In Situation B, if B1's bat hits his leg after the ball bounces off the plate, what is the correct call?

In the given situation, when the ball bounces off the plate and subsequently hits B1's leg, the correct ruling is that the ball is considered a foul ball. This is because the ball has not been hit in a manner that puts it in play, and B1's leg is deemed part of his person. According to the rules, if the ball strikes a batter while they are in the batter's box, the ball is immediately ruled a foul.

In this case, the impact with B1's leg creates a scenario where the ball cannot be called fair since it never had the chance to become a playable ball due to the foul. Furthermore, it is not regarded as intentional interference since the action leading to the ball hitting B1 was not a deliberate attempt to make contact after the ball had already been in play. As such, B1 is not penalized for interference in this scenario because the ball simply did not leave the area of being a foul play.
