8.02 Pitcher Rules

The pitcher shall not –

(a) (1) bring the pitching hand in contact with the mouth or lips while in the 10-foot circle (18-foot circle in Intermediate (50-70) Division/ Junior/ Senior/ Big League) surrounding the pitcher’s plate; EXCEPTION: Provided it is agreed to by both managers, the umpire, prior to the start of a game played in cold weather, may permit the pitcher to blow on his/ her hands while in the 10/ 18-foot circle.

PENALTY: For violation of this part of the rule the umpires shall immediately call a ball and warn the pitcher that repeated violation of any part of this rule can cause the pitcher to be removed from the game. However, if the pitch is made and a batter reaches first base on a hit, an error, a hit batter, or otherwise, and no other runner is put out before advancing at least one base, the play shall proceed without reference to the violation.

(2) apply a foreign substance of any kind to the ball;

(3) expectorate on the ball, either hand or the glove;

(4) rub the ball on the glove, person, or clothing;

(5) deface the ball in any manner; or

(6) deliver what is called the “shine” ball, “spit” ball, “mud” ball, or “emery” ball. The pitcher is allowed to rub off the ball between the bare hands;

PENALTY: For violation of any part of Rules 8.02( a)( 2) through (6) the umpire shall: Call the pitch a ball and warn the pitcher. If a play occurs on the violation, the manager of the offense may advise the plate umpire of acceptance of the play. (Such election must be made immediately at the end of play.)

NOTE: A pitcher may use a rosin bag for the purpose of applying rosin to the bare hand or hands. Neither the pitcher nor any other player shall dust the ball with the rosin bag; neither shall the pitcher nor any other player be permitted to apply rosin from the bag to their glove or dust any part of the uniform with the rosin bag.

(b) Intentionally delay the game by throwing the ball to players other than the catcher, when the batter is in position, except in an attempt to retire a runner, or commit an illegal pitch for the purpose of not pitching to the batter (i.e. intentional walk, etc.)

PENALTY: If, after warning by the umpire, such delaying action is repeated, the pitcher can be removed from the game.

(c) Intentionally pitch at the batter. If in the umpire’s judgment, such violation occurs, the umpire shall warn the pitcher and the manager of the defense that another such pitch will mean immediate expulsion of the pitcher. If such pitch is repeated during the game, the umpire shall eject the pitcher from the game.
