To bankroll his Broadway ventures, Boston owner Harry Frazee sold Ruth to the Yankees prior to the 1920 season for $100,000, twice the highest price previously paid for a player. (Frazee also got a $300,000 loan.) Ruth responded by shattering his home run record with 54, and went on to break his own record twice more with 59 in 1921 and 60 in 1927. The sale initiated the enduring rivalry between the two teams and shifted the balance of American League power from Boston to New York. Whereas the Red Sox had won six pennants and five World Series in the American League's first nineteen seasons, the Yankees, who had never won a pennant, would rule in the 1920s and 1930s and win fourteen flags before the Red Sox would clinch another.
