What is the ruling when B2 attempts to hit the ball and it goes directly into F2's mitt, then rebounds to F1?

In the scenario where B2 attempts to hit the ball, and it goes directly into F2's mitt before rebounding to F1, the correct ruling is that this is a foul ball. A hit that goes directly into the catcher's mitt without being touched by any other player is classified as a foul ball because it has not traveled through the strike zone or played through fair territory.

When a ball goes directly into a catcher's mitt from a bat, it is considered a foul unless it is caught on the fly, which would make it an out. However, since the ball rebounded back to F1 after being initially caught by F2, it indicates the ball never traveled into fair territory in a way that allows it to be considered a fair ball.

Consequently, the determination of a foul ball is rooted in the rules governing how and where the ball must travel after being hit. This ensures clarity on plays and helps to maintain the game's flow and fairness.
