The Red Sox have ongoing contact with free agent pitcher Roy Oswalt, sources tell Jon Paul Morosi of FOXSports.com (Twitter link).
Oswalt, not far removed from being a dependable top-of-the-rotation starter, has seen his stock fall this offseason due to injury concerns, with recent rumors suggesting he could end up with a one-year contract worth somewhere around $8MM.
In addition to the Red Sox, the Rangers and Cardinals are also thought to be interested in adding the right-hander, who could pay off in spades for a contender if he's back at full strength.
Boston has been aggressively purusing rotation depth recently, although Oswalt would be more than insurance if he were to sign. The Sox added Aaron Cook and Justin Germano on minor league deals, and they may be nearing an agreement with Vicente Padilla.
