Daniil Medvedev rolled into the US Open fourth round and he was joined by Dominic Thiem on Saturday.
Russian third seed Medvedev – last year's runner-up – eased past J.J. Wolf in straight sets at Flushing Meadows in New York.
Thiem, who is seeded second for this year's grand slam, ousted 2014 US Open champion Marin Cilic.
As for exciting 15th seed Felix Auger-Aliassime, he completed Canadian history.
MEDVEDEV CRUISES INTO LAST 16
The Russian produced another dominant performance, beating Wolf 6-3 6-3 6-2 in one hour, 48 minutes.
Medvedev has not lost more than four games in a set through three matches, breaking seven times against his American opponent.
"It's good that I managed to win in three sets and I didn't even have to play [to] 7-5 because six months of not playing tennis, it's not easy to recover from playing five or four-set matches," Medvedev said. "With a day off and just a three-setter to play, I'm feeling good."
Next up for Medvedev is 2019 Australian Open quarter-finalist Frances Tiafoe, who reached the US Open fourth round for the first time after taking down Marton Fucsovics 6-2 6-3 6-2.
THIEM OUSTS CILIC
Cilic put up a fight but three-time slam finalist Thiem was too good in a 6-2 6-2 3-6 6-3 victory in the night session.
Thiem hit 38 winners as he moved through to the second week of the US Open for the fifth time in seven appearances.
"I'm not 100 per cent yet. I still have to raise my level if I want to go deeper," Thiem said after two hours, 27 minutes on court. "I'm normally capable of doing this in the Slams [and] hopefully here as well."
Thiem will meet Auger-Aliassime in the round of 16 after the Canadian sensation dispatched Corentin Moutet 6-1 6-0 6-4.
Two days after eliminating 2012 winner Andy Murray, Auger-Aliassime impressed again as he joined countrymen Denis Shapovalov and Vasek Pospisil in the fourth round – the first time three Canadian players have reached the second week.
The 20-year-old Auger-Aliassime also became the first player born in the 2000s to advance to a grand slam fourth round.
Last year's semi-finalist and sixth seed Matteo Berrettini, 10th seed Andrey Rublev and 21st seed Alex de Minaur also progressed.
