Why do you say that - Filip is a feast or famine type of player - when he is hot, he's hot.
I watched the Tiago win in Rolland Garros and he out played him; the guy wasn't injured at all, just "using tricks."
Well, I would be happy to hear that Filip destroyed an in-form Aarts, but it just seems to me that someone like Aarts should be able to win a few more points on serve, whoever he is playing against. He won just 30% of 1st serves - that really is unnaturally bad.
But I note that he lost his last match - 0-6, 1-6 (against someone ranked 705).
