Hes already going to do better at Cincinatti.
Last year Fed made QF in Canada and W Cinci: 1180 points
This year he made the final in Canada and for now has reached SF in Cinci: 960 points.
Roger is still defending pre-USO HC points.
Last year, Rafa made QF in Canada and SF in Cinci: 540 points
This year, he has achieved the same results, albeit the other way around: 540 points.
So Rafa has defended his points, while Fed won't if he loses today (if he beats Baghdatis but loses the final, he'll make 1200 points, which is about the same as last year's result; if he wins Cinci, he'll make 1600 points, which will aloow him to cut the difference with Rafa by 420 points). He may well do it, but we'll have to wait till tomorow night.
He will probably go further than Nadal at WTF because Nadal always sucks there.
I was aware that 2 SF out of 3 appearances cannot be described as brilliant, but 'sucks'? Well, if you say so...
Back on topic, of course Fed can do it, the question is not can he but will he.
