This rumor has resurfaced in the latest boston globe.
Rich Harden is returning from his stint on the DL and a bunch of teams will be watching him closely. Since the Red Sox missed out on Roger Clemens I would expect them to make a strong push for a deal to gain Harden's services. They currently have a team to win the World Series and one strong move could put them over the top.
So what would you do?.....Without question Billy Beane would ask for one of the following: Jon Lester, Clay Buchholz, or Michael Bowden. Trying to evaluate these three pitchers and determine which one I would most likely give up is extremely difficult. It would cost a decent position player in Coco Crisp, Brandon Moss, David Murphy, Wily Mo Pena, etc. (not Jacoby Ellsbury).
I don't see Jon Lester, Buchholz, AND Bowden making the Red Sox roster in the future so I expect one of them to be traded. Is Rich Harden the guy you want to trade for? Personally I'm not sure...I would wait to see if the Florida Marlins make Miguel Cabrera available.
