MLB seasons

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 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 line up of AL and NL franchises until 1953. The Chicago Orphans were renamed as the Chicago Cubs.
