If Fed is in the zone he can win in a dominant fashion. I was re-watching Fed begaling Djokovic in Cincy and it was a level of tennis that I haven't seen since 2006 (or WTF 2011). Yes, Cincy is a faster surface but you never know exactly what will happen when these two play. Fed is one of the few guys that can hit a lot of winners past Djokovic's awesome defense. Fed also servered amazingly well in Cincy.
