What occurs if a pitcher doesn't come to a complete set before delivering the pitch?

When a pitcher fails to come to a complete set position before delivering the pitch, it is classified as a balk. A balk is a violation that occurs when the pitcher makes an illegal motion while on the pitching mound. According to the rules, the pitcher must come to a complete stop in their set position before throwing to home plate or attempting to pick off a base runner. This requirement is in place to ensure that batters and base runners can anticipate the pitcher's actions.

When a balk is called, all runners on base are automatically awarded one base, which can impact the game's strategy and flow. This rule is designed to prevent pitchers from gaining an unfair advantage through deceptive motions. Therefore, the correct understanding of the situation highlights the importance of following the proper pitching protocols to maintain fairness in the game.
