Adam Dunn told Fox Sports that he will consider retiring this offseason despite the fact that the Chicago White Sox slugger is under contract for $15 million in 2014.

Dunn, 33, has 30 home runs this season despite a .228 batting average and has 436 homers over his 13-year career.

But the two-time All-Star acknowledged Tuesday that he is not concerned about reaching the 500-homer mark or collecting his guaranteed salary for next year.

"I'm not coming back just to come back for money or because I have one year left [on my contract]," Dunn told Fox Sports. "I'm not coming back to chase home run numbers or whatever. If I end up with 499 and I'm not having fun, see ya -- 499 it is."

Although he has been a consistent power hitter since the beginning of last season, Dunn has struggled to a .199 batting average over 403 games since signing a four-year, $56 million deal with the White Sox prior to the 2011 season.

Dunn told Fox Sports that he considers this season "a great letdown" by the White Sox, who entered play Wednesday with a 56-81 record -- the third-worst in the majors.

"Winning is everything, especially now," he said. "That's why it's so tough. The expectations that not only I had, but we had as a team, were really high. For this to happen, I don't like the word 'devastating,' but it's probably tougher to handle than most."

Dunn also said that one of his deciding factors would be Chicago's chances of success in 2014 after the White Sox traded ace right-hander Jake Peavy and two-time All-Star outfielder Alex Rios this season.

"If it's looking like it's going to be one of those 'Oh boy' kind of years, that's going to determine a lot," Dunn said.
