Yesterday I was watching the match between Dokic and Bartoli, and one of the commentators mentioned that they'd seen Marion having an intense gym session just hours before a tournament final last year. I wonder if this kind of tactic would work for Sam, as a way of exhausting the nerves away. Probably wouldn't be a good thing to test out first round of a grand slam though.
Marion is a very impressive woman. I have no idea where on earth she gets her stamina from. Personally I quite enjoy watching her play, simply because she's so damn interesting
