Mark Buehrle was among among four White Sox who filed for free agency on Sunday.
The Sox have exclusive negotiating rights with the 32-year-old Buehrle until Wednesday at 11 p.m. With a 3.83 career ERA with 161 wins and 11 consecutive seasons with at least 200 innings, 30 starts and 10 wins, Buehrle figues to be one of the most sought-after free-agent left-handers along with the Yankees' CC Sabathia and the Rangers' C.J. Wilson.
Outfielder Juan Pierre, infielder Omar Vizquel and catcher Ramon Castro also filed but are not expected to be re-signed by the Sox. Buehrle, a fan favorite and one of three remaining Sox from the 2005 World Series championship team, might not be in the Sox' payroll-trimming plans as well, although the Sox reportedy are willing to offer a two-year contract. Their offer may hinge on a number of factors, including whether they trade lefty John Danks and what other teams are willing to give Buehrle in the open market. Buehrle is coming off a four-year, $56 million contract.
