Looking for a rule that describes what constitutes tagging the base for the purposes of making a force play. Scenario - batter hits ball to first. First base knocks down the ball diving. Sprawling he grabs the ball in his bare hand and tags first with his glove hand. Ruling was initially an out, but the ump reversed the call when he realized the ball was not in the glove.
I cant find anything in the rule book but did find the following at
Force-out. This only works on a runner or batter-runner who is forced to run to a base. Again, he has to be at risk and not touching a rightful base. If he is forced to run to a certain base, a defensive player in possession of the baseball can simply make contact with that base with any part of his body, usually his foot. This is easier and faster than the other way of getting someone out, i.e. tagging him with the baseball—which also works in this situation.
Any help out there?
