Williams sisters: 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.

Vera Zvonareva: Vera Igorevna Zvonareva (Russian: Ве́ра И́горевна Звонарёва ; ] ; born 7 September 1984) is a Russian professional tennis player.  She was introduced to tennis at the age of six and turned professional in 2000.  Her career high is world No. 2 by the WTA.

Her other two came in mixed doubles, the first at the 2004 US Open, partnering Bob Bryan, and her second at the 2006 Wimbledon Championships, partnering Andy Ram.

Grand Slam (tennis): The Grand Slam tournaments, also called majors, are the four most important annual tennis events.  They offer the most ranking points, prize money, public and media attention, the greatest strength and size of field, and greater number of "best of" sets for men.  The Grand Slam itinerary consists of the Australian Open in mid January, the French Open in May and June, Wimbledon in July, and the US Open in August and September.  Each tournament is played over a period of two weeks.  The Australian and United States tournaments are played on hard courts, the French on clay, and Wimbledon on grass.  Wimbledon is the oldest, founded in 1877, followed by the US in 1881, the French in 1891, and the Australian in 1905.  However, of these four, only Wimbledon was a major before 1924–25, when all four became designated Grand Slam tournaments.  Skipping Grand Slam tournaments—especially the Australian Open because of the remoteness, the inconvenient dates (around Christmas and New Year's Day) and the low prize money—was not unusual before 1982, which was the start of the norm of counting Grand Slam titles.

Rosewall won 9 slams in doubles with a career double grand slam.  He is considered to be one of the greatest tennis players of all time.  He had a renowned backhand and enjoyed a long career at the highest levels from the early 1950s to the early 1970s.  Rosewall was one of the two best male players for about nine years and was the World No. 1 player for a number of years in the early 1960s.  He was ranked among the top 20 players, amateur or professional, every year from 1952 through 1977.  Rosewall is the only player to have simultaneously held Pro Grand Slam titles on three different surfaces (1962–1963).  At the 1971 Australian Open he became the first male player during the open era to win a Grand Slam tournament without dropping a set.
