Only three players completed boxed set - Doris Hart, Margaret Court and Martina Navratilova.
Honorable mention: If player wins all 4 majors, olympic gold and year-end tournament in same year, it’s called super slam. In 1988, Steffi Graf achived a non-calendar year super slam. In 2021, Diede de Groot achived this feat in women’s wheelchair singles.
Yeah. Novak clearly cares about the Olympics, but people who hold that against Novak in the GOAT debate seem to forget that Nadal has 0 finals wins (which happen every single year).
