The 2013 season unofficially began Tuesday night for the White Sox, who embarked on the planning stages after their elimination from the American League Central race.

"It's already starting, now that you can focus on something else," manager Robin Ventura said before the Sox blew a 3-1 lead in the ninth and lost 4-3 in 12 innings on Jason Donald's two-out single off Nate Jones.

Jake Peavy, in perhaps his last start with the Sox, had a one-hitter entering the ninth before Michael Brantley singled and pinch hitter Travis Hafner followed with a two-run home run.

The Sox's first move could be the long-anticipated shift of general manager Ken Williams to president, with assistant GM Rick Hahn taking over Williams' duties. The change is expected to be seamless, but the Sox have other, more pressing matters to address soon.

First baseman Paul Konerko will undergo surgery to remove debris from his left wrist Thursday at Rush University Medical Center.

Konerko insisted the discomfort didn't affect his batting average, which has dropped from .399 on May 27 to .299 entering Wednesday night's season finale.

"There was a span there for games after that, it didn't feel well," said Konerko, who missed three games in early June to have the particle flushed from his joint and felt soreness for about a week after the procedure. "Nothing worth writing home about."
