If the offensive team's coach calls for a balk when the pitcher has legally stepped off, what should be the ruling?

When the pitcher has legally stepped off the rubber, they are allowed to make a play on the runner or reset their position without penalty. In this context, calling a balk under these circumstances is not appropriate. A balk is typically defined as an illegal motion by the pitcher that deceives the runner, and this situation doesn’t fit that definition because the action taken by the pitcher was legal.

Since no infraction has occurred when the pitcher steps off correctly, the play remains valid, and the umpire should disregard the coach's request for a balk. This highlights an important understanding of legal versus illegal actions on the pitcher's part and reinforces the rules surrounding stepping off the rubber. Thus, the correct ruling is that no balk is called, as the action performed was within the legal framework of the game.
