would it hurt your arm to be throwing a slider like a football? just wondering
I don't see a problem with that. When throwing a football you're suppose to pronate and follow-through with the thumb down.
Actually if it has a spiral on it like a football if is a gyro.
gyro is crap tho, its just a slider that fails to break ! lol
ok because throwing like that give u soooo much break. batters were swinging like it was an fastball inside when my catcher had to dive outside to catch it.
