In Game 1 of the 1968 World Series, Gibson struck out 17 Detroit Tigers to set a World Series record for strikeouts in one game, which still stands today (breaking Sandy Koufax's record of 15 in Game 1 of the 1963 World Series). He also joined Ed Walsh as the only pitchers to strike out at least one batter in each inning of a World Series game, Walsh having done so in Game Three of the 1906 World Series. After allowing a leadoff single to Mickey Stanley in the ninth inning, Gibson finished the game by striking out Tiger sluggers Al Kaline, Norm Cash, and Willie Horton in succession. Recalling the performance, Tigers outfielder Jim Northrup remarked: "We were fastball hitters, but he blew the ball right by us. And he had a nasty slider that was jumping all over the place."
