Well that was the best Murray has played since Wimbledon last year, really promising to see him hitting the ball so well again.
However his serving is still a problem, it is improving, but not good enough. 63% first serves in, needs to be higher 60's to beat Djokovic/Nadal/Federer; and 39% points won on second serve against that opponent is actually quite worrying, he probably can't do much about that at this stage (his 2nd serve will currently always be a weakness), so getting that 1st serve in % up to the high 60's or above is key I think next week!
Oh and anyone who doesn't rate tennis should have seen the Dimitrov vs Dolgopolov match yesterday, especially the first 3 sets were remarkable tennis, with amazing shot making. If only all tennis was this exciting. And if Dimitrov plays that well against Murray on wednesday (if they both get through), it's going to be a very close match
