 The Giants rescinded that eviction notice and allowed the Yankees to stay until the end of the 1922 season, when the Giants renovated the Polo Grounds and increased seating capacity from 38,000 to 50,000.Before that however, the 1921 World Series between the Giants and Yankees became the first Subway Series, as match-ups between the Dodgers and the Giants were not referred to as Subway Series.After losing to the Giants in that World Series and again the following year, the Yankees moved across the Harlem River to the original Yankee Stadium in the Bronx, where they captured their first ever World Series from the Giants in 1923.
