What is necessary if a batter swings and inadvertently hits the catcher?

Calling time for player safety is essential in the situation where a batter swings and inadvertently hits the catcher. This action is necessary to ensure the well-being of all players involved. The catcher, who is in a vulnerable position behind the plate, could be at risk of injury from an errant swing. By stopping the play, the umpire can assess the situation and ensure that the catcher is not injured before proceeding with the game.

It's important to note that the other scenarios would not appropriately address the safety concerns involved in this situation. Awarding the catcher a base could lead to confusion, as they have not been hit in the act of play, and players should not benefit from accidental contact. Continuing play without interruption would dismiss the potential risk to the catcher, and calling the batter out would not be warranted when the contact was truly inadvertent. Therefore, prioritizing safety by calling time is the most appropriate and responsible action an umpire can take in this instance.
