What occurs if a batter's interference affects the catcher’s ability to throw out a runner?

In the scenario where a batter's interference impedes the catcher's ability to throw out a runner, the appropriate ruling is that the batter is called out and the runner returns to their original base. This penalty is imposed to maintain the integrity of the game and to ensure that teams are rewarded based on fair play. Interference by the batter disrupts the defensive team's opportunity to make a play, thus justifying the call of the out against the batter.

The rationale behind this rule is that the offensive team should not gain an unfair advantage through actions that obstruct the defensive team's normal play. The rules are designed to uphold fairness and sportsmanship within the game. As a result, the return of the runner to their base signifies that the defensive team's chance to record an out was compromised due to the interference, while appropriately penalizing the batter for their actions.
