even tho Rogi has never played Ruben Ramirez-Hidalgo before, he SHOULD win this match... RRH has not yet won a title and he's about 30 yrs old... nevertheless, my approach is one match at a time...
Isn't he like an ATP version of what's her name the little pusher on the wta, she's really fit and quick but can't generate much pace at all, the tiny spaniard what's her name. Even Hingis looked like a power hitter when they faced each other.
(Medina Garrigues, I just looked her name up) He might bother Federer if he's having trouble finding his range and rhythm initially which seems to be the case for all his first round now a days.
He'l push the ball around and retrieve a lot but I don't think he should really impose himself on this match, I think this match is more about what Federer does or fails to do.
