Juan Martin del Potro claimed an unlikely victory over 19-time Grand Slam champion Roger Federer at the US Open last night. The Argentinian has now denied Federer the chance to take on long-term rival Rafael Nadal in the semi-finals, and the 36-year-old admitted that he ‘didn’t deserve’ to progress.

There are very few tennis players that have been able to rise to the challenge of beating the great Roger Federer over the years, but once again Juan Martin del Potro has managed to get the edge over the Swiss Maestro at the US Open. Del Potro famously denied Federer his sixth US Open title in 2009, ending an impressive 40 match winning streak.

Del Potro – no doubt still rattled from his thrilling win over Dominic Thiem on Monday, saved four set points in the third set last night, before claiming an eventual 7-5 3-6 7-6 (10-8) 6-4 victory.

Federer said of his tournament progress: “In some ways I’m actually happy I made the quarters, so I’m not disappointed, because it’s been a good run this year already. Unfortunately I ran into a guy who was better than me today.

“Juan Martin deserves it more. I feel I have no place in the semis and he will have a better chance to beat Rafa.”

Del Potro is set to take on Rafael Nadal tomorrow.
