No player has been more successful in the Open Era (since 1968). In doing so, she surpassed Steffi Graf, the previous record holder in the Open Era, with a win. However, she could not reach Graf’s Grand Slam, which she even expanded into a Golden Slam by winning the Olympic gold medal at the 1988 Games in Seoul. She won four Grand Slams in a row twice, but not in one calendar year. In the tennis world, this success is now dubbed the Serena Slam.
