The Chicago Cubs lifted the interim tag from hitting coach James Rowson and named David Bell as their third-base coach on Tuesday. The Cubs also announced that assistant general manager Randy Bush received a three-year contract extension. Rowson had replaced Rudy Jaramillo, who was fired in June, after serving as a minor-league hitting instructor. Bell, who replaces Pat Listach, managed triple-A Louisville in the Cincinnati Reds' minor-league system this past season. The former major-league infielder was manager of the Reds' double-A team from 2009 to 2011. Listach's contract wasn't renewed after the season.
