My 15 year old DD has been pitching for about 5 years now. She has been to many of the pitching instructors in our area. I guess a majority of her instruction is coming from me. She has been somewhat successful. Last year she worked alot on her breaking pitches. Her top speed that I have recorded is around 53 mph.
I have done some video analysis and believe it is her closing of the hips at the same time as her release that is keeping her from increasing in velocity. every once in a while she will strike her hip at release.
I have Bill Hillhouse's DVD and am using his drills hoping it will help.
Any one have any other suggestions/drills for her to work on?
