Re: 17-1 on clay this year, is she "Rafinara Nadafina"?
Simply put, no. Nadal's game is tailor made for clay. He has a heavy, heavy topspin lefty forehand that forces righty opponents to hit super high backhands on the run--physically one of the hardest shots in tennis. The clay exasperates the high bounce of his topspin and also rewards him more for his unusual speed, since he has even more time to get to and then set up his shots, making it near impossible for his opponents to hit winners. Clay has also traditionally masked his big weakness--the serve (particularly the second) since, again, it is harder to hit winning shots on clay, so having a big serve doesn't matter as much (and quick players like Nadal can get to a lot of the second serve returns that would be winners on other surfaces).
Dinara doesn't even move particularly great on the clay. She is comfortable, to be sure, but her game should be better suited for fast surfaces that reward her power.
