Vegas were probably overestimating his name or his run at Brisbane. Or they made him a big favorite because they knew most people would know more about him and assume he was better than his opponent and bet on him accordingly. I certainly didn't think he was a clear favorite before the match.
All the announcers seem to be ignoring the fact that the ATP is separate from the ITF and the decision of the former to actually enforce time violations has no bearing on the latter. Somewhat surprising considering they publicly announced before the tournament that they had instructed umpires to be more lenient with time violations than they had been. Probably for the better in some regard. The ITF rules allow less time between points (20 vs. 25 seconds) and even with 25 seconds there were some situations in which a player couldn't help but get a violation (e.g. if he had broken a string). It would have been so much worse with just 20 seconds allowed.
Maybe quarters? Ferrer has played quite a few matches the last two weeks, wouldn't necessarily surprise me to see Nishikori beat him in R16 if that's how things shake out.
They'd actually play in the quarterfinals if both made it that far. I don't think fatigue will be a problem for Ferrer though, if that's what you're implying. He plays so many tournaments and playing in consecutive weeks rarely seems to faze him.
He'd face Tipsarevic in the R16 if the seeds hold.
Verdasco beats Goffin in five sets. Disappointing. Goffin was up two sets to one and a break in the fourth, but I can't really fault him too much. Verdasco is the naturally more aggressive player, dictating the entire match, and when he put together his whole game in the middle of the fourth set there wasn't a whole lot David could do. A very good match overall.
Novak playing decent. I have no idea as to what to expect against Harrison. For some reason, I keep getting the feeling that Harrison will give him some trouble... hopefully not.
You really do fret too much. Harrison plays a decent all-around game, but he isn't capable of threatening Djokovic at all. He doesn't generate much power off the ground and he plays so deep in the court he can't take away Nole's time at all.
