2009 US Open champion will not repeat as champion in New York after losing in the third round on Sunday. Del Potro lost to Giles Simon, of France, the no. 12 seed, 4-6, 7-6(5), 6-2, 7-6(3) in a grueling third-round match on Louis Armstrong Stadium.
Simon is known to be a passive baseliner but he hit 11 more winners than del Potro, while hitting 29 fewer unforced errors to prevail in three hours and 57 minutes, reaching the round of 16 in New York for the first time in his sixth appearance.
"I was break up, 3-2 [in the fourth set], and then I started to play a little bit shaky. Was hitting harder and harder every time," said Simon. "Finally I started to be tired and it was really hard to play at the end of the match.
It was very good to finish in four sets." "I knew I had to be a little bit more aggressive," assessed Simon. "That's what I tried to do. I think I played a good serve and volley. Then I hit a winner also, then a good first serve.
I managed to do it. It was a very good idea." "He's a fighter, It's very hard make a winner playing against Simon," said del Potro. "I tried until the end, but I played [at a] lower level in the tie-breaks.
He took the chance and he closed the match." Simon avenged his 2008 third-round loss to del Potro at the Open, when the Argentine prevailed in a five-set clash, as well as a straight sets loss in the third round of Wimbledon this season.
In the fourth round, Simon will take on the winner 28th-seeded John Isner for a spot in the last eight.
