Pitching against the Astros tonight, Carlos Lee popped out and slammed his bat against the ground in frustration. Lee said in the post game that he got a pitch to hit and he popped it up and was upset for not taking advantage of it. Lee wasn't looking at Carpenter as you can see from the camera angle, but Carpenter approaches the baseline and starts yelling at Lee anyway. The fight got heated and both benches cleared, with Carpenter still yelling as Lee left for the dugout.
I have to say, I don't think there is an opposing player I dislike more than Chris Carpenter. He is completely unprofessional. Whines about the balls not being rubbed down perfectly to his preference, and this isn't the first time I've seen him try to start a fight over nothing.
