According to the Chicago Tribune:
Former Cubs third base coach Chris Speier is expected to join Dusty Baker in Cincinnati as bench coach, sources said Sunday.
Speier replaced Wendell Kim as third base coach under Baker in 2005, and generally was considered one of the better third base coaches the Cubs have had in years. But when Baker and his coaching staff were let go after the 2006 season, Speier sat out the ’07 season.
The Cubs eventually re-hired Larry Rothschild as pitching coach.
Along with pitching coach Dick Pole, who was Baker’s bench coach in Chicago, Baker will likely have three former Cubs coaches on his staff, since former Cubs bullpen coach Juan “Porky” Lopez is also expected to wind up in a similar position with the Reds.
