The Pirates have had trade talks with the Diamondbacks about shortstop Didi Gregorius, tweets Jon Paul Morosi of FOX Sports. Last Wednesday, Adam Rubin of ESPNNewYork.com reported the D'Backs were making Gregorius available in trade, after Chris Owings won the team's starting shortstop job. Rubin wrote that the Diamondbacks seek an MLB-ready starting pitcher to offset the loss of Patrick Corbin.

Rubin implied potential interest from the Mets, and now we have another possible suitor in the Pirates. The Pirates enter the season with Jordy Mercer atop their shortstop depth chart, with top prospect Alen Hanson likely ticketed to return to Double-A. Though he's not Major League ready, the Pirates have a pitching prospect who's fairly close in Nick Kingham. Easier to acquire would be Jeff Locke, who will begin the season back at Triple-A, with, as he tells Rob Biertempfel of the Pittsburgh Tribune-Review, "a bit of a chip on my shoulder."

Aside from the Mets and Pirates, Jon Heyman of CBS Sports lists the Reds, Tigers, and Yankees as teams the D'Backs "have thought of as possibilities" for Gregorius.
