PARIS, June 4 (Reuters) - Juan Martin Del Potro stormed into the French Open quarter-finals with a convincing 6-4 6-4 6-4 defeat of the big-serving American John Isner on Monday.
Del Potro, regarded as one of the biggest threats to 10-time champion Rafa Nadal at Roland Garros, broke three times and held serve throughout to set up a meeting with either Croatian third seed Marin Cilic or Italian Fabio Fognini.
“I returned very well, it was the key to the match and I broke three times, I also played well on the important points,” said Del Potro, who throughout the match heard parts of the crowd chant ‘USA, USA!”
“I love playing here in the USA, USA!,” he joked.
“We both played good tennis today. It is so special to get to the quarter-finals here, I’m having great days in Paris and I’d like to stay a few more days.” (Reporting by Julien Pretot; Editing by Larry King)
