Steffi Graf's 22 Grand Slam Championship Points

Steffi Graf's 22 Grand Slam singles titles put her second on the list of major wins in the female competition since the introduction of the Open Era in 1968 and is third all-time behind Margaret Court (24) and Serena Williams (23). In 1988, she became the first and only tennis player (male or female) to achieve the Golden Slam by winning all four Grand Slam singles titles and the Olympic gold medal in the same calendar year. Furthermore, she is the only tennis player to have won each Grand Slam tournament at least four times. Graf was ranked world No. 1 by the WTA for a record 377 total weeks — the longest period for which any player, male or female, has held the number-one ranking since the WTA and the ATP began issuing rankings.
