Cilic is obviously the popular play by those who are following the Rafa illness from earlier this year. Problem I see with that is that Cilic just played a grueling five setter, so any perceived edge from the illness angle is negated by that. And let's say this, Rafa looked sluggish ... and won in straight sets with two of the sets pretty routine.
Dologpolov - who the F knows. I still don't trust this kid. Beating Tsonga who is not fully back in match shape doesn't really tell me anything. Does he have the game to beat Soderling? Maybe at his best, but Soderling has looked tremendous so far.
Melzer - No chance from what I have seen from Murray. Murray & Soderling to me have played the best this week.
Raonic - Needs Ferrer to have a horrible serving day like Youzhny did where he offers back a lot of break opps. His serve will give him a chance likely to stay in sets, but Youzhny broke him four times. Ferrer is one of the best defenders in the game. I think Raonic gets a set, maybe pushes it to five if Ferrer is off a little.
No way in hell Murray or Soderling loses. Raonic is the best chance of an upset as his serve can keep it close and allow him to set up crucial points and get good - or get lucky; but Ferrer will have to return and serve really badly for it to happen.
As for Cilic, well I have a future on him but let's say I'm not hopeful.
