PITTSBURGH -- The Cubs have dismissed six members of the Minor League coaching staff, including Dave Bialas, who has been with the organization for 18 years, most recently as Triple-A Iowa's manager.
Bialas was the Cubs' Minor League field coordinator for 10 seasons before returning to managing this past season for the first time since 2001.
Also gone are Class A Daytona pitching coach Marty Mason, Class A Peoria manager Casey Kopitzke and hitting coach Barbaro Garbey, and Mesa Rookie League pitching coach Frank Castillo and hitting coach Jason Dubois. Kopitzke is headed to Marquette University to enroll in its sports law program. Castillo and Dubois both played for the Cubs.
Garbey was in his third season with the Chiefs and seventh in the Cubs organization. Kopitzke was in his fourth season as a Minor League manager in the Cubs' system.
