With the signing of Michael Cuddyer yesterday, the Mets have addressed their outfield need and now are zeroing in on an upgrade at shortstop. They are reportedly not "enthusiastic" about free agent shortstops Asdrubal Cabrera, Stephen Drew, and Jed Lowrie and instead will lean toward trading for an upgrade.
Per ESPN New York, a blockbuster trade with the Rockies for Troy Tulowitzki is "not happening," but Sandy Alderson is actively exploring his options elsewhere—with the Diamondbacks (Chris Owings/Didi Gregorius), the Mariners (Brad Miller), the White Sox (Alexei Ramirez), and the Cubs (Starlin Castro) as potential trade partners.
Having stockpiled young talent in the minors the past few years, the Mets have put themselves in a position where they could utilize the depth in their farm system to address needs at the major league level via trades. At this point, it's worth trading for a major league shortstop to make the 2015 team at least a couple of wins better.
