April 2, 1984 - After the New York Mets endured their 6th 90-loss season in the last 7 years, General Manager Frank Cashen, handed the reigns to rookie Manager Davey Johnson. Johnson, who had led the Mets' AAA team to the AAA World Series Championship in 1983, showed up to his press conference in cowboy boots and openly talked about utilizing statistics to better shape lineups and rotations for best matchups. After saying "I like working for smart men, and Frank Cashen is a smart man for hiring me", Johnson then asked Cashen why it took so long for Cashen to hire him. In his playing days, as Johnson was wrapping up his mathematics degree at Trinity, he took a computer programming class and used his skills on a computer owned by Orioles owner Jerry Hofberger to develop an optimized lineup that he gave to his HOF manager, Earl Weaver, ahead of the 1969 season; Weaver took the data and threw it in the trashcan. Now that he was in control, Johnson hired a data processing manager to run statics for him for the 1984 season, and was a pioneer in what would later become known as sabermetrics. While his first game as skipper didn't go so well, losing 8-1 with opening day starter Mike Torrez only lasting 1.1 innings, his statistical analysis laid the ground work as the Mets went from 90 losses in 1983 to 90 wins in 1984 and eventually the 1986 World Series championship.
I still think Johnson deserves to be in the Hall of Fame as his .562 winning percentage is 10th all-time among managers with 1,000 career victories, 13th all-time among managers who managed 1,500 games, and is the 2nd best winning percentage of any modern day manager (post 1960 - also excludes active managers Dave Roberts and Aaron Boone). He managed for 5 different franchises and holds a winning record at each stop, and he was only the 2nd manager ever to take 4 of those franchises to the playoffs.
