Mark Buehrle's teammates have joked for the last few weeks about the White Sox ace possibly making his final start for the team. "It's one of those things that I'm not too concerned about," said Buehrle, who is scheduled to start Monday night at U.S. Cellular Field against the Orioles. It could be the final hurrah for Buehrle with the Sox, who enter the final homestand of the season's first half knowing they must do more than win series from opponents. "I think we can (make a run) ...," Buehrle said Sunday after Jon Garland allowed no earned runs in seven innings of a 3-1 victory over Kansas City to complete a 6-1 trip. "I mean, we can get on a roll and start winning every series from here on out. But the teams in front of us, the way they're playing, it might be too late." In addition to the Mets and Braves, the Dodgers, Red Sox and Brewers are expected to increase their interest in Buehrle.
