According to Dan Martin of the New York Post, the Tigers have interest in acquiring Joba Chamberlain. Detroit has struggled to put together a consistent back end of the bullpen all season long, trying Joaquin Benoit, Jose Valverde, Bruce Rondon, among others. The Tigers could be desperate enough to see Joba as "a possible band-aid for their beleaguered bullpen," says Martin.
The Phillies, Braves and Giants have all been in the market for relievers, but none of them have interest in acquiring Joba. In fact, Danny Knobler of CBS Sports reports the exact opposite of Martin; that the Tigers have no interest in acquiring Chamberlain.
It would be really nice to trade him away, but he's unlikely to bring back anything worth while. Chamberlain might bring back the most value if he's packaged together with Phil Hughes, but the Tigers aren't looking for starting pitching. He has a 76 ERA+, so he wouldn't represent an upgrade over anyone other than someone who already shouldn't be on a big league team. Interested teams might just wait and see if the Yankees release him at this point, which is probably what they should do at this point.
