Open Era's Greatest Claycourter

Ok here's another one.

Who are the top 10 dirtballers of the Open Era?

My list is:

Chris Evert
Steffi Graf
Monica Seles
Martina Navratilova
Aranxta Sanchez-Vicario
Conchita Martinez
Gabriela Sabatini
Martina Hingis
Justine Henin-Hardenne
Serena Williams

Ummm. . .. . Chris Evert kinda has this sewn up.

7(!) French Opens....125-match winning streak on clay...
