Dolgo is too inconsistent, I'm not really sure. I remember him playing Murray during the French, and for a period he was literally unplayable. Then he turned to total shit. He's a true Jekyl and Hyde player, so I expect Nole to be too solid and come through whatever.
Nole in straight. I would be surprised if Dolgo manage to win a set. First of all Dolgo is very inconsistent, secondly he almost lost to Cipolla, played 5 sets with him. Yes he looked great against Ivo, but this didn´t say much, because Ivo´s game and Novak´s game are totally different stories in term of rallies, deffense, and skills. Dolgo is great guy with nice game for fans, but this is not his time to make upset, just couldn´t imagine him to be consistent great 4 sets at least- didn´ t expect him win in straight and he needs to 4 sets at least to serve great, move great, return great, his FS% must be at least in 50s if not 60s and i just can´t imagine all this will happen so most likely Nole will win in straight sets.
