I am very glad that Julia held on, but that's pretty scary giving up a 6-0 5-1 lead like that. At least she held on - it could have been humiliating if Lucie had won that tiebreak!
Best of luck tomorrow in the SF - break that string of SF losses!
Also I am glad Julia's ranking will likely be enough to get in to the US Open - now if only she could NOT draw a seeded player this time in the first round. (which she has 5 out of the 6 Grand Slams she's played!)
