 Casper Ruud (NOR) vs.  Matteo Berrettini (IT)
Fifth seed Ruud is exploring new territory in New York, in more ways than one.
The Norwegian has made it to the quarter-finals of the US Open for the first time with a string of battles over the past two weeks, while the fifth seed also knows that Tuesday’s win against thirteenth seed Berrettini will put him two places to No. 2 at the Pepperstone. lift. ATP Live Ranking.
The 23-year-old could become the new world No. 1 if he makes it to the championship game at Flushing Meadows, but he is wary of Berrettini’s threat. Ruud defeated the Italian in three sets in three sets at Gstaad in July to win his ninth tour-level title and believes his ability to counter Berrettini’s massive serve will be key to his chances of a repeat success in Tuesday’s quarterfinals.
“When we played in Gstaad, the conditions were very fast, even though it was on clay, and it bounced a lot,” said Ruud, who leads Berrettini 3-2 in the pair’s ATP Head2Head series. “So I mostly stayed inside and tried this strategy, which didn’t work the whole game, but in the end I was able to win some key moments on it.
“Let’s see. You have to guess right sometimes, of course, and see if you can try to read where he’s going.”

Ruud’s previous best show in New York, a third-round performance in 2020, was ended in straight sets by Berrettini. The Italian showed on Sunday that he can also make it difficult if necessary in his fourth round victory against Alejandro Davidovich Fokina, when he triumphed in five sets after three hours and 45 minutes.
That win improved the 2019 US Open semi-finalist’s record to 16-4, and he spoke afterwards about the importance of staying at the forefront against Ruud if he wants to avenge the loss in Gstaad.
“I think the key is to be aggressive with him,” Berrettini said. “I’m going to try to make him run and not run too much. I think the key is to be aggressive, use my weapons, my serve, of course my forehand.”
The match is also important for both players’ hopes of qualifying for November’s Nitto ATP Finals. Ruud is currently fourth in the Pepperstone ATP Live Race To Turin, while Berrettini is 13th.
 Nick Kyrgios (AUS) vs.  Karen Khachanov
Kyrgios and Khachanov’s only previous Grand Slam encounter was a memorable one. The Australian took four hours and 26 minutes to beat Khachanov in a remarkable 6-2, 7-6(5), 6-7(6), 6-7(7), 7-6(8) victory over the Australian of 2020 Open.
Despite producing what he later described as “probably the most blunt game of all time” against Daniil Medvedev in the fourth round in New York on Sunday, Kyrgios delivered a further scintillating performance at Arthur Ashe Stadium to beat the world No. 1 and set a record. second meeting in the majors with 27th seed Khachanov.
Kyrgios has found his best level in the Tour in recent months, with 19-3 on the North American hard courts after his run to a first Grand Slam final at Wimbledon in July. The Australian says he is fueling his strong streak of results as he chases his first major title in New York.
“Of course winning helps. I have won a lot this year,” Kyrgios said after his victory in Medvedev. “The motivation was there. It is easy to train. It is of course easier to wake up when things are going well. I was just tired of disappointing people. I don’t know, I just feel that way. I feel like I’m making people proud now.”
Like Kyrgios, world number 31 Khachanov has made it to the quarterfinals in New York for the first time. The 26-year-old outlasted Pablo Carreno Busta in an epic fourth round on Sunday and is hopeful that he made a turn at Flushing Meadows, where he held a 5-6 tournament record for this year’s tournament.
“To be honest, I had a really great match against Rafa in 2018 (a clash in the third round of 2018) and good memories,” said Khachanov. “But after that, the performance in New York wasn’t that good, so I was a little nervous this year because I wanted to do well, and I feel like I’m playing good tennis.”
