CHICAGO -- Cubs manager Dale Sveum has completed his coaching staff for 2013, naming David Bell as the third-base coach and removing the interim tag from hitting coach James Rowson.

Rowson was the Cubs' Minor League hitting coordinator and had taken over the big league team's duties when Rudy Jaramillo was dismissed June 13.

Bell, 40, managed in the Reds' Minor League system the last four seasons, most recently guiding the Triple-A Louisville club in 2012. Prior to Louisville, Bell was the manager for Double-A Carolina from 2009-11. The '09 season was his first as a manager or coach at the professional level after a 12-year Major League career, which ended in 2006.

A former infielder, Bell batted .257 in 1,403 Major League games for six different teams -- the Indians (1995, '98), Cardinals (1995-98), Mariners (1998-2001), Giants (2002), Phillies (2003-06) and Brewers (2006). Sveum was Milwaukee's third-base coach in '06.

Bell is a member of one of Major League Baseball's three-generation families, as he is the son of Buddy Bell and the grandson of Gus Bell. When David hit for the cycle on June 28, 2004, with the Phillies, he joined Gus as the first grandfather-grandson tandem in Major League history to hit for the cycle.

Bell replaces Pat Listach, whose contract was not renewed after the 2012 season.

The rest of Sveum's staff will stay intact. Bell and Rowson will join pitching coach Chris Bosio, first-base coach Dave McKay, bench coach Jamie Quirk, bullpen coach Lester Strode, and staff assistants Mike Borzello and Franklin Font.

Cubs extend assistant GM Bush for three years

CHICAGO -- Cubs assistant general manager Randy Bush received a three-year contract extension, one of several front-office changes announced Tuesday.

Bush, 54, was assistant general manager to Jim Hendry, and served as interim GM when Hendry was dismissed in August 2011. Bush, who played on the Twins' two World Series championship teams, helped Theo Epstein in his transition as president of baseball operations one year ago.

The Cubs also announced Louie Eljaua has been promoted to special assistant to the general manager and director of international scouting. Paul Weaver, who was the director, will now be an international cross-checker and coordinator for the Pacific Rim. Alex Suarez was promoted to assistant director of player development.

The team also said Mark O'Neal, the Cubs' athletic trainer since 2004, will stay with the organization but in a different role.

The Cubs named Tim Cossins as the Minor League field coordinator, and were in the process of hiring new Minor League hitting and pitching coordinators.
