The 1920 World Series was the championship series for Major League Baseball's 1920 season. The series was a best-of-nine format played between the American League (AL) champion Cleveland Indians and the National League (NL) champion Brooklyn Robins, with the Indians defeating the Robins five games to two. The only World Series triple play, the first World Series grand slam and the first World Series home run by a pitcher all occurred in Game 5 of this Series. The Indians won the series in memory of their former shortstop Ray Chapman, who had been killed earlier in the season when struck in the head by a pitched ball.
