As Ozzie Guillen sees it, Bobby Jenks is the only reliever coming back for sure next year. The White Sox manager likes Boone Logan, Ehren Wassermann and Matt Thornton, but said the closer is the only guaranteed returnee. "Right now, I can't sit here and say, 'We are going to bring this guy, this guy and this guy back,' because the only thing I think is the only one with a shot is Bobby," Guillen said. The Sox thought they had the long-term pieces in place when they traded for Andrew Sisco and David Aardsma and signed Mike MacDougal and Matt Thornton to contract extensions in the offseason. But going into Sunday's game, the four were a combined 7-11 with a 6.20 ERA, and Sisco and Aardsma were at Triple-A Charlotte. In all, the bullpen went into Sunday's game with a 15-21 record and a 5.54 ERA, and opponents were batting a collective .283 against the unit.
