Steffi Graf beat Gabriela Sabatini, left, in the finals of both the US Open and the Olympics in 1988.

On this day in 1988, the Summer Olympics opened in Seoul, South Korea, and, for the first time since 1924, tennis would be played at the Games. A 19-year-old Steffi Graf stole the show. The West German, who already had won the Australian Open, French Open, Wimbledon and U.S. Open that year, defeated Gabriela Sabatini 6-3, 6-3 in the gold-medal match to win the calendar year Golden Slam. She remains the only human to accomplish the feat. Graf retired in 1999 and was inducted into the International Tennis Hall of Fame in 2004. She would be joined in the Hall by her husband, Andre Agassi, in 2011.
