The 2009 US Open was a tennis tournament played on outdoor hard courts, held from August 31 to September 14, 2009 in the USTA Billie Jean King National Tennis Center at Flushing Meadows, New York City, United States. Originally, it was scheduled to end with the men's singles final match on Sunday, September 13, but due to rain the tournament was extended by one day. Like the Australian Open, the tournament featured night matches.

Former World No. 1 and 2005 US Open women's singles champion, Kim Clijsters, competed in the 2009 US Open [1] after being granted a wild card entry, returning to professional tennis after more than two years of retirement. She made it to the women's singles semi-finals, where she knocked out the defending champion Serena Williams in controversial circumstances. In the final, Clijsters defeated Caroline Wozniacki, the first Dane, man or woman, to reach a Grand Slam final in the Open Era, in straight sets: 7–5, 6–3. Clijsters thus became the first mother to win a Grand Slam since Evonne Goolagong Cawley in 1980. In the process, she also became the first unseeded player and wildcard to win the tournament.

In the men's singles final, five-time defending champion Roger Federer lost to Argentina's Juan Martín del Potro in a match lasting over four hours.

Arthur Ashe Kids' Day

The Arthur Ashe Kids' Day was held on August 29, 2009, prior to the start of the tournament. It featured an exhibition tennis match involving American player Andy Roddick and Great Britain's Andy Murray, who were joined by actor and comedian Will Ferrell. American Idol winner Jordin Sparks performed her hit single "Battlefield", along with rising stars Honor Society and Justin Bieber. There were also tennis matches and contests featuring Serena Williams, Ana Ivanovic Andy Roddick, Roger Federer, Maria Sharapova, Kim Clijsters, and James Blake. The popular tennis and music festival, which included interactive games, musical entertainment and tennis clinics, was hosted by television personalities Susie Castillo and Quddus. [2]

The first day of the tournaments saw many seeds get through pretty easily in straight sets: Roger Federer, James Blake, Lleyton Hewitt, Nikolay Davydenko and Radek Štěpánek. The day also produced a couple of upsets, when Mikhail Youzhny continued 26th seeded Paul-Henri Mathieu's horrible US Open record by beating him in four. While, tall American John Isner did the same to 28th seeded Victor Hănescu by ending the Romanian's 2009 bid in three with the second set going to a tie-break 16–14. The exciting day continued with a couple of five-set marathons, with Simon Greul defeating Giovanni Lapentti, Guillermo García-López out-lasting Peter Polansky, and Jan Hernych surviving against Rainer Schüttler. The days last match featured America's hope Andy Roddick prevailing over Björn Phau in straight sets in a match that started at 11:00 pm. [17]

Day 12 (September 11)

All the matches that should have been played this day were postponed due to the continued rain.

Schedule of play

Day 13 (September 12)

Rafael Nadal needed 34 minutes to finish off Fernando González in their rain-interrupted quarterfinal, advancing 7–6, 7–6, 6–0 at the Arthur Ashe Stadium. Nadal led 7-6 and 3–2 in a second-set tiebreak when play was called off late Thursday evening. Precipitation throughout a gloomy Friday rendered play impossible, throwing the schedule into chaos and prompting a resumption on Saturday at noon.

Kim Clijsters won an entry into the women's singles final after a dramatic ending to her semifinal against Serena Williams. After losing the first set 4–6, Williams smashed her racquet into the ground, giving her a code violation warning for racquet abuse from the chair umpire. In the second set, down 5–6 (15–30), Williams had a foot fault called on her second serve, giving Clijsters two match points at 15–40. Williams started yelling at the line umpire, who reported to the chair umpire. As a result, she was penalized for another code violation, for unsportsmanlike conduct, meaning a point penalty for Williams, which meant that Clijsters was awarded the match 6–4 7–5 without playing the match point. [42] Williams later admitted that she was "pretty sure" she did foot fault. [43] After securing her thirteenth straight win at the US Open, Clijsters went on to play Danish youngster Caroline Wozniacki in the final, who beat her unseeded opponent Yanina Wickmayer 6–3 6–3.

Day 14 (September 13)

In the first match, Juan Martín del Potro defeated third-ranked Rafael Nadal easily, winning 6–2, 6–2, 6-2 and became the first finalist of the men's singles tournament. Del Potro's convincing victory, which echoed Caroline Wozniacki's takedown of crowd favorite Melanie Oudin in the quarterfinals, set the twenty-year-old Argentine up for his first Grand Slam final.

In the second semifinal of the women's doubles championship Cara Black and Liezel Huber defeated Samantha Stosur and Rennae Stubbs in three sets and they became finalist of the championship to defend which they got in 2008.

Lukáš Dlouhý and Leander Paes won the men's doubles defeating Mahesh Bhupathi and Mark Knowles also in three sets.

Del Potro's opponent in the men's championship match was decided in a contest between world number one Roger Federer and fourth-ranked Novak Djokovic, who lost to Federer in the final of the 2007 U.S. Open. Federer dispatched his opponent in straight sets, winning 7-6(3), 7–5, 7–5, to round out the final two players remaining from an original draw of 128 men's professional tennis players.

In the women's final, unranked Kim Clijsters capped off an impressive return to professional tennis with a win over ninth seed Caroline Wozniacki of Denmark, winning 7–5, 6–3, for her second Grand Slam title.
