Buster Olney of ESPN.com reports that the Diamondbacks have been working to get James Shields in the rumored potential three- to four-team trade. The last version of the megadeal involved the D'Backs, Rangers, Indians and Mariners, with the D'Backs targeting Asdrubal Cabrera. It sounds as if in this version the teams, and obviously who would be getting what, would change. Olney says that if Arizona acquires Shields, it would allow them to deal one of their young pitchers, presumably for a shortstop.
