"I'm going to feel like I beat myself," Federer said. "It was up to me to make the difference and I just couldn't,” said Roger Federer. (AP)

"I self-destructed, which is really disappointing. When things came to the crunch I just couldn't do it. It's frustrating," said very upset Federer. (AP)

Federer's failure, which came on the heels of a shock second-round Wimbledon exit, thwarted a potential quarter-final match with 12-time Grand Slam winner Rafael Nadal in what would have been their first meeting on the New York hardcourts. (AP)

"If I'm playing like this, I'm not going to beat Rafa," Federer said. (AP)

This was the first year since 2002 that Federer has not made a Grand Slam final. (AP)

Instead, it will be Tommy Robredo in his first US Open quarter-final against second-seeded countryman Nadal, who dispatched Germany's 22nd-seeded Philipp Kohlschreiber 6-7 (4/7), 6-4, 6-3, 6-1. (AP)

"To beat Roger, it's something amazing," Robredo said.
"It's like a dream. I am so happy. It was a great day." (AP)

Federer, 32, won only two of 16 break-point chances.
"I'm delighted. Today the difference is I won the break points and he did not," said Robredo. (AP)

Federer, whose seventh seeding at the US Open was his lowest at a Grand Slam event since 2002, hit 45 winners but also made 43 unforced errors and managed only five aces. (AP)

"I started badly," Federer said. "But I struggled throughout, which is not very satisfying. I missed so many opportunities. Rhythm was off. When those things happen, clearly it's always going to be difficult." (AP)
