As I have become my 15 year old dd's pitching coach I am searching for help to teach her the drop curve. She has a change up as off speed but we need another pitch. We tried peel without success, though her fast ball does drop when she gets good spin. Please enlighten me on grip, stride length, balance, etc. We did some work and she had good movement when throwing T's with a four seam grip. I've read turn over to front hip as follow through but need help with other mechanics. Thanks
