No. 8 seed Alex De Minaur defeated qualifier Leandro Riedi 6-3, 6-2, 6-1 in the fourth round Monday to move into the quarterfinals of the US Open.
De Minaur advances to his sixth major quarterfinal, still seeking his first semifinal appearance at a Slam. To get over that hurdle he will have to get past 25th-seeded Felix Auger-Aliassime, who advanced by defeating Andrey Rublev 7-5, 6-3, 6-4 in a match in Arthur Ashe Stadium that took just over two hours.
Auger-Aliassime at age 25 is in the quarterfinals of a Grand Slam tournament for the fourth time, breaking a tie with Denis Shapovalov for the second-most such appearances by a Canadian man after Milos Raonic (10).
“Felix is that type of player that everyone knows that his top level is incredibly high, and when he’s playing with confidence, he’s very tough to beat,” De Minaur said. “This week he’s obviously playing some incredible tennis, and he’s got a lot of weapons.
“He’s got a great serve. He’s got a great forehand. He looks to dictate whenever he can. In that matchup for me it’s all about trying to disrupt his rhythm, not give him the chance to bully me on the court.”
Auger-Aliassime won for just the second time in nine career matches against Rublev, the No. 15 seed who slammed his racket after losing a point in the second set.
“As I won the first set, I felt like I was in control of the match,” Auger-Aliassime said. “Good win considering our head-to-head, considering how good he is as a player.”
Auger-Aliassime hadn’t made a major quarterfinal since the 2022 Australian Open, where he blew a two-set lead to Daniil Medvedev.
De Minaur, meanwhile, is the first Australian man to make consecutive US Open quarterfinals since Lleyton Hewitt reached seven straight from 2000 to 2006.
Riedi, at No. 435 in the world, was the lowest-ranked man to make the round of 16 at any major since Richard Krajicek made the quarterfinals at Wimbledon in 2002 ranked No. 1,093.
Top-ranked Jannik Sinner faces Alexander Bublik in the Arthur Ashe Stadium night session. The winner of that match will take on 10th-seeded Italian Lorenzo Musetti, who routed Spain’s Jaume Munar 6-3, 6-0, 6-1 on Louis Armstrong.
