I am SURE that Mary can at least reach quarter !
Loit doesn't play her best, and even if it was the case, i know that Mary is a better player !
Then, Ruano could be a dangerous opponent because Mary is ALWAYS injured against her, and i'm afraid about the "Ruano malediction" : in 2003, mary was to play Ruano at Amelia Island, but Mary gave up before the match ... 2 or 3 weeks later, in berlin, Mary retired because of injuries ! This year at Wimbledon, mary plays the match, but she wasn't as good as usual, because of her hand ... So, a difficult match is Mary is injured, but if she's in shape, no matter and an easy match !
In third, Sharapova ... That's a very tought opponent, hard to play ... but Maria has not play her best since her WImbledon victory (she lost against Mashona Washington this week) whereas Mary shines with a good fed cup match and great Olympics tournament. So i'm reallu optimistic about this match.
Fourth round, Kuznetsova i think ... Kuznetsova doesn't play her best, she lost against Razzano in Englan, so i think all can be possible. But i think that Kuznetsova is the best player that Mary will have to beat to reach quarters.
Then, probably and unfortunately Henin-Hardennes ! Hmm, i would really enjoy such a match and i'm wainting for the revenge of the Athens quarters
But first, Loit ! Go Mary, and, please, try to be more consistant than you were in England, just after having won S hertogenbosh ... Because often, Mary plays great, and loses soon after ! (Open gaz de france and Anvers, S hertogenbosch and Wimbledon ... so i don't want to have to write later olympic games and Flushing Meadows) ...
In all case, Go Mary
