Can the umpire call obstruction or interference on contact between players?

The correct answer highlights that obstruction or interference can only be called if the contact between players affects the continuation of play. In softball, these terms refer to specific situations where a defensive player hinders a base runner's path, or a runner makes illegal contact with a fielder.

If the contact does not influence the play—meaning it does not prevent a runner from reaching a base or a fielder from making a play—then it typically would not warrant a call. The umpire must assess whether the actions of either player interfered with the game’s flow or the other player’s ability to compete effectively. Therefore, it is essential for umpires to exercise their judgment to ensure that only meaningful disruptions result in penalties, maintaining the integrity of the game.

This understanding establishes how important it is for umpires to be vigilant during the game to discern between incidental contact and genuine obstruction or interference that affects play.
