  • The player that assumes the pitcher’s position must remain within the “mound” 8-ft.-diameter circle, behind the machine, and on one side or the other until the ball is hit.  If the pitcher violates any of these requirements, then (1) The play will stand, even if the pitcher is involved in the play, and (2) The umpire(s) will warn the violating pitcher’s manager that if that same pitcher violates one or both requirements again, he/she will have to be removed fromt eh pitcher’s position.  The player can assume another position but cannot re-enter as a pitcher in that game.  The player may not be ejected from the game for this infraction.
  • If a batted fair ball hits any part of the pitching machine without touching any defensive player first, the ball is immediately dead.  The batter will be awarded first base.  All other runners return to the base that they occupied before the ball was hit unless forced to advance as a result of the batter being awarded first base.  If a batted ball fair ball is first touched by a defensive player and then hits any part of the pitching machine, it is a live ball.
