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.
Not really that surprising for Djokovic and Federer since Olympics are only once every four year. I’m always more surprised that Nadal doesn’t have even one ATP Final.
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).
