I have to take a bit of time here to rant about the crowd for the final. Now, no doubt they were waiting a long time for the final to start because of the rain, and probably many were drunk by the start of the final.
The Ashe crowd was disgusting and stupid. If they really wanted their man Federer to win,
and been smart, they should have been totally silent for all of Novak's shots, like a church full of people listening to the priest. Good shot, great shot, bad shot, fault, double fault, no matter.
This is the correct strategy for a crowd who wants their man to beat Nole.for a player of Novak's psyche. It is respectful but damning at the same time. Being quiet when he makes bad shots is respectful and only common tennis etiquette.
But the thing that hurts Nole the worst, is when there is no applause, nothing, just silence for his great shots and efforts. We've seen evidence of this many times. When he feels under appreciated, it is then he tries to lift the crowd up, lifting his arms in the hope of getting deserved appreciation and adulation. If all he receives is silence, he can't understand and it devastates him. It is the worst thing for him. It completely shatters him. There is nothing worse for him than to be totally ignored.
But instead, the ignorant and largely inebriated crowd cheered or mocked his bad shots, maybe some even used bad language. This has the opposite effect on a man like Novak. It just spurs him on in defiance. It makes him furious, stronger and he hits back even harder.
So for the crowd of Federer fans who carried out this behavior, you can only blame yourselves for goading Novak to a level where he refused to give up on shots, running everything down and making the great Federer attempt winner after winner, only to see them amazingly come back in his face. When attacked, Nole defended, defended, and then attacked back. What could Federer do in the face of that? Due to Nole's extreme effort and the slower humid night conditions, Federer was hitting lines and still couldn't get the ball past Novak. His only chance was to come to the net even more, but he wasn't quite brave enough to do it in the crucial points. He knows it now, but too late for him. Fortune favors the bravest!
THIS IS SPARTAAA! (Guess who that is next to Novak)
