What is the ruling if F1 feints a throw to second base but does not follow through?

In the scenario where F1 feints a throw to second base but does not follow through, this action is deemed a balk. The rule regarding feinting and balks specifically dictates that a pitcher must not deceive the runners with misleading motions that are not completed. By merely feinting without following through, F1 has created an unfair advantage by making the baserunners believe that a play would be made, causing them to either hesitate or adjust their leads. This can disrupt the flow of the game and the integrity of the competition, leading to the ruling of a balk in such instances.

Other possibilities such as considering it a legal action or assessing no penalty wouldn’t adequately hold the player accountable for an act that creates confusion for baserunners. Also, the idea of a warning for such behavior would not align with the competitive rules in place, as the nature of a balk is to penalize the deception intended toward the baserunners.
