You could get her with an intentional foul i guess, or you could call her for an OOB violation since the ball touched another player on the court and then her OOB. That might be the lesser of two evils. A intentional foul right here seem preety harsh, close game, possible freethrows. Not saying I wouldn't do it, just depends on how hard she pushed the girl. Sometimes they leave us with little choice. I'm sure I'll here it for this but it wouldn't be the same forum if I didn't.
