Mardy Fish systematically took down ATP #2 Rafael Nadal 63 64 today in the Cincinnati Master Series quarterfinal. It was the first time in six tries Mardy Fish has been able to defeat Nadal, who seemed to struggle mightily more because of Fish's consistency, big serve, serve & volley attacks than the fatigue factor from Nadal playing the Verdasco marathon yesterday and a doubles match with Marc Lopez vs. Bhupathi/Paes.Nadal gave it his all, as he always does, but he came up short today. He appeared super intense in the warm-up, his fierce body language indicated he was extremely-motivated to test himself against the streaking Fish, who is, aside from Djokovic, perhaps the hottest player on the ATP tour now.There were many spectacular points by both players, especially by Fish, who staved off some key break points in the opening game of the match. Fish, who has not been broken all week, got better as the match went on. He never showed any hints of pressure or faltering in the conclusion. Nadal had a break point in the second set 4-3 game but he weakly netted a second serve. Fish held, then Nadal held, and when Fish served for the match, he built a 40-love head and then end the show in style with a forehand crosscourt winner. Arms raised and a joyous smile on his face, you instantly knew how important this win was. Mardy Fish is now a leading contender to win the U.S. Open, along with Djokovic, Federer, Nadal and Murray, who he will meet in tomorrow's semi. Fish has beaten Murray the last three times they have played.
