My daughter (just turned 10) is currently pitching for a 10U travel team, but it's been suggested that she might be asked to pitch for our organization's 12U travel team that is thin on pitching. She throws about 45mph from 35ft and has very good control. As an experiment, we did back her up to 40ft with a 12in ball - and she was able to throw strikes at around 41mph. My fear is that she would get knocked around pretty badly by average 12U teams, and I also am concerned about the possibility of the 40ft distance and different ball - that it could mess up her pitching at 35ft with an 11in ball. How easily can pitchers transition between the different distances and ball sizes? Should I just say no or would the experience help her?
