Djokovic's playing surprises me and there maybe an element of selfishness on his part. His doctors advised him to rest for up to 10 days., but he is playing MC. Is this because:-
1. He will lose some points, allowing Andy to creep closer to his no1.
2. Knowing that Ferrer had withdrawn and by playing, Andy would be placed in Nadal's half.
3. He may yet withdraw, but the draw has already been made.
Djokovic often resorts to unacceptable gamesmanship. Witness his MTO before Andy's servicing for USO title and other cases when he used MTO to upset his opponent's play.
It does seem a bit odd, and I get the sense that he will be withdrawing, and I have had a grumble to myself that he should have done so before the draw. Then again, I'll be very happy if Andy makes it to the semi-finals. Of course, if that does happen and he loses to Rafa, I'll be annoyed again, lol.
