Most tennis Grand Slams (male)

Across all formats of the game, Rod Laver (Australia) is the only man to complete a calendar-year “grand slam” – winning the Australian Open, French Open, Wimbledon and the US Open – on more than one occasion. He accomplished it first in singles in 1962, and repeated the trick in the open era in 1969, when he won the last four of his 11 Grand Slam singles trophies. In the maximum 103 years to date in which a “grand slam” was possible owing to all four tournaments taking place (1905-14, 1920-39, 1946-85 and 1987-2019 for singles competition; fewer years for doubles, mixed doubles and wheelchair events), just seven other men have made a clean sweep of tennis’ four majors in a single year: Don Budge (1938 - singles), Ken McGregor and Frank Sedgman (1951 - doubles), Ken Fletcher (1963 - mixed doubles), Owen Davidson (1967 - mixed doubles), Stéphane Houdet (2014 - wheelchair doubles) and Dylan Alcott (2019 - quad doubles).

Thirteen different women have achieved a calendar-year “grand slam”: Maureen Connolly (1953 - singles), Maria Bueno (1960 - doubles), Margaret Court (1963 - mixed doubles; 1965 - mixed doubles; 1970 - singles), Martina Navratilova and Pam Shriver (1984 - doubles), Steffi Graf (1988 - singles), Martina Hingis (1998 - doubles), Esther Vergeer (2009 and 2011 - both wheelchair doubles), Jiske Griffioen (2013 - wheelchair doubles), Aniek van Koot (2013 and 2019 - both wheelchair doubles), Yui Kamiji and Jordanne Whiley (2014 - wheelchair doubles) and Diede de Groot (2019 - wheelchair doubles).
