In 1921, the Yankees made their first ever appearance in a World Series. Before all the World Series wins and AL pennants that they’re known for now, they were the upstarts taking on the New York Giants.
Led by Babe Ruth, in what was one of the best seasons in a career full of incredible seasons, the Yankees won 98 games, and won the American League by 4.5 games. The Giants won the National League by a similar margin to set up an all-New York World Series. Both teams were playing at the Polo Grounds at the time, which made this one of just three times the World Series was played exclusively at one stadium.
