What happens if F1 fakes a throw to first while in the windup position?

When a pitcher is in the windup position, they are expected to deliver the ball or come to a complete stop before throwing. If the pitcher fakes a throw to first base while in this position, it is considered a violation of the rules governing pitching. This action is classified as a balk because it disrupts the fair play and equilibrium expected in the game.

A balk is defined as an illegal motion by the pitcher that results in the cessation of play and can lead to base runners advancing. By faking a throw to first while in the windup, the pitcher is not acting consistently with the intended purpose of the windup, which is to deliver a pitch or provide a clear signal of play. Therefore, the correct understanding of this situation leads to the conclusion that it is a balk.
