Serena is more dominant than Federer but she would not take a game off of Roger. It's probably Chris Evert's intern writing that because she is into that type of nonsense.
She is only dominant because the best WTA players are useless mugs like Azarenka and Sharapova. Nose has to face Nadal, Djokovic and Murray - players who are not afraid of him and have the movement, defense and stamina to destroy him. Remind me who on WTA is a great mover, defender, has a good attacking game and is not a mental midget? Precisely. Serena is feasting on mugs, just like Nose would be without Nadal/Djoker/Mugray.
