That little bitch should be benched, kicked out of the league, and made to apologize to every member of the other team. I'm not into being sweet to opposing teams and all that BS but that is just being a shitty person. And it doesn't end with the bitch catcher. Her coach knows she's doing it, the other coach knows she's doing it, no doubt her parents know she's doing it, and that is a play at the plate. There is absolutely no reason for the umpire to not catch it happening.
I can just imagine what kind of useless fucks her parents and coach are. In fact, I am going to guess that they are one and the same.
Blocking the plate is one thing, which actually isn't even allowed unless you are making a play on the ball or already have the ball. That is the same as punching a runner on their way by and in fact, the elbow has far more blunt force than her fist would have.
If it were my kid being elbowed, I'd be on that field in a heart beat.
