I guess she will have to work twice as hard to try and break her ingrained mechanics.
Welcome to our world! At the rec level and at younger ages, only a handful of kids are working on pitching before the season. Once the season starts, there's a flood of parents and coaches that want their kids to learn how to pitch. The kids get a lesson or two then are put in the circle and told to "throw strikes," "play catch with Sally" and "just let them hit it." It's important that they understand it takes time to put everything together--not just the form basics, but even the rules, routine, basic tactics and responsibilities. Ideally it's nice to see a kid start in Jan/Feb and be serviceable by the second week of the season. So much to do and so little time...
