Rule 8.00: The Pitcher FAQs

No, the pitcher does not have to throw to a base after disengaging. Additionally, the pitcher does not need to disengage in order to throw to a base from either the wind-up or stretch/set position while on the pitcher’s plate.

There is no requirement to stop from either the windup or the stretch/set pitching positions. One of the three legal actions from either position is for the pitcher to throw to a base for a pickoff throw attempt. This answer primarily applies to the upper divisions of baseball (Intermediate, Junior, and Senior Divisions), but is also true for the Majors Division and below as there is never a requirement to come to a complete stop.

Yes, a violation of “hands to the mouth” is not only a “ball to the batter” but also does count as a pitch towards the pitch count.

Not necessarily. In the upper Divisions of Little League baseball (Intermediate, Junior, and Senior) when the pitcher begins his motion to pitch, if the free foot passes behind the pitcher’s plate, this action would commit him to complete the pitch or, alternatively and in one motion, step and complete a throw to second base in an attempt to pick off a runner there. Once the foot passes the back edge of the pitcher’s plate, he would be unable to step and throw directly to first or third without committing a balk.

No. The plate umpire should judge the pitcher’s intent at this point.  If the pitcher steps away or off the pitcher’s plate or makes any other motion not associated with the natural motion to pitch to the batter, then ignore the initial contact with the pitcher’s plate.  If, however, the pitcher then appears to take a sign from the catcher or the dugout, or goes into the stretch/set, then the pitcher has commenced the natural motion to make a pitch. If the pitcher in any way attempts to quick pitch or deceive the offense, then a balk should be called.

This is really a judgement by the umpire. Just a step towards the bench or dugout would not necessarily end the visit.
