Game 327 | August 15, 1985 | Ray Miller
Although he never pitched in a major league game, Miller was one of the most respected pitching coaches in baseball in the 1980s. His success at Baltimore put him at the top of many managerial lists,_and when the Billy Gardner-led Twins got off to disappointing 27-35 start-in-1985; Miller was offered his first managerial job. The Twins improved to 50-50 the rest of the season, but he was fired near the end of the 1986 season when the Twins had a record of 59-80.
