UPDATE 3:22PM EST: Rosenthal confirms the three teams closest to swinging the deal are the Nationals, Marlins, and Rangers.
2:27PM EST: Over his first eleven seasons, Mark Buehrle has averaged 200+ innings pitched, posting a stellar 120 ERA+ over that span (2001 to 2011). And he's still only 32 years old. As such, he's one of the better starting pitchers on the market. That's why it comes as no surprise that the lefty has generated considerable interest this offseason: 14 teams are reportedly pursuing him, and he currently has three three-year offers on the table.
