The 58-year-old Molitor reportedly will be handed a three-year contract, replacing Ron Gardenhire, who was fired five weeks ago after 13 seasons.
Molitor, a native of St. Paul, Minn., and former University of Minnesota star, ranks 10th all-time in the major leagues in hits (3,319) over a 21-year career. He's the only player in major league history to triple for his 3,000th hit.
Molitor finished his career with a .306/.369/.448 slash line in 2,683 games.
He joins Mike Matheny (St. Louis), Don Mattingly (Los Angeles Dodgers), Robin Ventura (Chicago White Sox), Walt Weiss (Colorado) and John Farrell (with Toronto before Boston) as recent hires with no previous managerial experience.
Molitor spent this past season as a coach on Gardenhire’s staff overseeing base running, bunting, infield instruction and positioning as well as in-game strategy. Previously, he served as the Twins’ minor league base running/infield coordinator for 10 seasons.
Molitor was also hitting coach for the Seattle Mariners in 2004 and bench coach for Minnesota from 2000-01.
In 2001, he was an initial candidate to replace the retired Tom Kelly before Minnesota hired Gardenhire.
Molitor was a first-ballot Hall of Famer in 2004.
