I believe what you're going to see is that the 10U HE pitchers are going to be more accurate than your DD and, therefore, they're the ones that are going to pitch. Especially since I am betting the HC is all about winning or pretty close to it. My thoughts to you, based on personal experience, is to have your DD work on hitting, fielding and throwing during practices (and at home) and work on pitching during personal time. This way she can get some good playing time and hone those skills. Then you two can work on IR together, which I can tell you, is a great learning experience for both of you. Hopefully, in a year or three, you can find a PI. Or, even better, she's just a natural at it and she pitches next year.
