One week into the US Open and it's definitely shaping up as one of the more unpredictable slams, at this moment the favourites for the titles seem to be Djokovic and Serena.
MEN'S DRAW SECTION 3 & 4
The biggest shock for me was Del Potro losing to Simon. Whilst I knew Simon would provide a tough challenge I was really expecting to see a Del Potro/Murray QF. Simon will now face Isner and the winner of that will play Andy Murray who stormed past Feliciano Lopez unlike his previous match against Robin Haase. Besides Fish and Isner Donald Young and Andy Roddick are flying the flag for Americans in the 4th Round but I doubt Young has a chance against Murray whilst Roddick is on the back foot against Ferrer. Finally Nadal beat Nalbandian in a tough three sets but will next face Gilles Muller, which should be easier.
WOMEN'S DRAW SECTION 3 & 4
So Kerber will face Pennetta in one QF. I have full faith that Pennetta will be able to make her first US Open SF and be a contender for the finals. In the other QF Sam Stosur will face Vera Zvonareva. Zvonareva has looked the more prepared of the two beating Sabine Lisicki in two easy sets whilst Stosur has had two tough matches against Petrova and Kirilenko already, can she face another Russian test?
BIGGEST LOSS OF THE DAY Juan Martin Del Potro
