KANSAS CITY -- Managers in the Royals' Minor League system are moving up and, while they're at it, going home.
Brian Poldberg is being promoted to manager of the Triple-A Omaha Storm Chasers after six years of piloting Double-A Northwest Arkansas. He succeeds Mike Jirschele, who has joined the Royals' coaching staff in Kansas City.
Poldberg lives in Carter Lake, Iowa, which is surrounded on three sides by Omaha, so he'll be right at home. A Kansas City coach for four years, 2004-07, Poldberg led the Northwest Arkansas Naturals to the Texas League championship in '10. He'll be joined at Omaha by pitching coach Larry Carter and hitting coach Tommy Gregg.
Vance Wilson will take over as manager at Northwest Arkansas, located in Springdale, Ark., where he makes his home. He spent the past two seasons as manager of Class A Wilmington. Wilson's staff with the Naturals will include pitching coach Jim Brower and hitting coach Andre David, who began this year as the Royals' assistant hitting coach.
Chino Cadahia, who was the Royals' Major League bench coach the past two seasons, will resume his previous role as advisor to player development. Jack Maloof, Kansas City's head hitting coach at the beginning of last season, will be special assistant to player development-hitting.
The Royals won't field a rookie classification team at Surprise (Ariz.) in 2014, so the manager there for the past four years, Darryl Kennedy, will become the Wilmington manager. Kennedy also managed the Blue Rocks in 2008.
Brian Buchanan will return for his second year as Class A Lexington (Ky.) manager. Back as rookie classification managers will be Oscar Ramirez at Idaho Falls (Idaho) and Tommy Shields at Burlington (N.C.).
