Did you know:
the French Open, the Australian Open, Wimbledon and the US Open make up the four events collectively known as the Grand Slam.
Only five players have won the Grand Slam (winning all 4 events in the same calendar year) since its inception 70 years ago.
Donald Budge (1938) and Rod Laver (1962 and 1969) are the only men to have achieved the feat. Margaret Court (1970), Maureen Connolly (1953) and Steffi Graf (1988) the only women to do so.
