scored in the first inning, puts out the side without a run scoring and pitches the rest of the game without allowing a run. When two or more pitchers combine to pitch a shutout, the league statistician shall make a notation to that effect in the league's official pitching records. 10.19 SAVES FOR RELIEF PITCHERS A save is a statistic credited to a relief pitcher, as set forth in this Rule 10.19. The official scorer shall credit a pitcher with a save when such pitcher meets all four of the following conditions: (a) (b) (c) (d) He is the finishing pitcher in a game won by his team; He is not the winning pitcher; He is credited with at least  of an inning pitched; and He satisfies one of the following conditions: (1) He enters the game with a lead of no more than three runs and pitches for at least one inning; (2) He enters the game, regardless of the count, with the potential tying run either on base, or at bat or on deck (that is, the potential tying run is either already on base or is one of the first two batters he faces); or

120


Rule 10.19 to 10.20 (3) He pitches for at least three innings. 10.20 STATISTICS The League President shall appoint an official statistician. The statistician shall maintain an accumulative record of all the batting, fielding, running and pitching records specified in Rule 10.02 for every player who appears in a league championship game or post-season game. The statistician shall prepare a tabulated report at the end of the season, including all individual and team records for every championship game, and shall submit this report to the League President. This report shall identify each player by his first name and surname and shall indicate as to each batter whether he bats righthanded, lefthanded or both ways, and as to each fielder and pitcher, whether he throws righthanded or lefthanded. When a player listed in the starting lineup is substituted for before he plays on defense, he shall not receive credit in the defensive statistics (fielding) unless he actually plays that position during the game. All such players, however, shall be credited with one game played (in batting statistics) so long as they are announced into the game or listed on the official lineup card.
Rule 10.20 Comment: The official scorer shall credit a player with having played on defense if such player is on the field for at least one pitch or play. If a game is called (for example, because of rain) after a substitute player enters the field but before a pitch is thrown or a play is made, the official scorer shall credit such player with a game played in the batting statistics but shall not credit such player in any defensive statistics. If a game is called (for example, because of rain) after a relief pitcher enters the field but before a pitch is thrown or a play is made, the official scorer shall credit such pitcher with a game played in the batting statistics but shall not credit such pitcher in any defensive statistics or with a game pitched.

Any games played to break a divisional tie shall be included in the statistics for that championship season.

121


Rule 10.21 to 10.22 10.21 DETERMINING PERCENTAGE RECORDS To compute: (a) Percentage of games won and lost, divide the number of games won by the sum of games won and games lost; Batting average, divide the total number of safe hits (not the total bases on hits) by the total times at bat, as defined in Rule 10.02(a); Slugging percentage, divide the total bases of all safe hits by the total times at bat, as defined in Rule 10.02(a); Fielding average, divide the sum of putouts and assists by the sum of putouts, assists and errors (which shall be called chances); Pitcher's earned-run average, multiply the total earned runs charged against such pitcher by 9, and divide the result by the total number of innings he pitched, including fractions of an inning; and

(b)

(c)

(d)

(e)

Rule 10.21(e) Comment: For example, 9 innings pitched and 3 earned runs is an earned-run average of 2.89 (3 earned runs times 9 divided by 9 equals 2.89).

(f)

On-base percentage, divide the sum of hits, bases on balls and times hit by pitch by the sum of at-bats, bases on balls, times hit by pitch and sacrifice flies.

Rule 10.21(f) Comment: For the purpose of computing on-base percentage, ignore instances of a batter being awarded first base on interference or obstruction.

10.22 MINIMUM STANDARDS FOR INDIVIDUAL CHAMPIONSHIPS To assure uniformity in establishing the batting, pitching and fielding championships of professional leagues, such champions shall meet the following minimum performance standards:

122


Rule 10.22 (a) The individual batting, slugging or on-base percentage champion shall be the player with the highest batting average, slugging percentage or on-base percentage, as the case may be, provided the player is credited with as many or more total appearances at the plate in league championship games as the number of games scheduled for each club in his club's league that season, multiplied by 3.1 in the case of a Major League player and by 2.7 in the case of a National Association player. Total appearances at the plate shall include official times at bat, plus bases on balls, times hit by pitcher, sacrifice hits, sacrifice flies and times awarded first base because of interference or obstruction. Notwithstanding the foregoing requirement of minimum appearances at the plate, any player with fewer than the required number of plate appearances whose average would be the highest, if he were charged with the required number of plate appearances shall be awarded the batting, slugging or onbase percentage championship, as the case may be.

