Game 160 | May 16, 1968 | Jim "Catfish" Hunter
Eight days earlier, Hunter, a future Hall of Famer, threw a perfect-game no hitter against the Twins in Oakland. It was the first perfect game in the American League since 1922. Hunter won 224 games for Oakland and New York over his 15-year major league career: Upon his induction to the Hall of Fame, he said he enjoyed his time with Oakland and New York equally and chose to be depicted without either team's insignia.
