2009 US Open: Del Potro defeats Federer in a classic 5-set showdown.

Due to the bad weather conditions, the 2009 US Open mens final between Juan Martin Del Potro and Roger Federer was played today.

The fans gathered at Arthur Ashe stadium were in for a five set showdown that lasted just over four hours. At the end, Juan Martin Del Potro took advantage of the play with his formidable and powerful forehand and won by 3-6, 7-6 (7-5), 4-6, 7-6 (7-4) and 6-2.

The momentum shifted a couple of times during this wonderful match. Federer at first, exploited a nervous Del Potro who really needed some time to get into this match. But once his gears got rolling and his forehand was adjusted to kill mode, Federer became a mere spectator so many times.

But we also have to give some credit to the great champion that is Roger Federer. His grand slam experience allowed him to hang in there and even steal the third set away from Del Potro.

But the fire and intensity of Del Potro was too much later on. After a disputed fourth set decided at the tie breaker, the dominance of his forehand made the difference.

Congratulations to Juan Manuel Del Potro for his very first grand slam championship at these 2009 US Open championships.
