Del Potro dethrones Federer in US open epic

US OPEN champion Juan Martin del Potro will not be complacent in his search for future grand slam glory, despite landing his first title with a defeat of Roger Federer.

The 20-year-old from Argentina scored one of the upsets of the year at Flushing Meadows when he beat world number one and five-time defending champion Federer in five sets to claim the US Open men’s singles title in his first grand slam final.

It was del Potro’s first victory over Federer in seven attempts, denying the Swiss star a 16th grand slam title, ending a 40-match winning streak at the tournament and preventing him from becoming the first man since Bill Tilden in the 1920s to win six US national championships in a row.