Rule 10.22(a) Comment: For example, if a Major League schedules 162 games for each club, 502 plate appearances qualify (162 times 3.1 equals 502) a player for a batting, slugging or on-base percentage championship. If a National Association league schedules 140 games for each club, 378 plate appearances qualify (140 times 2.7 equals 378) a player for a batting, slugging or on-base percentage championship. Fractions of a plate appearance are to be rounded up or down to the closest whole number. For example, 162 times 3.1 equals 502.2, which is rounded down to a requirement of 502. If, for example, Abel has the highest batting average among those with 502 plate appearance in a Major League with a .362 batting average (181 hits in 500 at-bats), and Baker has 490 plate appearances, 440 at-bats and 165 hits for a .375 batting average, Baker shall be the batting champion, because adding 12 more at-bats to Baker's record would still give Baker a higher batting average than Abel: .365 (165 hits in 452 at-bats) to Abel's .362.

(b)

The individual pitching champion in a Major League shall be the pitcher with the lowest earned-run average, provided that the pitcher has pitched at least as many innings in league championship games as the number of games scheduled for each club in his club's league that season. The individual pitching champion in a National Association league shall be the pitcher with the lowest earned-run average provided that the pitcher has pitched at least as many innings in league championship season games as 80% of the number of games scheduled for each club in the pitcher's league.

Rule 10.22(b) Comment: For example, if a Major League schedules 162 games for each club, 162 innings qualify a pitcher for a pitching championship. A pitcher with 161 innings would not qualify. If a National Association league schedules 140 games for each club, 112 innings qualify a pitcher for a pitching championship. Fractions of an inning for the required number of innings are to be rounded to the closest third of an inning. For example, 80% of 144 games is 115.2, so 115 innings would be the

123


Rule 10.22 to 10.23
minimum required for a pitching championship in a National Association league with 144 games scheduled and 80% of 76 games is 60.8, so 60 innings would be the minimum required for a pitching championship in a National Association league with 76 games scheduled.

(c)

The individual fielding champions shall be the fielders with the highest fielding average at each position, provided: (1) A catcher must have participated as a catcher in at least one-half the number of games scheduled for each club in his league that season; (2) An infielder or outfielder must have participated at his position in at least two-thirds of the number of games scheduled for each club in his league that season; and (3) A pitcher must have pitched at least as many innings as the number of games scheduled for each club in his league that season, unless another pitcher has a fielding average as high or higher and has handled more total chances in fewer innings, in which case such other pitcher shall be the fielding champion.

10.23 GUIDELINES FOR CUMULATIVE PERFORMANCE RECORDS (a) CONSECUTIVE HITTING
STREAKS. A consecutive hitting streak shall not be terminated if a batter's
plate appearance results in a base on balls, hit batsman, defensive
interference or obstruction or a sacrifice bunt. A sacrifice fly shall
terminate the streak. CONSECUTIVE-GAME HITTING STREAKS. A consecutive-game
hitting streak shall not be terminated if all of a batter's plate appearances
(one or more) in a game result in a base on balls, hit batsman, defensive
interference or obstruction or a sacrifice bunt. The streak shall terminate if
the player has a sacrifice fly and no hit. A player's individual
consecutive-game hitting streak shall be determined by the consecutive games
in which such player appears and is not determined by his club's games.

(b)

124


Rule 10.23 (c) CONSECUTIVE-GAME PLAYING STREAK. A consecutive-game playing
streak shall be extended if a player plays one half-inning on defense or if
the player completes a time at bat by reaching base or being put out. A
pinch-running appearance only shall not extend the streak. If a player is
ejected from a game by an umpire before such player can comply with the
requirements of this Rule 10.23(c), such player's streak shall continue.
SUSPENDED GAMES. For the purpose of this Rule 10.23, all performances in the
completion of a suspended game shall be considered as occurring on the
original date of the game.
