What happens when B1 hits F2 with the bat during the follow-through of a swing?

When B1 hits F2 with the bat during the follow-through of a swing, the situation is governed by rules concerning interference in the game. In this context, B1 is liable for interference because the player made contact with the catcher (F2) while swinging the bat. This constitutes a disruption of the defensive player's ability to make a play.

As a result, B1 is called out for interference, which is a crucial ruling in maintaining the flow of the game and protecting the integrity of defensive plays. Ensuring that offensive players do not interfere with the defense is essential, and in this scenario, the swing made by B1 resulted in an infraction, appropriately leading to an out being called.

This event underscores the importance of players' actions during a swing and the repercussions when they unintentionally or carelessly affect the opposing team’s ability to compete fairly.
