My 10 yr old is getting to where she will take her hand to her stomach after releasing the ball instead of following through with her pitch. Any ideas on how to correct this.
The first thing you need to make sure of is that her arm circle is correct. If she's letting her arm come up over the top of her head instead of keeping it in front of her the hand path will not be correct. Then you have to try and determine if she's slowing down at the end of the circle trying to aim the ball by cutting her arm circle off and short arming it.
If her arm circle is good you need to have her do this drill. Have stand about 30' from you. Have her in the fully open position. Feet slightly wider than the shoulders, knees slightly flexed with more weight towards the balls of the feet and balanced. Now have her do full circles with her arm making sure she follows completely trough and extends the finger tips towards the catcher. What I tell the girls is to imagine they are reaching out trying to tickle the chin of the catcher with their finger tips as their hand comes up. Then I make them keep their arm moving all in one motion and bring their finger tips up and touch them to the top of their forehead. They do not step or close when doing this drill. It's not about speed or accuracy. What it does is do is force them to exaggerate the finish of the pitch and to rely on trusting their wrist snap to throw the pitch. After she becomes comfortable with it you'll find the speed and accuracy will increase on their own.
Without seeing the pitcher it is impossible to tell if this is a problem or not...with my pitchers, what they do after releasing the ball is of little concern, as long as they dont bring the arm to an abrupt stop...
