What is the ruling if the batter interferes with the catcher while a runner from second is attempting to steal third base?

In this scenario, when the batter interferes with the catcher while a runner from second base is attempting to steal third, the primary concern is the catcher's ability to make a play on the runner. Interference by the batter can hinder the catcher's attempt to throw out the stealing runner, making it a violation.

The ruling in this instance is that the runner is considered out because the interference prevented the catcher from making a fair attempt at his play. The rule aims to protect the catcher’s right to throw without obstruction, ensuring fairness in the game. Thus, the enforcement of the rule results in the runner being returned to second base, thereby upholding the integrity of the play and the rules of baseball.

This rationale emphasizes the consequences of batter interference and its impact on the defense's ability to execute a play on an advancing runner.
