All I saw following the SB was Hewitt breaking Lu in the first game of the match and then that being the only break of the first set. Then Hewitt breaking Lu at 1-1 in the 2nd with Lu breaking back at 3-4* I believe
If Hewitt were to replicate his form from Australia then I'd give him a good shot against Roddick, given his form also. But if he plays at the level from San Jose then he won't beat Roddick.. IF he manages to get past Mannarino.
Got the result here, that's all that matters... Mannarino has been playing well this year and will be a bigger test but I expect Rusty to find a way. Then if he does face Duck, well he has a shot like Stevo said and they had a tough 3 setter a couple of years ago here in the semis..
