Now Isner scares me slightly, If this was 3rd round I'd be like Andy will win, but cos its the dreaded 4th round I am more nervous.
Plus Isner is 8-0 in match wins in 2010 he'll be coming in with alot of confidence.
I'm slightly on edge but I'm also conscious that Isner is now VERY tired.
I don't think he has much left - I think if Monfils had been able to get that 4th set today Isner would have folded like a cheap tent in the fifth.
So I think Andy needs to play extraordinarily badly to lose. But that is still possible - Andy is still capable of these banana skin performances. But it would have to be a shocker, because Isner on paper has the sort of game that Andy normally gobbles up - big but readable serve that he can return regularly, game based pretty much on power forehand and some volleying. Andy normally makes players like this look very ordinary.
I think there's good reason for optimism here, but Isner should not be underestimated either.
