My daughter is 9 and will hopefully start pitching in 10U this fall. She has done lessons the last 1.5 yrs. and has been taught hello elbow, did not know what it was called until doing research on IR. Due to scheduling issues we can't go to her instructor anymore. We recently started with a new instructor and he teaches IR. Needless to say the first lesson was very hard for my daughter. I am a little apprehensive of making the switch. Please correct me if I am wrong, but with IR it is more natural and puts less strain on shoulder of pitchers. This seems like a good enough reason to go on with the switch. The other thing I have found is that it sounds like it will allow for better speed as she gets older. What would be the pros or cons of switching?
