No you can't. They don't own Nadal like Blake does. Hewitt could not beat this Nadal, neither Haas. Gonzo lost to Haas so that's another story.
like conita said a post above me: blake's got a pretty bad record against most of the guys in the draw. i don't think he would've gone all the way to the final in the first place. and beating nadal in his (blake's) actual shape is another thing. he's not really that dominating anymore as he was last year, making loads of unforced errors and sometimes not seeming really focussed. he should've won a masters last year, these days there's no way he will get a title in north america.
well, if he's lucky enough he may be able to get one at paris or madrid at the end of year, given that nadal, federer and many others probably won't be around. clay's pretty much ruled out anyways.
