What occurs when a foul ball is caught by F2 after a deflection from a spectator?

When a foul ball is caught by the catcher after deflecting off a spectator, the moment of interference with the play is crucial. The act of interference by a spectator effectively halts the action on the field, meaning the ball is considered dead at that moment. Any play or attempt to catch the ball afterward does not count, as the interference has disrupted the continuity of the game.

Since the ball is ruled dead at the moment of interference, no further actions, such as legal catches or impacts on runner advancement, can occur until the situation is resolved according to the rules governing such plays. Consequently, this response captures the correct principle that governs foul ball situations and spectator interference.
