Federer Knocked Out In New York City

Roger Federer has been stunned in the U.S. Open's fourth round by 55th-ranked John Millman of Australia 3-6, 7-5, 7-6 (7), 7-6 (3).

It's the first time in Federer's career that he has lost to a man ranked outside the top 50 at Flushing Meadows.

The 20-time Grand Slam champion double-faulted 10 times, including twice in a row during the final tiebreaker.

Federer certainly had his chances to take control of the match, including two set points at 5-4, 40-15 in the second.

Millman will face Novak Djokovic in the quarterfinals.
