Brad Mills (born January 19, 1957 in Exeter, California) is a coach and a former player in Major League Baseball. He is in his second year as the Boston Red Sox bench coach.
Before the 2004 season, Mills was named to the job reuniting with Red Sox manager Terry Francona, his former teammate and roommate at the University of Arizona. Mills and Francona also played together with the Montreal Expos (1981-83), and Mills served as Francona's first base coach with the Philadelphia Phillies (1997-2000). Mills, who served as an advance scout for the Chicago Cubs, also managed eleven season in the minors in the Cubs, Rockies and Dodgers organizations (1987-2002), and coached with the Expos in 2003.
Mills reached the major leagues in 1980 and went on to hit a .256 batting average with one home run and 12 RBI in 106 games played for the Expos (1980-83). He divided his time between Triple-A and the majors in each of those seasons, and sustained a right knee injury that ended his playing career at the age of 29. A left handed hitter and primarily a third baseman, he also saw time at first base and second.
