 Dulko also reached the mixed doubles final at the 2011 US Open, with Edward Schwank.

 After breaking into the world top 100 in 1997, and reaching a career-high singles ranking of World No. 2 in May 2002, Haas's career was interrupted by injuries: he has twice dropped out of the world rankings due to being unable to play for twelve months.
 His first period of injury saw him miss the whole of the 2003 season, and he did not return to the world's top 10 until 2007.
 He also missed over a year's tennis between February 2010 and June 2011, but has since returned to play on the tour.
 He returned to World No. 11 in 2013 after reaching the quarterfinals at the French Open for the first time in his career.

 She notched victories over such players as Martina Navratilova, Martina Hingis, Anna Kournikova, Jana Novotna, Arantxa Sanchez Vicario, and Gigi Fernandez.

 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.

 Marray and Nielsen won the title defeating fifth seeded Robert Lindstedt and Horia Tecău who competed in their third consecutive Wimbledon final.
 Marray became the first British player to win the men's doubles at Wimbledon since Pat Hughes and Raymond Tuckey in 1936.
 Nielsen is only the second Danish winner of a Grand Slam title, following his own grandfather, Kurt Nielsen, who won the mixed doubles at the 1957 U.S. National Championships.
The Wimbledon effect (Japanese: ウィンブルドン現象, rōmaji: "Uinburudon Genshō", literally "Wimbledon Phenomenon") is a chiefly British and Japanese analogy (which possibly originated in Japan) which compares the tennis fame of the Wimbledon Championships, held at the All England Lawn Tennis and Croquet Club in Wimbledon, London, with the economic success of the United Kingdom's financial services industries – especially those clustered in the City of London.
 The point of the analogy is that a national and international institution (the All England Club) can be highly successful despite the lack of strong native competition, as in modern tennis Britain has produced very few Wimbledon champions, with only Ann Haydon Jones, Virginia Wade (both women's singles), Jonathan Marray (men's doubles), Andy Murray (men's singles), John Lloyd, Jeremy Bates, Jo Durie, Jamie Murray and Heather Watson (mixed doubles) winning titles in the Open Era.
