The Winter Meetings start today, where GM Mike Hazen will be busy trying to improve a roster that went 69-93. He's already made two big moves, the first trading 2B Jean Segura, OF Mitch Haniger, and LHP Zac Curtis to the Seattle Mariners for RHP Taijuan Walker and INF Ketel Marte. Our pals at Inside the 'Zona further break down the two players the Diamondbacks got back in the deal. The second big move was non-tendering C Welington Castillo and RHP Rubby De La Rosa and then signing C Jeff Mathis.
