Alex, I agree with everyone that IF the parent is that parent who is going to make a stink all over the place then maybe it's time to go.
I'd also say that some of this sounds contradictory. You said she had a really good tryout, then said she had quite a few errors, is slow, and is serviceable at the plate, which I read as slightly below average. I'm trying to figure what was the good part at the tryout and why she was taken. You said you thought the coaches could develop her. But the post implies that her playing time is limited and that's what has dad cranky. What were the expectations of the kid and the dad? Did they know she was #11 or #12 going in and that she would see limited time? While some development without playing time can be had in practice, I would expect a decent amount of game time would be needed at 10U for development.
It sounds a little bit like both sides might be guilty, but it does seem the coaches either took her for her personality and not her skill level (not her fault) or because they thought they could develop her and have failed (unless she's not trying, again not her fault). Weird thing about this age group. In my experience, kids who are world beaters at 10 are often not the studs by HS and 6 months may or may not be enough time to tell what you have.
While the circumstances may have been different, we had a similar experience last year. Our HC had apparently soured on a girl because he thought he could get a couple better players and singled out the #3 pitcher. As a result, he continually pulled her, blamed her for others' mistakes and generally made life miserable for them and caused a blow up. He then dismissed her, and signed up another girl who he had his eye on from his rec team. I don't think that's by any means what you are describing, but it happens. That was 12U. At 10U, I feel like unless you are a national level A team, you take your 11 or 12 kids and do what you can with them.
