Red Sox: George Kottaras

Cubs: Chad Gaudin, Rich Hill
Brewers: Tony Gwynn Jr.
Indians: Anthony Reyes, Andy Marte
Twins: Boof Bonser, Philip Humber
Rays: Jeff Niemann
Orioles: David Pauley, Felix Pie
Also, some guys discussed in the comments section...not confirmed:
Mariners: David Aardsma
Some others via MLBTR: Josh Anderson, Blaine Boyer, Mike Gonzalez, Anthony Lerew, Derek Lowe, Greg Norton, David Ross, Rafael Soriano, Phil Stockman, Ronny Cedeno, Phil Dumatrait, Sean Burnett, Craig Hansen, Tyler Yates and Wes Littleton.
Of all of those listed, I would specifically like Rich Hill, Reyes, Humber and Niemann. I wouldn't be opposed to adding any of these guys, but Pauley and Kottaras are both iffy IMO. I'd also like to mention that Pie was recently traded to the O's, so he will probably make the team, and Rich Hill is likely going to be an Oriole as well, so cross those two off of your lists. The chances that Michael Wuertz doesn't stick with the Cubs are very low as well.
Side note-does anyone want to compile a list like this one for the Nats?
