No pitch
A no pitch is an umpire's ruling in baseball or softball in which a pitch thrown by a pitcher is neither a ball nor a strike. This is typically the umpire's call whenever the pitcher released the ball after the umpire called timeout. However, there are other instances in which this can be called.
Major League Baseball rules
The call is not directly defined in the MLB rulebook. However, it is still mentioned in a comment under Rule 6.02:Occurrence
There are various reasons an umpire would rule a no pitch:- If any umpire calls time while a pitch is being delivered.
- With nobody on base, the pitcher releases the ball and the ball fails to pass over home plate or a foul line.
- While the pitch is being delivered, the ball is interfered with while in flight.
- If an umpire believes the batter is not ready or if the batter is not in the batter's box, a no pitch may also be called.
- A home plate umpire not in a ready position to call a ball or strike may call a no pitch.
