Fed has a chance still to do more, he wants the olympics and then the USO will be here before long.
He has a decent chance at year end #1 and going over 300 weeks at #1.
Fed's found a nice rhythm to his play now and should be in good shape for quite some time to come.
Again he's laid down the challenge to all comers if they dare enter the arena, there's only one result.
Of course I wouldn't mind a Del Potro forehand giving him a haircut but that will be discussed at a later time.
