ST. PETERSBURG, Fla. — Chicago White Sox manager Ozzie Guillen would like to see Mark Buehrle stay in his rotation for a long time.

Guillen said before Wednesday night's game against Tampa Bay that he's hopeful the left-hander, who could become a free agent after the season, will sign a contract extension before the White Sox return from a road trip next Monday.

The Chicago Sun-Times reported that the team and Buehrle, who has been the subject of trade talks, have been working on a new deal.

"I think he's going to sign. That's my hope," Guillen said. "But there are so many things — so many hard things in the middle."

Buehrle started Wednesday night's game.
