"Mark Buehrle was among four White Sox who filed for free agency Sunday.

The Sox have exclusive negotiating rights with the 32-year-old Buehrle until 11 p.m. Wednesday. With 11 consecutive seasons with at least 200 innings, 30 starts and 10 victories, Buehrle figures to be one of the most sought-after left-handers, along with the New York Yankees' CC Sabathia and the Texas Rangers' C.J. Wilson."
