For a tennis player, winning the "Grand Slam" involves winning four tournaments in the same calendar year: the Australian Open, French Open, U.S. Open, and Wimbledon. Only a handful of tennis players have accomplished this extraordinary feat, including Maureen Connolly (1953), Margaret Smith Court (1970), Steffi Graf (1988), Don Budge (1938), and Rod Laver (1962 & 1969) who managed to win the Grand Slam TWICE!
