Chris Perez will not apologize after being caught on camera in a profanity-laced exchange with a taunting A's fan.

"I don't regret it," the Indians closer said. "Looking back it's not the best thing to be on the Internet and stuff. I had no idea they were videotaping it. I wouldn't have done it. Looking back, that's what he was planning. So he got me.

"You have to live and learn. Luckily, I didn't say too bad of stuff. It was pretty bad, but it could have been worse."

The incident took place on Sunday. A viral video shows the back of Perez while he's yelling at the fan.

He said that particular fan has been riding him in Oakland for the past four years when he shags balls in the outfield before the game.

"I ignored it for 1½ groups. Then I just said 'What's your problem?' " Perez said. "If you got something to say, come down to my face and say it down in the bullpen. That's what happened.

"It's one of those things ... four years and I'd had enough. I'm not even playing the game. I'm shagging. I understand during the game it's all part of the game. It wasn't just a random guy that I just pointed out. It was the same guy for four years who has just been on me and on me. The video shows his ulterior motives. It's unfortunate. It's out there and I've just got live and learn from it."
