Throwing the Bat

[Spence]

I'm not an umpire. I didn't see the game. I have no agenda.

I read that in a tournament game at the high school level a girl hit a single but was declared out and ejected for throwing the bat. Story goes that she was warned previously for throwing her bat.

I always wondered if that was a real rule or one of those myths.

So I ask...

Is there a rule that calls for both an out and an ejection?

If not is there anything an umpire can do with a player who throws a bat?

Thanks
