The Mets have a logjam at first-base that includes Ike Davis, Lucas Duda, Josh Satin, and Wilmer Flores. They clearly need to make a trade or two this winter to clear up some space on the roster, and also get rid of some unwanted pieces. Davis and Duda seem to be the most logical players to be dealt, as they haven't lived up to expectations at all. Several reports have indicated that the Mets are getting more calls on Davis than Duda. It is unknown which teams are calling, but here are who I believe would be the best fits to swing a deal with.
Cleveland Indians: 2013 First-Baseman: Nick Swisher
The Indians have needed a first baseman for years now, as once-hyped up prospect Matt LaPorta has turned out to be a huge flop. They had Nick Swisher playing first last season, which is his natural position. Swisher isn't going anywhere, but he could be moved to the DH role so the Indians could bring in a first-baseman. The Indians could deal away some of their young pitching to get Davis.
Colorado Rockies: 2013 First-Baseman: Todd Helton
The Rockies have many big decisions to make this winter. They'll likely hold onto their main pieces such as Troy Tulowitzki and Carlos Gonzalez, but Michael Cuddyer's status is up in the air. There is talk that he may move from right field to first base next season, now that long-time first baseman Todd Helton has retired. The Mets may also inquire on Cuddyer, so there actually is a possibility that he ends up in Queens and Davis ends up in Colorado. I can see Colorado as a big time bidder for Ike, and it'll be interesting to see how their offseason plays out.
It is unknown whether the Brewers are willing to bring back long-time first baseman/right fielder Corey Hart, but assuming they don't they'll have a huge hole to fill. Juan Francisco is a decent player because of his raw power, but the Brewers would be better off if they gambled on Davis. I expect them to certainly be in the market for Davis if Hart does not return to Milwaukee.
Tampa Bay Rays: 2013 First-Baseman: James Loney
Loney is likely going to leave via free agency, and the Rays will be searching for another inexpensive option that they could roll the dice on. Davis would be perfect for Tampa Bay, as the New York media has seemed to get in his head. Going to a low-key team like the Rays could be exactly what he's looking for, and luckily for the Mets, Tampa Bay has a few prospects that they could dangle in front of the Mets and see if they bite. I truly expect Davis to be traded to the Rays sometime this winter.
Toronto Blue Jays: 2013 First-Baseman: Edwin Encarnacion
I'm going to stick to my word and predict that the Jays are going to trade one of their top hitters this off-season. Whether that is Edwin Encarnacion, Jose Bautista, or even a smaller name like Adam Lind remains to be seen, but if Encarnacion or Lind are dealt, Toronto could bring in someone like Davis, who would give them cheap power, and can be had for a decent price. The Blue Jays would likely just have to cough up a bullpen piece or a low-grade outfield prospect to get Davis.
