That is what we discovered on Wikipedia relating to the Polo within the Metropolis:

The Polo Grounds was the name of three stadiums in Upper Manhattan, New York City, used mainly for professional baseball and American football from 1880 to 1963. The original Polo Grounds, opened in 1879 and demolished in 1889, was built for the sport of polo. Bound on the south and north by 110th and 112th streets and on the east and west by Fifth and Sixth (Lenox/Malcolm X) Avenues, just north of Central Park, it was converted to a baseball stadium when leased by the New York Metropolitans in 1880.

The third Polo Grounds, built in 1890, and renovated after a fire in 1911, was in Coogan's Hollow and was noted for its distinctive bathtub shape, with very short distances to the left and right field walls and an unusually deep center field.

The original Polo Grounds was home to the New York Metropolitans from 1880 to 1885, and the New York Giants from 1883 to 1888. The Giants played in the second Polo Grounds for part of the 1889 season and all of the 1890 season, and at the third Polo Grounds from 1891 to 1957. The Polo Grounds was also the home of the New York Yankees from 1913 to 1922 and New York Mets in their first two seasons (1962, 1963). Each version of the ballpark held at least one World Series. The final version also hosted the 1934 and 1942 All-Star Games.

In American football, the third Polo Grounds was home to the New York Brickley Giants for one game in 1921 and the New York Giants from 1925 to 1955. The New York Titans/Jets of the American Football League played at the stadium from the league's inaugural season of 1960 until 1963.

Other sporting events held at the Polo Grounds included soccer, boxing, and Gaelic football. Its final sporting event was a pro football game between the Jets and Buffalo Bills. Shea Stadium opened in 1964 and replaced the Polo Grounds as the home of the Mets and Jets. The Polo Grounds was demolished and a public housing complex, Polo Grounds Towers, was built on the site.
