Tennis fans know that Chris Evert holds the greatest clay court record of all time--among women and men. Evert won 125 consecutive matches on clay, and she did it using a wooden racquet. Not everyone knows who broke her incredible streak, though. It was Tracy Austin, who defeated her 6-4, 2-6, 7-6 in the semifinals of the Italian Open in 1979. Evert did not lose another match on clay until the 1981 French Open, which means that during a 7-year period, she was 197-1 on clay courts.
Evert--who did not even play at Roland Garros in 1976, 1977 and 1978--won seven French Open titles, and there is no doubt she would have won at least one more had she played every year. I think three more is a more accurate guess, since she remained undefeated on clay and was number one in the world during that period.
All hail the Queen!
