The Yankees moved across the Harlem River to the Bronx into Yankee Stadium. On April 18, 1923, the Yankees opened their new home against the Red Sox. Over 74,200 people watched the Yankees defeat the Red Sox, 4–1, in the first game played at the stadium. Babe Ruth hit the new stadium's first home run, christening the stadium as "The House that Ruth Built." Ruth would finish the year with a .393 batting average and the Yankees won their first World Series that year. Of the 24 players on the Yankees, 11 previously played for the Red Sox.
