Starting Pitching Trade Candidates

As usual, starting pitching questions abound for many teams.  The Dodgers, for example, have to be concerned about the majority of their rotation.  Here's a look at starting pitchers who may be available a few months from now.

• The Orioles are already nine games out.  Kevin Millwood has a brilliant K/BB ratio so far, and may prove an unnecessary luxury for the O's.  Jeremy Guthrie is more interesting, since he's under team control through 2012.  The question is how comfortable the Orioles would be downgrading their rotation in the short-term.
• We touched on the White Sox yesterday.  Freddy Garcia could potentially be available this summer, or earlier if the Sox remain in contention but prefer Dan Hudson as the fifth starter.
• The Rays could probably spare Andy Sonnanstine now.  He'll move further down their depth chart once Jeremy Hellickson is deemed ready.
• The Royals' Gil Meche would have to prove he's healthy before a deal could occur.  Brian Bannister, under team control through '12, is more attractive.  There's no real reason for the Royals to move him, though.
• The Indians' Jake Westbrook is still shaking off the rust of Tommy John surgery.  The Tribe probably wouldn't mind shedding some of his $11MM salary.
• The Mariners' Ian Snell could be expendable if Doug Fister and Jason Vargas continue to perform well.
• Like the Orioles, the Pirates probably prefer not to weaken their rotation further.  GM Neal Huntington does hold two attractive pieces in Zach Duke and Paul Maholm, though.
• The Reds have a pair of well-paid veteran starters in Bronson Arroyo and Aaron Harang.  Harang is basically owed $15MM if traded, so he'd need to go on a strong run to be marketable.
• The Padres are enjoying a first-place tie, but they do have three veteran starters in contract years: Jon Garland, Kevin Correia, and Chris Young.
• Teams looking for aces have to hope the Mariners, Rockies, Cubs, Athletics, Astros, or Diamondbacks fall out of contention.  That might make Cliff Lee, Jorge de la Rosa, Ted Lilly, Ben Sheets, Roy Oswalt, and Brandon Webb available as rentals.  Wandy Rodriguez, under team control through '11, could be a hot commodity if the Astros commit to a rebuild (which would admittedly be out of character).  On a related note, WFAN's Mike Francesa says the Mets "have been sniffing around" Oswalt, and the Astros are listening for the first time.  However, ESPN's Adam Rubin has a source who believes the Mets have no chance at Oswalt.
