I have a 16 yr. old student that is a soph. She is learning to pitch and has thrown some innings. Her wind up (pre-motion) was all convoluted and all over the place. With her hands together, she would take the ball up high and over the back of her head. Then, come down, separate the hands and swing the ball way up behind her. Then, she would push the ball, at release - with the biggest shoulder shrug I have ever seen.
So, I eliminated all of the pre-motion and worked on what she really needed, learning to pull the ball instead of push it.
She came in this weekend and said that she had been "stiff, with some minor soreness." "Amy, the pitching coach at the HS, makes me have the really big pre-motion up over my head." So, I said "Who is she?" She is the coach's daughter. She told my student that she is going to strain something, w/o a pre motion.
We discussed the problem and they said that the head coach is all about preventing injuries, so they might have a chance with him, but not the daughter.
I had her bring the arms straight up and out from the chest, but not over her head. And then, add the back swing. But, I do explain to her what is correct and how to teach younger girls.
First I am NOT a pitching instructor in fact I couldn't tell what is being done correct/incorrect anytime. I do have to ask this Amy, to me it looks like 80% or more Major D1 pitchers do have a "big pre-motion" and bring the ball over their heads. So are they all incorrect in your opinion? Not trying to start anything I am interested because a well known PC in my area teaches the same thing, little to no pre-motion yet thats not what I see at the College level.
