I wanted to get some advice on the enclosed videos of my DD pitching. She just turned 13 years old. It appears from the videos that she is dragging her back leg and I am not sure the best way to correct it. It also looks more straight than most higher level pitchers. We have also been working on getting a good knee drive with her stride leg. It looks like DD is reaching with her foot instead of driving out with the knee. Any advice on drills or tips would be appreciated. I am also open to other advice on things I may be missing to help her get better. I am enclosing a slow motion video along with a couple other videos. Thanks in advance for any help.
