The 1903 major league baseball season began on April 16, 1903. The regular season ended September 29, with the Pittsburgh Pirates and the Boston Americans as regular season champions of the National League and American League, respectively. The postseason began with Game 1 of the first modern World Series on October 1 and ended with Game 8 on October 13. The Americans defeated the Pirates, five games to three.[1]
The defunct Baltimore Orioles were replaced by a new franchise in New York City known as the New York Highlanders; it was the last change to the lineup of AL and NL franchises until 1953. The Chicago Orphans were renamed as the Chicago Cubs.
