The reigning French Open champion said she feels more comfortable than she ever has on clay.
“I think when you win a Grand Slam on a surface, it would be pretty mean of me to say that I’m not comfortable on the surface,” she said. “It took me many years to get to the level of where I am today. It certainly didn’t happen overnight.”
The Russian, who could overtake Williams at the top of the rankings should she win the title, next faces Estonian Kaia Kanepi.
