I've seen close to zero matches this week, the time zone is just as uncomfortable as it gets, and judging by the results both guys are in good form.
H2H is 2-1 Lopez (1-1 on hard).
Of course I'll root for Flo, and say he'll win in 3.
I saw Lopez against Bogomolov and today against Berdych and I must say that is real joke that this man is in 1/4-final of an masters series tournament. Against Bogo he was awfull and I still don't know how he manage to win at the end (tons of UE's, 14 double faults, no backhand, no 1st serve etc...) Against Berdshit things looks better, but still he can say "thank you" to Berdych for this win. Berdych was on much lower level in todays match than in match against Stepanek and last week in Beijing, and FLO had been simply great against Nalbandian and specially today against Rafa.
