Federer stunned by 55th-ranked Millman in US Open 4th Round

NEW YORK -- Roger Federer served poorly. Closed poorly, too. And now he's gone, beaten at the US Open by an opponent ranked outside the top 50 for the first time in his career.

Looking slow and tired on a sweltering night in Arthur Ashe Stadium, the No 2-seeded Federer double-faulted 10 times, failed to convert a trio of set points and lost 3-6, 7-5, 7-6 (7), 7-6 (3) in the fourth round to John Millman in a match that began Monday and concluded at nearly 1 am on Tuesday.

It's only the second time in Federer's past 14 appearances at the US Open that he's lost before the quarterfinals. He is, after all, a five-time champion at the tournament, part of his men's-record haul of 20 Grand Slam titles.

"I have so much respect for Roger and everything he's done for the game. He's been a hero of mine, and today he was definitely not at his best," Millman said, "but, you know, I'll take it."
