Second seed Dominic Thiem moved into the quarter-finals of the US Open with a comfortable win over Canada’s 15th seed Felix Auger-Aliassime.
Auger-Aliassime, 20, beat Britain’s Andy Murray in round two but lost 7-6 (7-4) 6-1 6-1 against Thiem.
Third seed Daniil Medvedev only needed an hour and 38 minutes to defeat unseeded American Frances Tiafoe.
The Russian, last year’s beaten finalist at Flushing Meadows, went through 6-4 6-1 6-0.
He will face compatriot Andrey Rublev for a place in the last fourafter the 22-year-old came from a set down to beat Italy’s sixth seed Matteo Berrettini 4-6 6-3 6-3 6-3.
Thiem, third in the world, is the highest-ranked player left in the men’s singles after world number one Novak Djokovic was disqualified when he accidentally hit a tennis ball at a line judge during his match against Spain’s Pablo Carreno Busta on Sunday.
But the Austrian said he took nothing for granted against his Canadian rival.
“I was really nervous before as I knew I was going to play against an amazing opponent, an up-and-coming superstar,” said the 27-year-old.
“I started to have a great feeling in the second and third set.”
None of the players left in the men’s event have won a Grand Slam, although Thiem has lost in three finals – at the French Open in 2018 and 2019 and the Australian Open earlier this year.
Asked if Djokovic’s disqualification put him under more pressure, Thiem, who won the third set in only 26 minutes, told Amazon Prime Video: “It doesn’t. I really focus on myself and look match to match.
“For myself and the other players, it doesn’t matter if the big three [Djokovic, Roger Federer and Rafael Nadal] are still here or not, everyone just wants their hands on this trophy and it doesn’t matter who you have to beat.
“I’m probably one of the oldest players left, which is surreal.”
Thiem will face 21-year-old Australian Alex de Minaur after the 21st seed beat Canada’s Vasek Pospisil 7-6 (8-6) 6-3 6-2.
Medvedev, who was defeated by Rafael Nadal in last year’s final, was happy with the speedy nature of his win.
“I’m pleased with the fact I’ve won all of these sets and didn’t have to stay long on the court. That’s always good when you’re playing a Grand Slam,” said the 24-year-old.
“I was lucky enough to get the early break, relax a little bit and then I started playing amazing tennis after that.”
He and Rublev, 22, know each other well, having risen through the junior ranks together.
“Both of us were crazy on court, destroying racquets, complaining,” Rublev admitted.
“He has always been one of the biggest fighters that I have ever seen since he was, I don’t know, seven years old.
“He could play lobs for hours just to win. I remember we had a few battles when we were kids.”
