Cubs will look at Batista, now that Florida has said Lowell is staying.
White Sox will get Everett, not trade Colon.
Red Sox are looking for another SP, possibly Ponson (Penny will likely stay in FLA, see above).
Mets will for sure trade Benitez soon, now that they have acquired 2 top closer prospects, one in AAA. Likely teams interested are Yanks, Giants, and M's.
Rangers will trade away anything w/ a salary not named A-Rod, even though he is partly to blame for their current situation. (Why the hell do you give him input on team moves and let him convince you that Van Poppel and Chan Ho Park are good players? How convenient they are Boras clients as well).
