MLB Trade Rumors: Tampa Bay Rays

The Houston Astros face four major obstacles in trying to trade right-hander Roy Oswalt - ESPN:

"When the trade market starts in earnest, some executives believe that the Rays will market Andy Sonnanstine, who is a longtime starter currently working out of the bullpen. Tampa Bay's rotation has remained intact, with each of the five starters making all of their scheduled starts, meaning that the Rays are one of the few teams with starting pitching depth. The Mets would be a potential fit for a Sonnanstine deal, and there were brief talks during the winter about a trade between the two teams."

Honestly, what do the Mets have that the Rays need that the Mets don't need themselves?
