The Williams sisters are two professional American tennis players: Venus Williams (b. 1980), a seven-time Grand Slam title winner (singles), and Serena Williams (b. 1981), twenty-three-time Grand Slam title winner (singles), both of whom were coached from an early age by their parents Richard Williams and Oracene Price.  There is a noted professional rivalry between them – between the 2001 US Open and the 2017 Australian Open tournaments, they met in nine Grand Slam singles finals.  They became the first two players, female or male, to play in 4 consecutive grand slam singles finals from the 2002 French Open to the 2003 Australian Open; Serena famously won all 4 to complete the first of two "Serena Slams".  Between 2000 and 2016, a 17-year span, they collectively won 12 Wimbledon singles titles (Venus won 5 and Serena won 7).  By winning the 2001 Australian Open women's doubles title, they became the 5th pair to complete the Career Doubles Grand Slam and the only pair to complete the Career Doubles Golden Slam.  At the time, Venus and Serena were only 20 and 19 years old, respectively.  Since then they have gone on to add another two Olympic gold medals in the 2008 Beijing Olympics and the 2012 London Olympics.  Nearly a decade later, the duo would go on to win 4 consecutive grand slam doubles titles from 2009 Wimbledon through 2010 Roland Garros, which would catapult them to co-No.  1 doubles players on 7 June 2010.  Two weeks later, on 21 June 2010, Serena would hold the No. 1 singles ranking and Venus would be right behind her at No. 2 in singles.  Their most recent grand slam doubles titles came at the 2012 Wimbledon & 2016 Wimbledon events.  They remain very close, often watching each other's matches in support, even after one of them has been knocked out of a tournament. The 1968 US Open (formerly known as U.S. National Championships) was a tennis tournament that took place on the outdoor grass courts at the West Side Tennis Club, Forest Hills in New York, United States.  The tournament ran from 29 August until 8 September.  It was the 88th staging of the tournament and the fourth Grand Slam event of 1968.  It was the first edition of the tournament in the Open Era of tennis and as such for the first time offered prize money, totaling $100,000.  Arthur Ashe and Virginia Wade won the singles titles.  Ashe was still registered as an amateur and therefore not entitled to the $14,000 first-prize money, which instead went to runner-up Tom Okker, while Wade earned $6,000.  Frank Parker, at the age of 52, lost to eventual champion Arthur Ashe in the second round, and still holds the record for the oldest man to compete in a Grand Slam singles tournament. The 2012 US Open Men's Singles final was the championship tennis match of the Men's Singles tournament at the 2012 US Open.  In the final, Andy Murray defeated defending champion Novak Djokovic 7–6, 7–5, 2–6, 3–6, 6–2 to win the match.  It was the equal-longest US Open men's final in history, lasting 4 hours and 54 minutes (equalling the 1988 US Open final played by Ivan Lendl and Mats Wilander), and the equal second-longest men's final in the Open era, only behind the 2012 Australian Open final.  By winning the 2012 US Open, Murray became the first British man since Fred Perry in 1936 to win a Grand Slam singles title, and the first British man in the Open Era to do so.  The match is a significant part of the rivalry between the two players.  This match also marked a milestone for Murray, as it was his 100th match win at a grand slam tournament. Li Na (; ; born 26 February 1982) is a retired Chinese professional tennis player, who achieved a career-high WTA-ranking of world No. 2 on 17 February 2014.  Over the course of her career, Li won seven WTA singles titles and two Grand Slam singles titles at the 2011 French Open and 2014 Australian Open.  Li's rise to prominence came after those victories, which made her the first and only Grand Slam singles champion from East Asia and Asia as a whole.  Prior to this, she had already become the first player representing an East Asian and Asian country to appear in a Grand Slam singles final, a milestone she achieved at the 2011 Australian Open.  Li was also the runner-up at the 2013 Australian Open and 2013 WTA Tour Championships, a three-time quarterfinalist at Wimbledon and a semifinalist at the 2008 Beijing Olympic Games and 2013 US Open.  Among her other most notable accolades, she was the first Chinese player to win a WTA tour title at the Guangzhou International Women's Open in 2004, the first to reach a Grand Slam singles quarterfinal at the 2006 Wimbledon Championships, and the first to break into the world's top 10.  Her feats have sparked a major population growth of tennis players in East Asia, earning her the reputation as the region's tennis pioneer and trailblazer. Francesca Schiavone (] ; born 23 June 1980 in Milan) is an Italian tennis player who turned professional in 1998.  She won the 2010 French Open singles title, becoming the first Italian woman to win a Grand Slam event in singles.  She was also runner-up at the 2011 French Open.  Her career high ranking is world No. 4, achieved on 31 January 2011.  To date, Schiavone is the last one handed-backhand player to win a Grand Slam title on the women's tour. Olga Vasilyevna Morozova (Russian: Ольга Васильевна Морозова ) (born 22 February 1949) is a retired female tennis player who competed for the Soviet Union.  She was the runner up in singles at the 1974 French Open and 1974 Wimbledon Championships. Francesca Schiavone was the defending champion, but lost in the final to Li Na, 6–4, 7–6, making Li the first Asian and Chinese Grand Slam singles champion. Sandra Reynolds Price ("née" Reynolds; born 4 March 1934) is a former tennis player from South Africa who won four Grand Slam women's doubles championships and one Grand Slam mixed doubles championship.  Her best Grand Slam singles result was reaching the 1960 Wimbledon final, losing to Maria Bueno 8–6, 6–0.  Reynolds is the only female player from South Africa to have reached the Wimbledon singles final, and she is one of three to have reached a singles final in a Grand Slam.  In 1961, she was seeded no. 1 for the Wimbledon Ladies Singles Championship, making her the only South African player (man or woman) ever to be seeded first in a Grand Slam singles event.  She was the runner-up at the 1959 , losing to Sally Moore in the final.  Price won the German Championships in 1960, 1961, and 1962.  She was the runner-up at the 1959 Italian Championships, having defeated Bueno in a semifinal, then losing to Christine Truman in the final. The 1973 Queen's Club Championships was a tennis tournament played on grass courts at the Queen's Club in London in the United Kingdom.  The men's tournament was part of the 1973 Commercial Union Assurance Grand Prix circuit while the women's event was part of the 1973 Women's Grand Prix tour.  It was the 74th edition of the tournament and was held from June 17 through June 23, 1973.  Ilie Năstase and Olga Morozova won the singles titles. The 2017 Australian Open Men's Singles final was the championship tennis match of the Men's Singles tournament at the 2017 Australian Open.  It was contested between Roger Federer and Rafael Nadal, ranked 17th and 9th in the world respectively.  It was their record ninth meeting in a Grand Slam final in their rivalry, and their 1st meeting in a Grand Slam final since the 2011 French Open.  In a rematch of the 2009 Australian Open final, which Nadal won in 5 sets, Roger Federer won the duel in 5 sets, beating Nadal for the first time in a Grand Slam since the 2007 Wimbledon final.  He also trailed Nadal 3–1 in the final set but won 5 games in a row to win the title.  This ended a 6-match losing streak against Nadal in Grand Slam events.  Having lost all of their previous three encounters, this was the first time Federer defeated Nadal at the Australian Open and also marked Federer's first Grand Slam victory over Nadal outside the grass courts of Wimbledon.  Federer extended his record of Grand Slam men's singles titles to 18, marking the third time he broke his own all-time record, after breaking the previous record of 14, held by Pete Sampras.
