Stefi Graf won her last Wimbledon title in 1996. Since then the women's singles titles have been won by Martina Hingis (Swiss), Venus Williams (USA), Serena Williams (USA), Maria Sharipova (Russian), Amélie Mauresmo (French), and Petra Kvitová (Czech) so she is definitely the last German to win it. Stefi married Andre Agassi (famous men's tennis player) on 22 October 2001, with only their mothers as witnesses.
Goran Ivanisevic notched up 212 aces during Wimbledon 2001.
