On May 29, 1989 the greatest third baseman to ever play the game and to wear Phillies pin stripes, Michael Jack Schmidt, retired from the game of baseball.
Number 20 retired with 548 home runs and 1,595 runs batted in. Schmidt was a 12 time National League All Star, a ten time Gold Glove winner, six time Silver Slugger winner, and a three time MVP. Of course Schmidt was also a key player during the greatest span in Phillies franchise history, culminating in the team's first World Series championship in 1980.
Schmidt would later have his number retired by the organization, the last player to receive the honor. In 1995 Schmidt was inducted to the Hall of Fame, along side Richie Ashburn.
