Djokovic Advances To U.S. Open Semi Finals

Novak Djokovic managed to do what Roger Federer could not: beat 55th-ranked John Millman at the U.S. Open.

Djokovic moved a step closer to a third championship at Flushing Meadows and 14th Grand Slam title overall by eliminating Millman 6-3, 6-4, 6-4 in the quarterfinals.

The No. 6-seeded Djokovic, who won Wimbledon in July, had been drawn to face Federer with a semifinal berth at stake.

But Millman scuttled that showdown by stunning the 20-time Grand Slam champ in four sets in the fourth round on a hot and humid evening that Federer said sapped his energy and made it hard to breathe.

Djokovic now will face Kei Nishikori in the semifinals.
