What is the ruling when a pitcher in a wind-up position stops and moves their glove to their chest before delivering the pitch?

In this situation, the correct ruling is that the action of a pitcher in a wind-up position stopping and moving their glove to their chest before delivering the pitch is legal. This is because a pitcher is permitted to make adjustments to their delivery as long as they have not committed to their pitch to the batter. By moving their glove to their chest, the pitcher is not violating any rules or stepping outside the legal parameters set forth in the regulations governing pitching mechanics.

A pitcher has the discretion to pause during their delivery without penalty, and this movement does not fall into actions that would constitute a balk or other illegal pitching behavior. A balk typically involves actions that deceive the base runners or violate the proper process of delivery, but simply adjusting the glove position does not meet these criteria. Thus, the pitcher's action is considered within the legal boundaries, making it an acceptable practice during the pitching process.
