"I don't think we have. I hope we haven't," Dunn said. "You work so hard during the offseason, during the season, putting yourself in a great position and obviously we had some injuries, but we just didn't play well when it mattered. That's tough for me and I would assume it's tough for everybody in the locker room.
"I'm sure everybody's going to say, 'Start over with a clean slate,' but I don't want to forget about last year. I want to remember how it felt basically getting knocked out of first place, because I know I didn't like it very much and I don't want it to happen again. You work so hard to put yourself in the position we were in and just to let stupid things happen. We just didn't play well at the end."
The White Sox held a three-game lead over the Tigers in the American League Central following a victory over the Royals on Sept. 18, but their 2-10 record over the next 12 games ultimately erased their postseason hopes. Detroit won the division and the American League pennant.
Manager Robin Ventura appreciates Dunn's sentiment, but he also doesn't want the team focusing on 2012 shortcomings as the 2013 season fast approaches.
"Major League Baseball isn't going to let us go to September and try to start it. There's a long way to go to get back to that point," Ventura said. "It's nice that it sticks in your skull about it, but the focus should be on getting back to the first game of the year and realizing it's a long way to get there."
