context_page_description: The United States Open Tennis Championships is a hard court tennis tournament. The tournament is the modern version of one of the oldest tennis championships in the world, the U.S. National Championship, for which men's singles and men's doubles were first played in 1881.
  Since 1987, the US Open has been chronologically the fourth and final Grand Slam tournament of the year. The other three, in chronological order, are the Australian Open, the French Open, and Wimbledon. The US Open starts on the last Monday of August and continues for two weeks, with the middle weekend coinciding with the U.S. Labor Day holiday.
  The tournament consists of five primary championships: men's and women's singles, men's and women's doubles, and mixed doubles. The tournament also includes events for senior, junior, and wheelchair players. Since 1978, the tournament has been played on acrylic hard courts at the USTA Billie Jean King National Tennis Center in Flushing Meadows–Corona Park, Queens, New York City. The US Open is owned and organized by the United States Tennis Association, a non-profit organization, and the chairperson of the US Open is Katrina Adams.
context_section_description: The grounds of the US Open have 22 outdoor courts (plus 12 practice courts just outside the East Gate) consisting of four "show courts" (Arthur Ashe Stadium, Louis Armstrong Stadium, the Grandstand, and Court 17), 13 field courts, and 5 practice courts.
  The main court is the 23,771-seat Arthur Ashe Stadium, which opened in 1997. A US$180 million retractable roof was added in 2016. The stadium is named after Arthur Ashe, the African-American who won the men's singles title at the inaugural US Open in 1968, the Australian Open in 1970, and Wimbledon in 1975 and who was inducted into the International Tennis Hall of Fame in 1985. The next largest court is the 14,061-seat Louis Armstrong Stadium, which cost US$200 million to build and opened in 2018. The 6,400-seat lower tier of this stadium is separately ticketed, reserved seating while the 7,661-seat upper tier is general admission and not separately ticketed. The third largest court is the 8,125-seat Grandstand in the southwest corner of the grounds, which opened in 2016. Court 17 in the southeast corner of the grounds is the fourth largest stadium. It opened with temporary seating in 2011 and received its permanent seating the following year. It has a seating capacity of 2,800, all of which is general admission and not separately ticketed. It is nicknamed "The Pit", partly because the playing surface is sunk 8 feet into the ground. The total seating capacity for practice courts P1-P5 is 672 and for competition Courts 4–16 is 12,656, itemized as follows:
  Courts 11 & 12: 1,704 each
  Court 7: 1,494
  Court 5: 1,148
  Courts 10 & 13: 1,104 each
  Court 4: 1,066
  Court 6: 1,032
  Court 9: 624
  Courts 14 & 15: 502 each
  Courts 8 & 16: 336 each
  All the courts used by the US Open are illuminated, allowing matches and television coverage to extend into primetime. In 2001, the women's singles final was intentionally scheduled for primetime for the first time. CBS Sports president Sean McManus cited significant public interest in star players Serena Williams and Venus Williams and the good ratings performance of the 1999 women's singles final, which was pushed into primetime by rain delays.
