The greatest champion in tennis history was slayed tonight by the forehand of a 20-year old from Argentina.
Juan Martin del Potro beat Roger Federer in five sets in the men's final at the U.S. Open tonight, 3-6, 7-6, 4-6, 7-6, 6-2.
The powerful forehand of del Potro was too much for Federer, who hit as many unforced errors as he did winners in an uncharacteristically sloppy match for the defending five-time champion.
