DD has been with the same pitching coach (first coach) for two years, with a few breaks in between. DD is 13 and works very hard to improve, but she is not a gifted player. Pitching coach is former DI all American pitcher, and I think is a good instructor. The problem is my DD has not shown much improvement over the summer, but still puts in the effort and practice. The pitching coach doesn't seem that concerned, and takes for granted that we'll keep coming back. Is there a point where you make a change because the kid has heard too many times from same coach ?
