My dd and I have worked on Hillhouse peel drop. Not getting alot of drop as she lets go of ball too late, but her fastball naturally drops at times causing ground balls. I dont want to give up on pitch. Her high school pitching coach told me that she lost speed on her fastball due to trying to throw peel drop. I dont agree. Is it true that she will loose speed on her fastball? Just need some feedback to contiune to work on drop as I think she should. Or... should we give up on drop and throw rise? She is getting close to speed needed for rise.
