PHOENIX -- After posting the second-best Minor League winning percentage last season, the D-backs will have consistency in their system with six managers returning to the same roles they held last year.

The D-backs' affiliates posted a combined 455-382 (.544) mark, the second-highest winning percentage behind the Astros' farm teams, which were 502-405 (.553).

Four Arizona affiliates qualified for the postseason last year, with Class A Hillsboro and Rookie-level Missoula winning their league titles.

The six managers returning to the roles they held last season are Phil Nevin (Triple-A Reno), Robby Hammock (Double-A Mobile), J.R. House (Class A Visalia), Shelley Duncan (Hillsboro), Joe Mather (Missoula) and Juan Ballara (Dominican Summer League).

Former big league shortstop Mike Benjamin, who managed the D-backs' Arizona Rookie League team last year, will move to Class A Kane County.

The D-backs will bring back all six of their field coordinators, while adding the roles of assistant coordinator, short-season field coordinator and short-season pitching coordinator.

The D-backs have also expanded their coaching staffs at Mobile, Visalia, Kane County and the Arizona League, adding a pair of coaches at Mobile and one each at the others.

Among the new Minor League coaching hires are former big leaguers Eddie Oropesa and Franklin Stubbs.

Oropesa, who pitched for the D-backs in 2002-03, will fill one of the new coaching roles in Mobile, while Stubbs, who played for parts of 10 seasons in the Majors, will serve as hitting coach in Missoula.
