Re: Is Roger saving energy or has he lost a little confidence?
My heart's no longer in this, now that Nadal is out 
I predict Murray will win, but his match against Dolgopolov showcased some pretty lacklustre play on his part; I believe it's going to be a tough match. But yeah, Murray has what he needs to beat Ferrer.
As for Djokovic, it looks pretty clear to me that he's got Fed's number, and will be able to beat him handily. Let's go, Nole!
