D-backs Announce 2015 Player Development Staff

PHOENIX - The Arizona Diamondbacks (@Dbacks) named the organization's 2015 Player Development staff, as announced by D-backs Director, Player Development Mike Bell.

The D-backs, in 2015, will be in their seventh season with the Triple-A Reno Aces, ninth season with the Double-A Mobile BayBears and Single-A Advanced Visalia Rawhide, first with Single-A Kane County Cougars, third with the Short-Season A Hillsboro Hops, 17th with the Rookie-Advanced Missoula Osprey, fifth with the Rookie Arizona League (AZL) D-backs and 20th with the Dominican Summer League (DSL) D-backs.

The D-backs return all 6 of their coordinators and 22 members of the affiliate coaching staffs from last season when they were a combined 473-365 and their .564 winning percentage was second-best behind Texas (.565). The affiliates set a franchise record with 4 full-season clubs in the postseason and tied a club mark with 5 playoff teams (also 2012). Hillsboro won the Northwest League championship while Reno and Visalia lost their respective finals in the deciding game.  

Two members of last year's staff were promoted to the Major League club.
