I am also glad he went through. I only watched the 3rd set, he played well during the tiebreak, as usual. I dosed off right after the set was over because of fatigue
The match was over when I woke up
Jo did seem to have trouble getting around the court. Also, Golubev made some shots look so easy! By the way, I don't think Karlovic is a huge threat, I have this impresion of him as the guy who can lose to pretty much anyone. But then again, top 50players ranked outside of top 20 all fall into this category.
I hope Jo can beat Bolelli without too much trouble. He needs to improve his returning skills eventually.
