If Fed is going to win another major, he may never have a better opportunity. It's his best surface, he has a favorable draw into the semis, and he's looked really good so far. Beating both Novak AND Nadal is a tall order, but beating one is feasible, albeit still difficult.
If Fed gets to the finals at Wimby, he actually retakes the #1 ranking. That is significant, because he has held the #1 ranking exactly one week fewer than Pete Sampras, who has the record. Roger wants this desperately. He has the heart of a champion and one of the most beautiful games in the sport's history. It will be interesting to see how he responds.
