Cubs fill out Minor League coaching staff

CHICAGO -- The Cubs promoted Bill Dancy to Triple-A Iowa manager, named Tom Beyers the hitting coordinator, Dennis Lewallyn pitching coordinator and added former big leaguers Brian Harper and Mariano Duncan to the Double-A Tennessee staff.

The team made the announcements as it released the Minor League assignments for 2010 on Thursday. Dancy takes over at Iowa for Ryne Sandberg, who left the Cubs organization after not getting the manager's job with the big league team. Sandberg will manage the Phillies' Triple-A Lehigh Valley team in 2011.

Dancy, who joined the Cubs in 2010 after spending 35 years in the Phillies' organization, led the Smokies to an 86-53 mark this season, the best record in franchise history. Tennessee beat West Tenn in the North Division championship series, but lost in four games in the Southern League championship to Jacksonville.

Beyers replaces Dave Keller, who has joined manager Mike Quade's staff as a special assistant. This season was Beyers' second as Tennessee's hitting coach and the Smokies led the Southern League with a .285 team batting average, 120 home runs and 749 runs scored. He has been in Chicago's farm system as a Minor League manager or hitting coach since 2000, following 21 seasons in the Dodgers' organization. He was the Dodgers' Minor League hitting coordinator from 1995-99.

Lewallyn takes over coordinator duties for Mark Riggins, who was promoted to Quade's staff as pitching coach. Lewallyn just completed his fifth season in the Cubs' organization after spending 11 years in the D-backs' system, including 2002-06 as the Minor League pitching coordinator. He helped Tennessee post consecutive Southern League championship appearances in 2009 and 2010, while the Smokies' 3.79 team ERA last season ranked third in the league.

Dancy will be joined at Iowa by pitching coach Mike Mason and hitting coach Von Joshua, who were both with the team in 2010.

The Smokies' staff is new and includes Harper as manager, Marty Mason as pitching coach and Duncan as hitting coach. Harper, who played from 1979-95 with the Angels, Pirates, Cardinals, Tigers, Athletics and Twins, is currently managing Licey in the Dominican Winter League. Harper was on the Twins' 1991 World Series championship team. Duncan played for the Dodgers, Reds, Phillies, Yankees and Blue Jays from 1985-97 and has won two World Series championships (1990 and 1996).

Manager Buddy Bailey and pitching coach Tom Pratt return to Class A Daytona, and they will be joined by hitting coach Barbaro Garbey, who held that position at Class A Peoria.

Casey Kopitzke returns as manager of the Chiefs and will have former big league pitcher Jeff Fassero as his pitching coach and Ricardo Medina as the hitting coach. Fassero and Medina were both at Class A Boise in 2010.

Former big league catcher Mark Johnson will manage Boise and be joined by pitching coach David Rosario and hitting coach Desi Wilson, who held that job with the rookie league team.

Juan Cabreja will stay in Mesa as manager and be joined by pitching coaches Rick Tronerud and former Cubs pitcher Frank Castillo. Jason Dubois, who batted .300 with 20 homers and 59 RBIs last season for Iowa, will join the team as hitting coach.

Manuel Callado and Yudith Ozorio will remain as managers for the two Dominican rookie league teams.

Dave Bialas returns as the Cubs' Minor League field coordinator for the 10th consecutive season and his 17th year in the organization, and Franklin Font enters his third season as infield coordinator. Carmelo Martinez begins his 14th season and his fourth as Latin American field coordinator, and Marty Pevey returns as catching coordinator.

Lee Tinsley joins the organization as the outfield/baserunning coordinator, replacing Bobby Dernier, who was named to the big league staff in August as first-base coach. Tinsley has 10 years of coaching experience following a 14-year playing career that included five Major League seasons with Seattle (1993, '97), Boston (1994-96) and Philadelphia (1996).

Doug Jarrow enters his fourth season as Chicago's strength and conditioning coordinator, and Justin Sharpe returns as Minor League athletic training coordinator for the seventh straight year. Chuck Baughman enters his sixth season as rehabilitation coordinator, his 11th year with the organization.
