Changes abound among Cubs' Minors staffs

Club has five new managers, including Bialas at Triple-A

The Cubs will have new managers at five of their eight Minor League affiliates, including Triple-A Iowa, where Dave Bialas takes the helm after 10 seasons as the organization's Minor League field coordinator.

The club announced its full slate of 2012 Minor League coaching staffs and coordinators on Wednesday, and there were changes at each of the top three affiliates. Besides Bialas, Buddy Bailey and Brian Harper switched spots, with Bailey taking over as manager at Double-A Tennessee and Harper moving to Class A Daytona.

Only one of the Cubs' new Minor League managers is also new to the organization. Bobby Mitchell took over managerial duties at Rookie level Mesa after spending the last nine years in the Angels organization, including five as a Minor League manager.

The full list of staffs is available in the Cubs' official news release.

Notable assignments include new Triple-A hitting coach Dave Heller, who was a Cubs special assistant in 2011 after spending the previous seven seasons as the club's roving Minor League hitting coordinator. At Tennessee, former big leaguer Jeff Fassero takes over as pitching coach after filling the same role at Class A Peoria last season and another longtime Major Leaguer, Mariano Duncan, is back for a second season as the Smokies' hitting coach.

The Cubs also named their Minor League coordinators for 2012:

• Taking over field coordinator duties from Bialas is Brandon Hyde, the Miami Marlins' bench coach for the past season and a half. He joins the Cubs as Minor League field coordinator after nine years with the Marlins.

• Dennis Lewallyn enters his second season as the Cubs' Minor League pitching coordinator, and his sixth in the Cubs organization.

• James Rowson, 35, is new to the organization and will be Minor League hitting coordinator after working the previous four seasons in the same role with the Yankees.

• Tom Beyers returns for his 13th season with the Cubs but his first as short season hitting coordinator, a newly created position. In this role, he will focus on players with Class A Boise, Rookie League Mesa and the Cubs' two Dominican clubs. Before joining the Cubs in 2000, Beyers spent 21 seasons in the Dodgers chain as a Minor League player, coach or manager. 

• Bill Dancy enters his first season as infield coordinator in his third year with the organization. He managed Iowa in 2011 after earning the 2010 Southern League Manager of the Year award while guiding Tennessee to the Southern League Championship Series. Dancy takes over for Franklin Font, who was named a special assistant on the Major League coaching staff. 

• Marty Pevey will be in his third season as catching coordinator, Lee Tinsley enters his second year as the organization's outfield/baserunning coordinator and Carmelo Martinez enters his 15th season in the Cubs organization and his fifth as Latin American field coordinator.

• In the athletic training room, Doug Jarrow (strength and conditioning coordinator), Justin Sharpe (Minor League athletic training coordinator) and Chuck Baughman (rehabilitation coordinator) will all retain their roles.
