I basically only watched the first set of my recording. The way he lost that set, was painful to watch. As Neely mentioned, a DF and then those UEs on both wings, especially an easy fh put-away. He served so well in the earlier games and should have won the set, since he had bps...
I regained some hope, when I saw how long that last game in the 2nd set took, but it wasn't meant to be.
Well, Wawrinka is in pretty good form, but you could see the difference to Federer, who is clearly the better server. Kiefer, at least in the first set, managed to return a lot of serves.
Kiefer had two very weeks in Madrid and Basle, let's not forget about that.
