If he can't win against Roddick on clay, so against who he can?!
It's not like Federer is crushing Roddick today, 7:5 6:7 at the moment.
I think this shows what I already thought: It was a match on a high level, probably the best I've seen from Tommy for a while, but if Roddick plays and especially serves like he did in set 2 and 3 vs Tommy it's gonna be a tight match against anyone, even on clay or at least on a fast claycourt as we have in Madrid. And then it's about making the deciding points, Tommy didn't, but there are lots of opponents who couldn't have held their serves all the time like Roddick, the way Tommy played.
I'm much more concerned whether he can play at the same level again, if he does and gets a good draw, we can expect something from him in Roland Garros.
