Andrei Rublev (6) vs Grigor Dimitrov (9)

There are 16 players left in the men’s field. Only two have won a Grand Slam title. They are both on the same side of the draw and will meet in the quarterfinals, if they get there.

For the remaining 14, Jannik Sinner and Daniil Medvedev are in thin air, but only one of them will get a taste of it at 2 p.m. at Arthur Ashe Stadium next Sunday. Andrey Rublev, who has been struggling with racket scars on his knees and thighs for the past few months, has never made it past a quarterfinal; Grigor Dimitrov, who has revived in the same period, has three semifinals to his name.

With the US Open set to be a major tournament with high potential, both men are ready to take their chance.

Emma Navarro (13) vs Coco Gauff (3)

Flashback to a week ago, two months ago. It’s dark in southwest London and Coco Gauff is screaming in the spotlight at Wimbledon. “Tell me something,” she says to Brad Gilbert, her coach. On the other side of the net is Emma Navarro, on her way to a straight-sets victory.

These two knew each other in junior classes, before Cori Gauff was “Coco” and a world-famous athlete, and before Navarro was on a seemingly inexorable rise into the top 10. Gauff knows what’s coming — off-speed forehands, surprising changes of pace. Now she has to deal with it.

Frances Tiafoe (20) vs Alexei Popyrin (28)

Friday’s heroes meet at Arthur Ashe. Tiafoe, who took back what Ben Shelton took from him 12 months ago, in five sets. Popyrin, who beat Novak Djokovic for the third time this year at a Grand Slam and recorded a first victory against him. Tiafoe will have the sound and fury on his side; Popyrin the prestige of beating a reigning champion. Shelton said Tiafoe returned his serve better than anyone else all year after his loss; Tiafoe will have to do the same again against the Australian.

Zheng Qinwen (7) vs Donna Vekic (24)

A repeat of last month’s Olympic gold medal match, in which Zheng, one of the WTA Tour’s shrewdest tacticians, used high, heavy spin — and the occasional outright moonball — to neutralize Vekic. That’s not easy on a court faster than the clay of Paris, and the Croatian should have more opportunities to slam her inside-out forehand into the corners.

Paula Badosa (26) vs Wang Yafan

Paula Badosa and Stefanos Tsitsipas are going through a period of contrasts as a couple. The Greek’s career is, by any measure, in decline. Badosa’s career is on the mend, having returned from an injury she thought might end it. Tsitsipas loves New York, but they are not on the same page. Badosa is not much of a fan, and she is in the last 16. Wang Yafan is her first Grand Slam opponent in the fourth round, having defeated former finalist Victoria Azarenka in the previous round.

Casper Ruud (8) vs Taylor Fritz (12)

Is there a three-time Grand Slam finalist calmer than Casper Ruud? Down two sets against Shang Juncheng on Friday, it looked like he was going to explode from a promising position, which has happened a few times lately. Instead, he won the next three sets 18 games to four. Taylor Fritz, meanwhile, has quietly gone through the draw, just like he did at Wimbledon. Expect a few tiebreaks.

Brandon Nakashima vs Alexander Zverev (4)

Of all the players remaining in the men’s draw, Alexander Zverev will probably see this US Open as a chance. That might not be such a good thing. Zverev, who led Dominic Thiem by two sets in the 2020 final before losing two on merit and one on nerves, lost the French Open final to Carlos Alcaraz earlier this year. At that tournament, he said he felt he had a chance to win; he said the same at Wimbledon, where a knee injury hampered his loss to Fritz. Nakashima, whose serve is currently one of the best on the ATP Tour, took down one of the best returners, Lorenzo Musetti, in the previous round. Expect more tiebreaks in this one.

Elise Mertens (33) against Aryna Sabalenka (2)

Aryna Sabalenka last lost to Elise Mertens in 2018, and in their last meeting in New York, the Belgian won just five games. The complicating factor here? Recovery. Sabalenka didn’t take the court until the early hours of Friday morning before being taken out in three sets by Ekaterina Alexandrova. She said she got home at 3am and slept until noon. Mertens had finished with Madison Keys a few hours before the Belarusian even got going.
