The Cubs felt the pitch from Milwaukee's Derrick Turnbow to Mark DeRosa, a called third strike, was low and outside of the strike zone. The Cubs, who had a runner on base in the 12th, lost the game to the Brewers, 5-4.
"It was a heat of the moment thing," Perry said Tuesday. "I have a lot of respect for the umpires, no doubt about it. But I didn't like the last call of the game. It got a little heated and we exchanged words, not with Paul but with Brian [Gorman], the crew chief. We said our words and it was over with, that's it."
The Cubs had a runner on first base in the 12th inning, and Perry said he felt as if they still had a chance.
"I just didn't like the call and voiced my opinion about it," Perry said.
"It's over with as far as I'm concerned," he said. "It's not the first time I've had a word with the umpires, and hopefully it'll be the last time."
The umpires have to walk through the Cubs' dugout to get to their locker room, and pass through the same short runway as the players do to get to the clubhouse.
"It's not an ideal situation," Perry said. "They have to come off the field and we have to leave, too, and that's the only place to go. We happened to be walking off at the same time."
It's the Cubs' second run-in with the umpires in the hallway. After last Friday's game against St. Louis, Cubs manager Lou Piniella exchanged words with umpire Larry Young. On Monday, Piniella also had a few words with the crew.
"I was very complimentary of the umpires," Piniella said. "I said basically they made the right calls.
"I respect the umpires. I know they have a tough job. The only thing I mentioned last night was I didn't think the last pitch was very good. Outside of that, I had no complaints about anything."
