In Major League Baseball, specific penalties are enforced when players fail to adhere to the pitch clock regulations:

  • Pitcher Violation: If a pitcher fails to begin his motion to pitch before the timer expires, the batter is awarded an automatic ball.1
  • Batter Violation: If a batter is not in the box and ready for a pitch by the 8-second mark on the timer, an automatic strike is assessed against them.1

Additionally, pitchers are limited to two disengagements (such as stepping off the mound or throwing to a base) per batter. If a pitcher attempts a third pick-off throw and it is unsuccessful, the runner is automatically awarded the next base.1
