Jake Peavy likely will make his last start for the Chicago White Sox on Tuesday as he approaches free agency after the season.

The Sox hold a $22 million option for 2013 or they must pay Peavy $4 million on the way out the door. The Sox will decline the option year, but that does not mean they won't negotiate a new deal for less money and more years.

"I really have not thought about it," he said. "I have just wanted to stay focused here. I don't know it depends on if these guys want me back. It depends on what they value me as. I really have not had any (talks) with them."

At 32, Peavy will look for his last long-term deal with market value likely fetching him $12 million to $15 million on a two- or three-year deal. The Sox may be looking to go younger in their rotation and use some of the Peavy cash for that purpose.

After two-plus injury-riddled seasons with the Sox, Peavy made 30 starts and pitched over 200 innings for the first time since 2007 when he won the NL Cy Young award with the San Diego Padres. He enters Tuesday's game with just 11 wins, but likely would have had 16 or 17 wins with decent run support.
