Obviously I am not a pitcher, but I have no qualms about hitting a runner in the back if being provoked. I think it shows little class to play with the catcher, such as talking to them while up at bat and if you want to mess with me and tell me to bring it on, I will. I dont play my game soft and I don't throw soft, especially when I am irritated. I see nothing wrong with that and I don't understand why anyone would. Now if the girl was given a high-five because she hit her, and she hit her because she had a personal vendetta against her than I think that shows no class, and obviously the coach does not have control.
