In 2011, the facility opened a new show court, Court 17, located in the southeast corner of the grounds, seating 2,500 to 3,000, making it small in comparison to the facility's other show courts. Next in size after those courts — Arthur Ashe Stadium, Louis Armstrong Stadium, and the Grandstand (the latter with a capacity of 8,125) — the court has large television screens and Hawk-Eye electronic line-calling capability which allows for player challenges. In constructing the new court, foundations from the 1939 and 1964 World's Fair were discovered, and the water table was found to be several feet higher than expected. Because the playing surface of Court 17 is below ground level, the new court has received the nickname of "The Pit".
