Well, Djokovic way too good there, it was a demolition job after they split the opening four games. He was majestic.
Aside from getting more first serves in and keeping his head in it a bit more in the second set I'm not sure what more he could have done out there tonight - the commentators were parroting on a bit about playing more aggressively as they tend to, but it's not something he can do at the drop of a hat obviously; committing himself to taking the ball earlier, stepping in more and avoiding his tendency to fall further and further back as the match wears on against the better players is still a complete work in progress and requires complete determination and belief from him to stick to the plan from beginning of match to end.
I sometimes think he doesn't have a whole lot of faith or comfort in the consistency of his shots when he tries to be more aggressive, which would be one reason why he's inconsistent in his approach to the bigger matches. Maybe he feels going for bigger shots would give away more matches than it would win him, I'm not sure. Staying in his comfort zone means he doesn't give too much away himself but I'd always prefer to see him take more control of the outcome against guys on the very top level.
And when Djokovic is putting him on the back foot from the first strike and barely giving him a thing to tee off on like he was tonight it's going to be heavy labour with not much reward, particularly if his serve isn't working that great, no matter how much he switches up his returns and pace. It's puts him under even more pressure. On the flip side, when the serve is working well he'll always have at least some chance in my opinion, but it still can't be relied on week-to-week even though when I look at it I think it should be even more of a weapon than it is now.
The Nadal match from Doha in 2009 will always be the benchmark of how he should play these matches in my opinion, but it might be a tall order to expect him to ever hit heights like that consistently (or even occasionally). We'll just have to wait and see but I'll always be very optimistic.
And with all that said, his draw in Cincinnati!
 Djokovic BYE
Harrison vs Chela
Isner vs Q
 Wawrinka vs Golubev
 Roddick vs Kohlschreiber
Ferrero vs Lopez
Dodig vs Q
 Monfils BYE
 Federer BYE
Del Potro vs Seppi
Bagdhatis vs Blake
 Troicki vs Fognini

Lost to Falla in R1 last year, that was a rough one.
Most likely to be Dodig, Roddick and then Djokovic again if he makes it that far this year. Fairly tricky, another QF showing would be excellent work
