NEW YORK — Novak Djokovic put aside all of it, from his opponent’s unheard-of, middle-of-a-set chance to change out of sweat-soaked clothes and shoes, to consecutive time violations because he let the serve clock expire, to the 16 break points he wasted.

All that mattered, really, was that Djokovic managed to do what Roger Federer could not two nights earlier: 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 to get to the tournament’s semifinals for an 11th appearance in a row. He sat out last year because of an injured right elbow.

The No. 6-seeded Djokovic, who won Wimbledon in July, had been drawn to face Federer in the quarterfinals. 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.

“I was, alongside many other people, anticipating the match against Federer,” said Djokovic, who faces 2014 U.S. Open runner-up Kei Nishikori in the semifinals.

Earlier Wednesday, Nishikori defeated the man he lost to in the final four years ago, Marin Cilic, 2-6, 6-4, 7-6 (5), 4-6, 6-4. Add that to No. 20 Naomi Osaka’s 6-1, 6-1 win over unseeded Lesia Tsurenko of Ukraine, and Osaka and Nishikori give Japan semifinalists in both men’s and women’s singles at the same Grand Slam tournament for the first time in tennis history.

“It’s great to see,” said Nishikori, who is into his third major semifinal — all in New York — but is still in search of his initial Slam trophy.

For Osaka, who is 20, this is her first trip past the fourth round at a major. She purported to be “freaking out inside,” even if it certainly never showed.

She’ll face No. 14 Madison Keys of the U.S. to

night. Serena Williams plays No. 19 Anastasija Sevastova of Latvia in the other semifinal.

Keys was one of four American women in the final four a year ago.
