She would struggle to win points, let alone games. I would love to see Rafa or Djoker take on Serena on clay, that would be really funny to see.
She would struggle to win points which required trading off the ground, that may be true (in fact I agree that it is). However, uniquely for a female tennis player, Williams has a first serve big enough to ace or soften up a point against any returner. A few first serves in a row, maybe one mistake (it's not like the male players are perfect), and that's a game. It's easily imaginable. To me, it's bizarre that some people think this is out of the question.
That's it. She aced him twice in a match. Yeah, that will win her games. Even Wozniacki aced Fish, so?
Twice in one game, gets you halfway there. Only need two more good first serves and competent follow up and you have a game. Is it out of the question? If you really think so, why?
Lets consider that Williams aced an opponent over 20 times in a two set match in Wimbledon last year. If you watch any mixed doubles you'll know that whilst it's considerably easier to hit unreturnable serves against women, the difference is not such as to make comparison irrelevant. Men do not ace women all the time, and women hit unreturnable serves against men. It Happens. This is undeniable. 120mph serves which hit the lines don't get 'easily returned' as someone laughably suggested earlier in this thread. A good serving game is all it takes. Which part of this idea do you disagree with?
