Svetlana Kuznetsova, who defeated world No. 3 Agnieszka Radwanska at Roland Garros on Friday, said she made a mistake when she moved her training base out of Spain and back to Russia. Kuznetsova has not been a force at the majors since she won Roland Garros in 2009.

"I try to play more forehands, I try to dictate, I play more speed," she said. "This is the game I was playing when I won [2004] U.S. Open and I won the French Open, when I won Miami. And start to be very ordinary on the court in my game, the tennis that other girls play and other girls like. I have some advantages, which I have not been using. Coming back, for example, to Moscow to train, it was right thing for my soul, to my feelings inside, but changing my tennis from Spanish ways to another way, that was wrong for me. I had great coaches, everybody I appreciate a lot, and they brought a lot to me, but I need something else. I need a little bit back, my spin game."
