That 6-2 set Agassi played against Federer in the 2005 US Open Final was the best set Agassi has played in a long long time. Did you see how hard Agassi was crunching the forehand? Very very powerful stuff that Federer could do absolutely nothing about! And Federer was actually playing very very well himself and getting in 80% of 1st serves. Agassi was executing the game-plan that he earlier revealed in the press conference - hit the ball into the corner and in the corner again and again and again. It kept Federer running away from the baseline like a swiss miss!
