Fed will know Andy will be tired
But will he?
Andy only played a set and a half today - probably no more than he would have done in practice in any case - and it didn't seem that emotionally draining. No fifth set, no tie breaks, and he seemed in control at all times. Nothing like the Gasquet match, certainly.
Easy to forget the pressure on Federer too. After 5 years of winning slam after slam after slam all he's won this year has been Estoril and Halle and he's recently lost the no 1 spot with more young pretenders also coming through. Chances are fast running out to break Sampras' record, and he knows it.
I make Andy slight favourite in this one. Andy in 4, and if it does go to a fifth then Andy will win that.
