TP,
Sounds like you've got it under control, but here is how I see it anyway. If you are the captain of the team, then the team, in a sense, "belongs" to you.
If you are the one who procured a spot for the team, then it is yours. All the members of your team were INVITED to participate, presumably by you. If you can invite them to play, you may also invite them to LEAVE, especially if she is being a bit*h all the time!
I am not the team captain, but my captain has had several members removed from the team, nicely if possible, but if not, he has done whatever it took to get them gone. He now has respect from other teams for not putting up with the crap, and also has a good team that enjoys bowling together.
Bottom line? KICK THE BIT*H IN HER BVTT! You'll not only be happier, but I am betting the league will be also!

Brunswick will soon own the world.
You must face it.
There is no escape.
