Okay, so Raonic is next. Very tough opponent as Andy will have 0 luxury to lose his serve and still win. And that's a very big task to ask from Andy right now to serve confidently and go for easy holds. In fact, he is constantly on the verge of losing his serves and he often does and that's what in particular puts him in great trouble initially. And holding serve comfortably is Raonic's main strength and it almost never lets him down. You can see the key problem there now.
So what to expect? I think Andy is perfectly capable of raising his level but his form is nowhere near that. Even if his will/desire is there, he is unable to click it. But things gotta change at some point and one of the players should really does that click for him. Let's see.
Now that Nadal is out and if he gets past Raonic, then may be he can be up for a revenge against Federer but more importantly, he could very well go for the title. Asking a lot much I know but then reality is stranger than fiction!
One step at a time though. Come on, Andy! You can do it.
