Thank you everyone for your input...I appreciate it. Starsnuffer...by loading, do you mean using the legs? Sorry...I am just the "mom" and trying to decipher the language. Also, by the leap, do you mean the stride? She actually has a pretty long stride (compared to others I have seen). I have even gone as far as trying to have her crow hop (just to get the feel of the weight being forward and the resistance off the drag foot) but she can't do it. She has a hard time.
Hey Cola,
Carly, one of the pitching instructors that posts here frequently, has an article on this that can explain it better then me trying to summarize. It can be found here: Is Your Pre-motion Hurting Your Pitch? Find out if you're fake-loading
By loading, yes, I mean using the legs, or rather preparing the body and center of gravity to use the legs during the motion before the pitch. By the leap, I mean the stride. Yes, your daughter has a "long" stride, but she is not propelling herself off the rubber with her pivot (rear or left) foot. She is stepping long. What she should be doing is exploding off the rubber as if she were doing a standing long jump. You can try having her put the ball down and doing a few standing long jumps to get a feel for it. Work on this before you worry about that back leg.
