Juan Martin Del Potro has defeated Roger Federer in four sets to advance to the Semifinals of the US Open at the Arthur Ashe stadium on Thursday. The Argentine no.24 seed beat the Swiss maestro 7-5 3-6 7-6 (10-8) 6-4. Del Potro will now face World no. 1 Rafael Nadal who earlier beat Russia’s Andrey Rublev. Del Potro had earlier defeated Roger Federer in the 2009 US Open finals to win the tournament that year.
Roger Federer and Rafael Nadal were favourites in this year’s US Open after Andy Murray pulled out of the grand slam two days before it began, while Djokovic and Wawrinka have shut down for injuries following their long term injuries.
