White Sox manager Ozzie Guillen is denying a radio report Monday night that he had agreed to a two-year contract extension. "It's not fair to talk about it to [general manager] Kenny Williams and [Sox Chairman] Jerry Reinsdorf while we're winning," Guillen said after a 4-0 loss to the Angels. Williams is also declining to comment on the rumor. "I'm not going to comment on any of that stuff," Williams said from Arizona, where he was preparing for his son Tyler's 8th-grade graduation.
