Polo was played in the 1870s on a site just north of Central Park bound by 5th & 6th Avenues and 110th & 112th Streets. The site became know as the Polo Grounds. By 1883, baseball had taken over the site. The New Yorks (later called the Giants) of the National League played in the southeast corner of the park and the Metropolitans of the American Association played in the southwest corner. In 1889, when the Giants were evicted from the original Polo Grounds, they moved uptown to a stadium on the southern parcel of Coogan's Hollow. Also known as Manhattan Field, from the beginning it was called the New Polo Grounds (Polo Grounds II).

The Players League built a stadium called Brotherhood Park on the northern parcel of Coogan's Hollow for the 1890 season. After one season the league collapsed, and in 1891 the Giants moved into Brotherhood Park and changed the name to the Polo Grounds (Polo Grounds III). The third incarnation of the Polo Grounds burned down on April 14, 1911 and a fourth version was built on the same site with temporary stands for 1911. The infield stands were rebuilt with concrete for 1912, and the outfield concrete double deck was finished in 1922. The bleachers in left-center and center were of wood remaining from before the fire.
