The Urban Archaeology Program, led by archaeologist Lorena Vázquez Vallin, carried out excavations on the site at Guatemala No. 16. In the course of this work, the remains of the north side of the Ball Court or Teotlachco (game of the gods) were discovered: a platform oriented east to west, whose construction may have been contemporary with stages V (1481-1486), VI (1486-1502), and VII (1502-1521) of the Templo Mayor. The penultimate stage, located 6.45 m south of the temple of Ehécatl, is the best preserved, with an approximate width of 9 m.

Two staircases can be seen overlapping on the platforms, each less than a meter high, with their respective sidewalks on the north side. At the base of one of them, 32 human cervical vertebrae were found, which were part of an offering. The southern end of the platform is formed by the superimposition of three stuccoed walls in the shape of a slope, the penultimate stage of construction of which measures 1.95 m in height. The upper part shows remains of sidewalks from rooms and a stucco floor with holes for wooden posts.

In another excavation project carried out between 2016 and 2017, the remains of a stairway were discovered, which was probably used by players to enter the court. This structure is associated with the platform that delimits the ball court on the north side.
