World No. 3 Vera Zvonareva, who is active in promoting equality for women, says that comparing male and female players is absurd. "I think it is a funny thing to do, but overall I think it is a little bit stupid to compare men to women in sport," she said. "We just know there are physiological differences. I never heard [sprinter] Usain Bolt say, Come on, ‘I can run better than Marion Jones. She cannot run.’ I think it's a little bit stupid to compare female tennis players to male tennis players, especially when guys start comparing themselves. If they want to go and compete against girls, of course they can go and do it. But I think we have to be respectful to each other. We all work very hard and try to do our best. If you look at any sport, as long as you have personalities in sport and as long as the sport brings excitement to the public, I think it is great."—Matthew Cronin
