What is the outcome if a pitcher in a set position freezes after receiving a sign?

If a pitcher in a set position freezes after receiving a sign from the catcher, the scenario is considered a balk. The rules governing baseball specify that a pitcher must deliver the pitch without unnecessary delays. When a pitcher pauses excessively after coming to a set position, it can be interpreted as deceptive behavior that can disrupt the flow of the game and potentially confuse the baserunners.

A balk is called to penalize the pitcher for this behavior, allowing all base runners to advance one base. This rule is in place to maintain fairness in play, ensuring that pitchers cannot gain an unfair advantage by freezing and potentially disrupting the timing of base runners. This understanding underscores the importance of adhering to the rules regarding pitching mechanics and game pace.
