I’ve been trying to throw a screwball for about a month now, without of tailing action but my hand is so far I the left side of the ball, it’s impossible to control. I’m a righty.
The screwball arm action is thrown much like a good circle changeup … only the grip is different. Are you “pronating” your throwing arm?
Make sure you don’t let your arm sweep across in front of you. Throw through to the target.
I’m definitly pronating my throwing arm.
