Although the New York Yankees' offseason priority is adding a starting pitcher, there is one high-profile free-agent starter who has apparently been crossed off the team's shopping list. No, it's not C.J. Wilson. It is Roy Oswalt, whose history of lower back problems make it highly unlikely that the Yankees would take a chance on him, despite his 159-93 career record and 3.21 ERA compiled over 11 National League seasons.
