Our league uses USASoftball rules. In two recent games the same play happened with 2 different calls. In both plays the ball was over thrown into the batting teams dugout, and bounced off of bats in the dugout entrance back onto the field of play. Both times a dead ball was called. The first time the runners were not allowed to advance and stayed on the base they were on. In the second instance the umpire awarded an additional base to the runners. Which is correct?
