In the 1923 World Series, the New York Yankees beat the New York Giants in six games. This would be the first of the Yankees' 27 World Series championships (as of 2020). The series was not played in a 2–3–2 format: as with the previous two Series (where both clubs had shared the Polo Grounds) the home field alternated each game, though this time it involved switching ballparks, as the first Yankee Stadium had opened this season.
