When does batter get a ball on balk?

A batter gets a ball on a balk when the pitcher makes an illegal motion while on the mound, typically involving deceptive actions that violate the rules of pitching. If the umpire rules a balk, the ball is typically called dead, and the batter is awarded a ball, which counts toward their total. This rule is designed to prevent pitchers from gaining an unfair advantage over the runners on base.
