Hanley Ramirez is in the middle of a terrible slump. So, we can't blame him for being in a foul mood right now. But, didn't he learn anything from Amare Stoudemire?!?

After grounding out in the sixth inning of a game against the Cardinals yesterday, the Marlins third baseman walked back into the dugout and punched an electric fan. In doing so, he cut his knuckle open and needed to be taken out of the game to get stitches. And, to make matters worse, his manager Ozzie Guillen ripped him a new one after the game.

"Very stupid, very immature," Guillen said. "You're going to hurt yourself because you can't hit? Good hitters don't do that. Good hitters battle back and try to get better. Your injury doesn't just hurt yourself, you hurt your ball club…That made me mad. Players get hurt for no reason—hitting stuff. That's very childish. We're not kids. We're grown people. When you struggle and you're a great player, you have to try and be better. To be honest with you, I didn't even ask him [about it], I was so disappointed. We built this ball club around him."

Ouch. An injured hand and some ether from your manager? That's gotta hurt. Get well soon, Hanley.
