Question: Who was the 2010 Wimbledon Championships – Women's Doubles defending champion who played alongside Venus Williams and who some commentators, players and sports writers regard as the greatest female tennis player of all time?
Context: The Women's Singles event at the 2010 Wimbledon Championships saw defending champion and top seed Serena Williams successfully defend her title with a 6–3, 6–2 win over Vera Zvonareva in the final, whilst failing to lose a set throughout the entire tournament.  The victory meant that Serena and her sister Venus had won nine of the last eleven Wimbledon titles between them, with only 2004 and 2006 going to another player. 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.  Zvonareva has won twelve WTA Tour singles titles and reached the finals of the 2008 WTA Tour Championships, 2010 Wimbledon Championships, and 2010 US Open.  She also was a bronze medalist at the 2008 Beijing Olympics.  In doubles, she has won four Grand Slam titles.  Two of the titles came in women's doubles, the first one at the 2006 US Open, partnering Nathalie Dechy, and the other at the 2012 Australian Open, partnering Svetlana Kuznetsova.  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. Meredith McGrath (born April 28, 1971) is a former professional tennis player.  She was born in Midland, Michigan, USA and made her debut on the Women's Tennis Association tour in 1988.  In her eight-year professional career Meredith achieved career-high world rankings of #18 in singles and #4 in doubles.  She notched victories over such players as Martina Navratilova, Martina Hingis, Anna Kournikova, Jana Novotna, Arantxa Sanchez Vicario, and Gigi Fernandez.  The pinnacle of her career came in reaching the singles semi-finals and doubles finals at the 1996 Wimbledon Championships.  In the singles she defeated Mana Endo, Amanda Coetzer, Nancy Feber, Katarína Studeníková and Mary Joe Fernandez before losing to Arantxa Sánchez Vicario.  An injury the week prior to the 1996 Wimbledon Championships eventually ended her career.  Meredith won the 1995 U.S. Open Mixed Doubles Championship (she was runner-up in 1989) and was the runner-up in the 1994 Australian Open Doubles Championship.  Meredith won three WTA singles titles: Oklahoma City and Eastbourne in 1994 and Birmingham in 1996, 25 doubles titles.  She retired with a 140–83 record in singles and a 189–40 record in doubles.  Meredith was recognized by Tennis Magazine as the WTA Comeback Player of the Year as she overcame near career-ending injuries to having her most successful competitive season in 1996.  In 1994 she received the WTA Tour Comeback Player of the Year. This is a list of the main career statistics of Czech professional tennis player Petra Kvitová.  To date, Kvitová has won 20 singles titles including two Grand Slam singles titles at the Wimbledon Championships, one WTA Tour Championships singles title, two WTA Premier Mandatory singles titles and four WTA Premier 5 singles titles.  She was also the bronze medallist at the 2016 Rio Olympics, a semifinalist at the 2010 Wimbledon Championships, 2012 Australian Open and 2012 French Open and a quarterfinalist at the 2011 Australian Open, 2012 Wimbledon Championships, 2013 Wimbledon Championships, 2015 US Open and 2017 US Open.  Kvitová reached her career-high ranking of world no. 2 on 31 October 2011. Peng Shuai (; ; born 8 January 1986) is a Chinese professional female tennis player.  She reached a career high ranking of World No. 1 in doubles by the Women's Tennis Association on 17 February 2014, making her the first Chinese professional tennis player (male or female, and in singles or doubles) to reach World No. 1.  She won a gold medal at the 2010 Asian Games, defeating Akgul Amanmuradova in the final.  At the 2013 Wimbledon Championships, Peng won her first ladies' double championship with Hsieh Su-wei of Taiwan and again won at the 2014 French Open with Hsieh. The 1884 Wimbledon Championships took place on the outdoor grass courts at the All England Lawn Tennis Club in Wimbledon, London, United Kingdom.  The tournament ran from 5 July until 19 July.  It was the 8th staging of the Wimbledon Championships, and the first Grand Slam tennis event of 1884.  The men's doubles (previously hosted by the Oxford University Club) and women's singles (originally planned by the London Athletic Club) were added to the Wimbledon championships, but these were not started until after the men's singles competition had been completed.  The first prize for the women was valued at twenty guineas, and the second prize was valued at ten guineas There were thirteen female competitors.  James Dwight, Arthur Rives and Dick Sears from the United States entered the men's singles event and were the first non-British and overseas players to enter the Wimbledon Championships.  The South Western Railway ran special trains to the ground from Waterloo and the temporary Stand A at the Centre Court was converted into a permanent and covered stand. 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. Jamie Murray is a professional tennis player who is the current British number one doubles player.  He has reached eight grand slam finals in total: (4 Doubles, 4 Mixed), he has won the mixed doubles at the 2007 Wimbledon Championships, 2017 Wimbledon Championships and 2017 US Open, and the men's doubles at the 2016 Australian Open and 2016 US Open, and has finished as runner-up in the men's doubles tournament at the 2015 Wimbledon Championships and 2015 US Open and in mixed doubles at the 2008 US Open.  Murray has been ranked as high as World No. 1 in the ATP doubles rankings, and was the first Britain to be ranked as world number one since the introduction of computerised world rankings in the 1970s.  He is currently ranked at world No. 5. Venus Williams and Serena Williams were the defending champions, but lost in the quarterfinals to Elena Vesnina and Vera Zvonareva. Serena Jameka Williams (born September 26, 1981) is an American professional tennis player.  The Women's Tennis Association (WTA) has ranked her world No. 1 in singles on eight occasions, from 2002 to 2017.  She became the world No. 1 for the first time on July 8, 2002.  On the sixth occasion, she held the ranking for 186 consecutive weeks, tying the record set by Steffi Graf for the most consecutive weeks as world No. 1 by a female tennis player.  In total, she has been world No. 1 for 319 weeks, which ranks her third in the Open Era among female tennis players.  Some commentators, players and sports writers regard her as the greatest female tennis player of all time.
