It sure could but, let's wait and see what happens. If he has the same start as today I don't know.
To beat Denko, one of two things have to happen:
--Fed completely ups his level and plays like past years -OR-
--Denko completely chokes.
I don't see Fed winning more than 5 or 6 games with his current state of groundstrokes, return of serve, power, movement, big zit, etc. etc.
