Was going to put my money on Del Potro but what a tough draw for him ... he could have to beat Hass, Djoko, Murray and Nadal to win it all
I am actually surprised he is "only" +1100 (pinny) to win!
If he would be +150 (average) against the big three, you would have already +1500 return! And I would expect him closer to +200 against Djoko (he was +600 at Wimbledon semi).
Dream draw for Nadal, even if Isner in eighteen is not a gift ... but I would not touch him at +200, he has never been a lock at US Open.
Any thought?
