The New York owners return from their meetings in Chicago on October 20, 1920. The Yankees and Giants announce a deal to keep the Yankees in the Polo Grounds through the 1922 season:

It was announced last night that an agreement to this effect had been reached between Charles A. Stoneham, president of the Giants, and Colonel Jacob Ruppert, president of the Yankees. The Yankees have therefore abandoned their plans for a new stadium.

That would change. The Yankees opened the 1923 season across the river in the Bronx.
