In Situation F, what happens when B2 swings at a pitch but misses?

In this scenario, when B2 swings at a pitch but misses, the key factor is the concept of interference. If B2's swing results in interference with the catcher's ability to make a play, B2 is deemed out. This is consistent with the rules governing interference in baseball, where the batter must conduct themselves without disrupting the natural play of the game. Therefore, if B2 interferes with the catcher's ability to catch the pitch or throw to a base, the umpire would call B2 out, upholding the integrity of the play and ensuring that players receive fair chances without undue obstruction.

The other choices do not align correctly with the rules. B2 being safe at first base or simply missing the pitch does not take into account the potential for interference. Additionally, while R1 advancing to second base could occur under certain circumstances, it is not directly relevant to the action of B2 swinging and missing if interference is involved. Finally, B2 cannot be deemed out regardless of interference as that would disregard the specific circumstance of the play and the implications of interference.
