I'm still processing Marat Safin's upset of Novak Djokovic earlier today. Probably not a total surprise that a former U.S. and Australian Open champ turned out to be capable of such a strong result. But Safin's play in recent years has been so sporadic, it was hard to see this coming. It will be interesting to see how far he advances now. Certainly Roger Federer won't be sad to see the Djoker, who beat him in the semis in Melbourne and again was in the same half of the draw, bounced from the tournament.
