Does anyone know if there is a rule in Pony Mustang league ball about barrel size & drop size. A kid was using a -11.5 coach pitch big barrel bat. IMO this is a 5-6 year old bat to help a little kid hit a T-ball or machine pitch & wasn't made for a Mustang big kid to swing so he can get a big barrel around quicker. I really didn't care if the kid used it so he could hit the ball I just thought it was more a safety issue of swinging a 15 oz 2 3/4 barrel bat. I didn't think there was anything in our rule book about it but the bat clearly says coach pitch only.
