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.
