Curveball arm action

v-mani
Don't really know what you can do besides practice. Maybe you are turning your wrist too early. Try keeping your motion like a fastball as long as possible. Hope some of this helps.

Vmani..i use to have the same problem..i practiced on it quite a bit cause i wanted to have a nice breaking slider and a 12/6 curveball...if you are still experiencing problems keep working on the curveball but learn a slider that breaks sharply...instead of hanging the breaking ball in the zone...try it u might be more effective..good luck

I've had the same problem until my last game, it was all in my GRIP. try messin around with different grips

You need to be quick with your hand out front. Dont think about twisting your wrist. The curve ball is done with the hand. Be fast late, not FB type of body effort, just quick handspeed out over your lead leg. Be certain that you maintain your fastball arm slot while attepmting to throw a quicker breaking ball, you dont want to slide underneath the ball and push it. It will also help dramatically if you shorten your stide on your curveball a little bit. This really makes it easier to get out over your lead leg and really make your hand move quick. Try not to be quick until your hand gets on top of the curve, then go quick and down from that point. I know im not as descriptive as Stephen King, so let me know what was lost in translation if anything. peace
