The US Open has existed for more than 120 years, but there have been many changes over that time that have shaped the tournament into the modern Grand Slam event as we know it today.
The event was first held in August 1881 as the U.S. National Singles Championship for men, competing in both singles and doubles. Only clubs that were members of the United States National Lawn Tennis Association were permitted to enter. The very first Men's champion was Richard D. Sears, who went on to dominate the event for the next six years. The championships were staged at the Newport Casino, Newport, Rhode Island.
Six years after the men's nationals were held, the first official U.S. Women's National Singles Championship was held at the Philadelphia Cricket Club in 1897, followed by women's doubles in 1889.
After seven years at Newport, the Championships began to move around the country, with nine different venues hosting the event at least once.
In 1900, U.S. National Men's Doubles Championship was held for the first time. Tournaments were held in the east and the west of the country in order to determine the best two teams (sectional winners). These would then compete in a play-off - the winner would play the defending champions in the challenge round. This challenge round was abolished in 1920, and the knockout system that we know today was employed.
In 1968 when all five events were merged into the US Open at the West Side Tennis Club in Forest Hills, Queens, New York. That year 96 men and 63 women entered the event with prize money amounting to $100,000.
By 1978, the tournament moved to its current home at the hard courts of the USTA National Tennis Center
in Flushing Meadow, New York.
It is the last of the four majors and so has the potential to be the crucial last tournament to win for anybody gunning for a Grand Slam.
Past US Open winners include a glittering array of tennis greats: Sampras, Hingis, Edberg, Jean King, McEnroe, Wade, Nastase, Laver, Ashe and many other stars too numerous to mention.
Last years US Open featured the debut of instant replay and player challenges in a Grand Slam event,
although unfortunately that came a bit late for John McEnroe, who surely would have appreciated it.
The 2006 U.S. Open was full of unforgettable moments. Tennis icon Andre Agassi, after a brilliant 20-year career, said goodbye to the game he loves. Roger Federer clinched his third straight Open title, proving once again that he is the best in the world.
Maria Sharapova captured his first U.S. Open crown, leaving no doubt that she is the most dominant women's singles player today.
With a history dating back to 1881, the US Open has been a showcase of champions over the years with stars
like Ivan Lendl, Boris Becker, John McEnroe, Jimmy Connors, Pete Sampras, Andre Agassi, Andy Roddick and most recently three-time defending champion Roger Federer.
In the women's bracket, Serena and Venus Williams have combined for four titles in recent years but a new crop of stars like Kim Clijsters, Amelie Mauresmo, Lindsay Davenport and 2006 champ Maria Sharapova have emerged to challenge the Williams sisters.
The 2013 US Open was a tennis tournament played on outdoor hard courts. It was the 133rd edition of the US Open, the fourth and final Grand Slam event of the year. It is currently taking place at the USTA Billie Jean King National Tennis Center, and runs from August 26 to September 9.
Andy Murray and Serena Williams were the defending champions in the singles events. Williams successfully defended her title, but Murray was defeated in the quarterfinals by Stanislas Wawrinka. Rafael Nadal won the men's singles.
The 2012 US Open was a tennis tournament played on the outdoor hard courts at the USTA Billie Jean King National Tennis Center in Flushing Meadows Park, of Queens, New York City, United States. It was played from August 27 to September 10.
As a result of adverse weather conditions on September 8, which included a full evacuation of the National Tennis Center because of an upcoming tornado, another day was added to the schedule for the fifth straight year, with the women's final postponed to the afternoon of Sunday, September 9 rather than the previous evening, the men's semi-final between Novak Djokovic and David Ferrer suspended on September 8 and completed on September 9, and the men's final postponed to the afternoon of Monday, September 10.
The 2011 US Open was a tennis tournament played on the outdoor hard court. It began on 29 August and was originally scheduled to end on 11 September, but the men's final was postponed to 12 September due to rain.
Rafael Nadal and Kim Clijsters were the defending champions. Due to a abdominal muscle injury, Clijsters wasn't able to defend her title.
In the women's singles, Australia's Samantha Stosur had to play one of the longest women's singles matches, played one of the longest tie-breakers in US Open history, received her first ever code violation in her tennis career, had to wait three days to play her quarterfinal match, and being relocated from Arthur Ashe Stadium to the Grandstand in her semifinal match to reach her first ever US Open final.
The 2010 US Open was a tennis tournament played on outdoor hard courts, held from August 30 to September 13, 2010 in the USTA Billie Jean King National Tennis Center at Flushing Meadows, Queens, New York City, United States.
The tournament was initially going to finish with Men's Singles final on September 12, but was postponed due to rain on the last day and just before the men's tournament final. In the previous two years the tournament was also postponed because of weather.
Juan Martín del Potro and Kim Clijsters were the defending champions. Del Potro, due to a wrist injury, opted not to defend his title. Clijsters successfully defended her title with a score of 6–2, 6–1 in the final against Vera Zvonareva.
The 2009 US Open was a tennis tournament played on outdoor hard courts, held from August 31 to September 14, 2009.
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.
