What is the ruling when a coach asks if an ambidextrous player can pitch from both sides?

The ruling that requires an ambidextrous player to choose one arm to pitch aligns with the regulations governing pitching in official games. This rule is in place to maintain the integrity of the game and ensure that teams can prepare appropriately for a pitcher’s style. When a pitcher enters the game, they must indicate their throwing arm and stick to that choice for the duration of their pitching appearance.

Allowing a pitcher to switch arms during an at-bat would create significant challenges for the opposing team, as they would not be able to effectively strategize against the pitcher's style, leading to an unfair advantage. This is why once the pitcher has made their choice, they are restricted to using that arm throughout the game or until they leave the mound.

This ruling ensures consistency and fairness in competition, allowing teams to both prepare and execute their strategies without the unpredictability of a pitcher being able to change sides mid-game.
