What more do you want from your catcher? I mean, he actually started heading to the mound after the first punch was thrown. He almost tried to fight his way through the crowd too. That's a team player!
I saw the interview with Posey afterward. He didn't even try to hide it. "Yeah, there were some big boys going at it out there."
I heard a great idea this morning. If you want to cut down on the fights, handle it like the NHL. Everyone stay out of it and let the 2 guys fighting duke it out until they go to the ground and then jump in and separate it. In hockey, they don't care because everyone's padded up like football. In baseball, not so much.
