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. It was also the first World Series and first Big Four championship series to feature two brothers on opposing teams, with Doc Johnston playing for Cleveland and Jimmy Johnston playing for Brooklyn. 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. The triple play was unassisted and turned by Cleveland's Bill Wambsganss in Game 5. Wambsganss, playing second base, caught a line drive off the bat of Clarence Mitchell, stepped on second base to put out Pete Kilduff, and tagged Otto Miller coming from first base. It was the second of 15 (as of 2022) unassisted triple plays in major-league baseball history, and it remains the only one in postseason play. Mitchell made history again in the eighth inning by hitting into a double play, accounting for five outs in two straight at-bats. The fifth game also saw the first grand slam in World Series history (hit by Cleveland's Elmer Smith) and the first Series home run by a pitcher (Cleveland's Jim Bagby, Sr.). And in that same game, Brooklyn outhit Cleveland but lost 8–1. Cleveland had won the American League pennant in a close race with the Chicago White Sox and the New York Yankees. The Sox's participation in the Black Sox Scandal the previous year had caught up to them late in the season, and their star players were suspended with three games left in the season, when they were in a virtual tie with the Indians. The Yankees, with their recently acquired star Babe Ruth, were almost ready to start their eventual World Series dynasty. For Cleveland, it would prove to be one of their few successes in a long history of largely either poor or not-quite-good enough clubs. It is notable that all seven games of the 1920 World Series were won by the team who scored first.
