An illegal act made by the pitcher to deceive the runners on base. When a balk is called, the ball is dead, and all runners get to advance one base. Ways in which a balk can occur:

  • The pitcher steps off the rubber without breaking his hands
  • The pitcher throws from the set position without coming to a complete stop before throwing
  • The pitcher throws to a base before stepping in the direction of that base first
  • The pitcher throws a pitch while the catcher is not in the catcher's box.
  • The pitcher fakes a throw to first base while standing on the rubber.
  • The pitcher goes into his natural pitching motion and fails to throw the ball to the plate
  • The pitcher pitches the ball before the batter is reasonably settled in the batter's box
  • The pitcher goes into a pitching motion while not on the rubber
  • The pitcher drops the ball while on the rubber
  • The pitcher steps on the rubber without the ball
  • Any unnecessary delay of the game
