Lockman managed the Cubs from 1972-1974, after succeeding his former New York Giants manager, Leo Durocher.
As a player, the line-drive hitter and speedy base runner had a .279 career batting average.
He was an all-star in 1952, played on two World Series teams, and in 1958, was a member of the Giants when they moved from the Polo Grounds to San Francisco.
On Oct. 3, 1951, his double set the stage for Bobby Thomson's dramatic National League pennant-winning three-run homer against the Brooklyn Dodgers.
Lockman spent more than 50 years in baseball, as a player for 15 seasons in the major leagues and as a manager, coach, front-office executive and scout.
Earlier this week, the Cubs and Giants observed a moment of silence for Lockman before their exhibition game in Mesa.
