First I would probably talk to her, then if that didn't work I would talk to my coach(es). If that ends up not working then I would bring it up to the team.

But..you are always going to have ball hogs, and if she's awesome your coaches won't care and there will be pretty much nothing you can do about it, as much as it sucks.
