Did Chris Carpenter yell at Mike Napoli?

ARLINGTON, Texas -- Television cameras caught Chris Carpenter shouting something after Mike Napoli flied out to the deepest part of the ballpark to end the sixth inning.

Several Rangers players thought Carpenter was yelling at Napoli, though it's unclear if that's the case. The Rangers' catcher said he didn't hear anything but was told about it later.

"Somebody brought it to my attention," Napoli said. "It's kind of unfortunate. I don't really know him. I don't know why he'd be yelling at me like that. I'm not going to get involved in anything like that. I don't know. I didn't hear anything. I don't know what I've ever done to make him think that. I'm not going to get involved in that."

Carpenter continued to yell (just to no one in particular) as he headed back to the Cardinals dugout and was clearly frustrated that the Rangers had tied the score in that inning.

Mitch Moreland saw Carpenter yelling but figured it was more about firing himself up.

"He's a fiery guy and you're in the heat of the moment," Moreland said. "Sometimes that can happen. We don't react to that kind of stuff. You just go out and play."
