I need some advice re: bench player with an attitude

There's a sophomore on the HS Varsity team who is also on my U16 LL team. I have been hearing from DD and another kid that this girl who was always kind of quiet gas turned into a complainer/Debbie downer. Whenever one if the other players asks her for help with the equipment she always blows them off. When another player is having trouble at bat or boots a ball in the field, she is quick to dump on her.

She (and probably her parents) resent the fact that she may have been better than one or two freshmen that made the varsity team last year and are playing in front of her. She complains that she only gets into play in the last inning if at all. When she gets to hit she's nervous and usuall strikes out and then blames it on the umpire. In the outfield she's usuall pretty good but hasn't looked good when she has been out there this season.

The team has pretty good chemistry otherwise. She's really irritating some of the players and while DD used to stand up for her, she dumps on DD now too and others who don't deserve it, so DD sees her as ungreatful and undeserving when there are better teammates playing on JV.

So my question is, in private, should I let the parents in on the poor teammate that their DD has become (or is becoming)? Should I talk to the kid about "servant leadership" and the importance of being a good teammate? Or should I just let it go and leave it for others to sort out?

If the coach finds out just how bad she is, I know she won't be on varsity again next year. I'm thinking if she realizes the magnitude of the problem she has created by trying to build herself up by cutting others down, it could save a lot if headaches down the road for everyone.

I would deal with any issues that are on my team. If I didn't have any issues with her on the team I coached her on, there would be no conversations with her.

IME, most coaches understand and know exactly what's happening on with their team and expect the girls themselves to handle it in their own way. If this doesn't succeed or the coach is truly clueless, then he needs to be made aware of the situation...but by the girls on the team. Not you.

"Not my circus, not my monkeys."

I don't know your relationship with the player or her family, but this doesn't sound like the kind of hearsay you should act on. I would suggest this is something better policed by her teammates, not by adults who have nothing to do with the team she's on.

When you are finished rehabilitating the girl and her family, come see me. I have a large boulder in my backyard that needs to be pushed to the top of a mountain.

Wow, lots of typos in the OP!
Thanks for the responses, I shall mind my own beeswax.
She has driven off the road and I see her heading for a cliff, but you are right.let the team handle it.

The 33% Rule.

ABSOLUTELY bottom 1/3!
I've heard sue explain that before and it could never be more clear!!

So what is she like on your team??

Why not talk to her and find out if there's something wrong, if there's issues at home or what? Everyone has issues and some handle them better than others. On my team I have girls with a loved one in the hospital, one girl who was being bullied by another, a girl who looked depressed and spacey after her bf broke up with her, and one girl who was upset she rarely got to hit (she's the worst hitter on the team). Let them tell you about it if they want to, and offer some encouragement and some positive feedback on their game. As coaches we're also mentors and a trusted adult.
