The Red Sox and Roy Oswalt continue to have "mutual interest" in one another, according to FOXSports.com's Ken Rosenthal. Oswalt previously stated he would prefer to sign with a team close to his Mississippi home, but all of his top choices now appear to be unrealistic landing spots due to budget constraints. Rosenthal notes that Boston ''hasn't ruled out the possibility of adding another starter'' and could look to solidify one of their remaining rotation spots behind Jon Lester, Josh Beckett and Clay Buchholz.
