Missed question a little bit, if glove comes off on hit like Eric said. Need control, they do not need thier glove but control of ball.
Example would be the OF throwing thier glove at a ball over thier head and the ball somehow ended up in it, no out keep running.
Baseball and softball are same.
The rule is asa 8-5-f. If a batted ball is contacted with detached equipment it is a 3 base award. If the ball could have cleared the fence if not for the contact it is a 4 base award.
That would be a dead ball, 3 base award for all runners. (ASA) Could be a 4 base award if umpire judges ball would have been over the fence on the fly.
Delayed dead ball.
