Are you sure about that? I don't think there has ever been a tennis match played under normal rules where a top pro woman has beaten a similarly ranked pro man. In the most recent such major exhibition, Karsten Braasch easily defeated both Williams sisters even though he was only ranked #203. The difference in speed and power is enormous, to the extend that at elite levels women and men are playing totally different games.
