What is the ruling when a batter creates an opportunity for an out on a runner due to interference?

In this scenario, the ruling is that the batter is out automatically when interference occurs that creates an opportunity for an out on a runner. This is based on the principle that when a batter interferes with the defensive team's attempt to make a play, it disrupts the normal flow of the game. Interference is a significant violation because it affects the positioning and rights of the defensive players as well as the status of the runners on base.

When interference is called, it is a clear signal that the batter has engaged in actions that obstruct the defense, leading to the automatic out. This ruling is designed to maintain fairness in the game and uphold the integrity of plays that could have progressed without the interference.

The other choices do not capture the essence of the interference rule accurately. Counting the run as completed does not apply when interference has occurred, as the play does not allow for an automatic run. Similarly, allowing the runner to advance based on umpire discretion does not align with the typical enforcement of interference rules, which focus on the immediate outcome of the interfering act. Additionally, requiring runners to return to their original bases does not apply in this context, as the automatic out directly affects the play's outcome.
