1920 World Series

In the 1920 World Series, the Cleveland Indians beat the Brooklyn Dodgers, then known interchangeably as the Robins in reference to their manager Wilbert Robinson, in seven games, five games to two. This series was a best-of-nine series, like the first World Series in 1903 and the World Series of 1919 and 1921. 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.

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 fifteen (as of 2009) 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. In fact, Game 4 was the only game in which the losing team scored a run before the winning team had scored all of its runs. The lead never changed hands in any game.

This would be the last World Series until 1980 to feature two franchises that had not previously won a championship.
