Sir Alex, aside from having Nadal in his quarter or half, Djokovic has the toughest draw. But he might get a bit fortunate as Stan is playing in the Portugal final today, and has no bye to rest, probably playing Tuesday. He could be tuckered out by the time he has to play Nole, assuming Nole gets by Grigor.
Ferrer got the fuzzy end of the lollipop with Nadal in his quarter.
Federer has a good chance to make the semis if he returns from his 2 month layoff with some good form.
Murray would have a great draw if it were hard court. But it's clay, so there is probably no easy draw for him.
I wouldn't be surprised to see Daniel Gimeno-Traver make it out of his section to face Federer.
Sharapova said the new red clay courts are very slow and deep from the cold wet weather Madrid had recently.
But the forecast calls for sunny and warm weather during the next few days, so I expect conditions to get better.
