The Mad Dash, or Slaughter's Mad Dash, refers to an event in the eighth inning of the seventh game of the 1946 World Series between the St. Louis Cardinals and the Boston Red Sox.
The 1946 Boston Red Sox ran away with the American League crown by twelve games over the Detroit Tigers with a 104–50 record, and were heavy favorites in the World Series against the St. Louis Cardinals. They led the series three games to two as it headed back to Sportsman's Park in St. Louis for Game 6. The Cardinals won that game on sensational defense and a brilliant pitching performance by Harry Brecheen to bring the series to a deciding seventh game.
Game 7 was played in Sportsman's Park on October 15, 1946. After Red Sox center fielder Dom DiMaggio drove in two runs in the top of the eighth, the score was tied 3–3. DiMaggio pulled a hamstring during the play and was forced to leave the game; he was replaced by a pinch runner, Leon Culberson, who also replaced DiMaggio in center field in the bottom of the inning.
Cardinal right fielder Enos Slaughter led off with a single off of pitcher Bob Klinger. After a failed bunt attempt by Whitey Kurowski and a flyout to left field by Del Rice, Slaughter found himself still on first base with two outs. Left fielder Harry Walker stepped to the plate and, after the count reached two balls and one strike, Cardinals manager Eddie Dyer called for a hit-and-run.
