What is required for F1 to legally feint to first base?

To legally feint to first base, the pitcher must disengage the pitcher's plate first. This rule is in place to prevent unfair deception while on the mound. Once the pitcher has disengaged, they are allowed to make a feint toward first base, which means they can mimic a throw or a movement intended to deceive a baserunner without the intent to actually throw the ball.

This requirement ensures that baserunners are not caught off guard or misled by a stationary pitcher who has not legally disengaged from their pitching position. It upholds the integrity of the game by maintaining a clear distinction between legal and illegal moves by the pitcher.

Understanding the rules surrounding feints and disengagement is crucial for both players and umpires, as it affects the strategy of base running and pitching. The other possible options do not correctly capture the legal requirements for making a feint toward a base.
