Watch Juan Martin del Potro’s epic reaction after upsetting Roger Federer at US Open

Roger Federer rarely loses U.S. Open matches played at night, but Juan Martin del Potro shocked the world and defeated him quite easily on Wednesday night.

Federer was previously 34-1 in U.S. Open night matches heading into the affair, with his only loss coming against Tomas Berdych in 2012.

But he didn’t have his best stuff on Wednesday, and the usually-consistent Federer missed some ridiculously easy shots that he rarely blows. And del Potro capitalized big-time. He used his wicked forehand to have Federer running all night, and emerged victorious 7-5, 3-6, 7-6, 6-4.

ESPN captured a great moment after the match, while del Potro was celebrating in front of the many fans that came out to support him. Check it out.

What a moment for JMDP. He’ll now face Rafa Nadal in the semifinal round.
