On Monday, Aug. 30, Novak Djokovic begins his quest to win the US Open and thus the Grand Slam — holding all four Slams (including the Australian and French Opens and Wimbledon) in one calendar year. Only two other men have done it (Don Budge in 1938 and Rod Laver in ’62 and ’69), along with three women (Maureen Connelly in ’53, Margaret Court in ’70 and Steffi Graf in 1988, the year after Djokovic was born). Graf remains the only person to win the Golden Slam — the Grand Slam and the Olympic gold medal that year.
