The 1903 Major League Baseball season was contested from April 16 through October 13, 1903. The Pittsburgh Pirates and the Boston Americans were the regular season champions of the National League and American League, respectively. The Americans then defeated the Pirates in the first modern World Series, five games to three.[1]
The original Baltimore Orioles relocated to New York City and became the New York Highlanders; it was the last relocation of a major league franchise until 1953. The Chicago Orphans were renamed as the Chicago Cubs.
The Cincinnati Reds and Cleveland Naps played an unofficial best of 11-game exhibition series after the regular season, with Cleveland winning the series six games to three.[2]
