What can a pitcher do in the windup position while on the pitcher's plate?

In the windup position, the pitcher can bring their hands together to take the sign. This action signifies that the pitcher is preparing to deliver the pitch, focusing on the signaling from the catcher while maintaining the necessary legal stance on the pitcher's plate.

Bringing the hands together is a standard practice that indicates readiness to either pitch or perform another action, as long as it is within the confines of the rules regarding pitching motions. It allows for a moment of focus and clarity before executing the pitch.

The other options incorporate actions that either violate the rules of pitching or stray from the standard practices of the windup position. For example, exceeding the number of allowable pumps or rotations could lead to a violation, while delivering a pitch without a sign can create confusion and disrupt the flow of the game. Stepping off the pitcher's plate at any time is also restricted during the windup phase as it can be considered a balk under certain circumstances.
