Three women to win Grand Slam in the same calendar year

The “Grand Slam” is the winning of all four Major tournaments in a single year; however, it has also been used for many years now to refer to any of the major tournaments. Though technically incorrect, since a “Grand Slam” is a collective achievement, rather than a single event, this term is now used by the major tournaments themselves.

Three people who won GrandSlam in Women’s Singles (all four Major tournaments) in a single calendar year:

• Maureen Connolly Brinker (1953)
• 6 consecutive major titles, 1952 Wimbledon through the 1953 U.S. Championships.

• Margaret Court (1970)
• 6 consecutive major titles, 1969 US Open through the 1971 Australian Open

• Steffi Graf (1988)
• 5 consecutive major titles, 1988 Australian Open through the 1989 Australian Open
• Graf also won the Olympic gold medal in 1988 (The “Golden” Grand Slam)

There were also three such occurrences in Men’s Singles: Don Budge in 1938 and Rod Laver  in 1962 and 1969.
