I think it is an advantage and a disadvantage.
Look, Roger is 29. He needs all the rest he can get.
But, he might be a little rusty, and he's playing Ferrer/Davydenko, a tough match despite Roger's h2h record against them.
I mean, if I was Fed, I would have wanted to play this match considering how little match play I got vs. Istomin.
Still, though, it's Federer, he'll be fine
I hope Kohli can get himself ready for the USO. He really impressed me vs. Nadal last week.
