If there is some sort of magical troll, similar to the one in Harry Potter, raging through the dugout, I would allow helmets and bats to be tossed at him in the dugout.
Thats actually the most likely situation I could think of. Everything else, wind it up on your right hand, hop twice on the right foot, transfer the weight, and bring the arm quickly through the zone with a slight flick of the wrist at the end
