Yeah, unfortunately it seems like Rafa's grinding style is finally catching up with him. We all knew it would happen eventually. That said, I still think he's got one at least one more trademark Nadal comeback left in the tank. He's in the process of changing his racquet and hopefully some tactical changes as well. I wouldn't write him off just yet.
As for Fed, I think it's Wimbledon or nothing at this point, especially with his newly discovered serve and volley game since Edberg came aboard. I thought he had it last year, especially after forcing that 5th set. Alas...
While Murray is playing the best tennis of career outside his '12-'13 run, he's still Andy Murray. And that means he will almost always fold like a chair when playing the Big 3 in a major. I will say I was shocked he actually forced a 5th set after going down 0-2 in the French semis, but he predictably folded in the 5th. Outside of that '12-'13 run he still doesn't have the answers against the Big 3.
I think of anyone on the tour right now Stan actually presents the most problems for Djoker. Stan's flat and hard ground strokes (from both sides) are just brutal, as we saw at Roland Garros. They've played 5 times in majors the last few years and the first 4 meeting were all 5 set epics. When they play it's must see tennis. Can't wait for Wimby.
Ok tennis rant over.
