Natasha Zvereva of Russia in 1988. This was the year Graf won her GOlden Grand Slam, all 4 majors plus the Olympic Gold.
Natasha is famous for saying early in her career to the Russian government "i want my prize money". RG was withholding a lot of it. NZ went on to become a top doubles player.
After the match in Paris in 1988 Steffi Graf apoligised due to the match was so short. About 33 minutes.
Somebody said the best thing about the match was the rain delay in the middle of it.
Steffi Graf is the last person, male or female to win the GRand Slam, Australian Open, French Open, Wimbledon, and US open in the same calendar year.
Serena Williams did it in a non-calendar year.
hope this helps...
Also it;s GRAF, not GRAFF. one "f".
it;s not spelled like Graff Diamonds in New York, the store...
