Carlos Alcaraz surged into the quarter-finals of the US Open on Monday as upsets dominated the women's draw with Ons Jabeur and Jessica Pegula becoming the latest highly ranked players to go crashing out.
Defending champion Alcaraz, who has only dropped one set on his journey into the last eight, produced a dominant display to overwhelm Italian world No.61 Matteo Arnaldi, winning 6-3, 6-3, 6-4 in 1hr 57min.
The 20-year-old Alcaraz is bidding to become the first man since Roger Federer in 2008 to successfully defend the US Open after winning the title for the first time last year.
The identity of the Spaniard's quarter-final opponent will be confirmed later Monday, with Alcaraz due to face either Germany's Alexander Zverev or Italy's sixth seed Jannik Sinner in the last eight on Wednesday.
A match with Sinner would be a repeat of last year's quarter-final classic between the two men, which set a record as the latest ever finish for a US Open game after wrapping up at 2.50am.
"I think the intensity from the beginning until the last ball, I played a really solid match, less mistakes," Alcaraz said after Monday's brisk victory.
"I'm really happy with the performance in general."
In other men's matches on Monday, eighth-seeded Russian Andrey Rublev advanced with a 6-3, 3-6, 6-3, 6-4 defeat of Britain's Jack Draper.
Rublev will now face an all-Russian quarter-final against close friend Daniil Medvedev, the third-seeded 2021 US Open champion who punched his ticket to the last eight with a 2-6, 6-4, 6-1, 6-2 defeat of Australian 13th seed Alex de Minaur.
Rublev, who has known Medvedev since childhood, is godfather to his quarter-final opponent's daughter.
- Pegula sunk by friendly fire -
In the women's draw meanwhile, more seeds bit the dust a day after world number one and defending champion Iga Swiatek was sent packing in the fourth round.
American third seed Jessica Pegula was routed in straight sets by compatriot and friend Madison Keys, while Tunisia's fifth seed Jabeur -- beaten in last year's final -- was ousted 6-2, 6-4 by China's Zheng Qinwen.
Pegula's campaign came to an abrupt halt in front of a packed Arthur Ashe Stadium as 2017 US Open finalist Keys recorded a dominant 6-1, 6-3 win in just 61 minutes.
Pegula was left with no answer as Keys unleashed a stream of 21 winners to her six.
Keys also punished her friend's shaky serve, breaking her five times on her way to wrapping up a comfortable victory.
"It's always tough having to play a friend but we've been doing it our whole lives at this point," Keys, 28, said.
The 17th-seeded Keys will now face Wimbledon champion Marketa Vondrousova of the Czech Republic in the quarter-finals on Wednesday.
Ninth seed Vondrousova booked her place in the last eight with a battling win over unseeded American Peyton Stearns, coming from a set down to win 6-7 (3/7), 6-3, 6-2.
Jabeur meanwhile, who has been struggling with flu since arriving in New York, finally saw her luck run out after scrapping her way to three-set victories in her previous two games.
The Tunisian simply had no answer to 23rd seed Zheng's blend of power and precision, with the 20-year-old from Shiyan looking far sharper than her weary opponent.
"Right now I feel just super happy and excited to play in a big stadium. I had a really good performance today," said Zheng.
Zheng is China's first US Open quarter-finalist since Wang Qiang in 2019. Two-time major champion Li Na reached the semi-finals in New York in 2013 and Peng Shuai did the same a year later.
Zheng's quarter-final assignment is a daunting date with second seed Aryna Sabalenka, who celebrated her rise to the pinnacle of women's tennis by routing Russia's Daria Kasatkina 6-1, 6-3 to secure her last eight berth.
Swiatek's exit on Sunday guarantees that the 25-year-old Belarusian will become the new world number one when the latest global rankings are released next week.
"It means a lot to me," Sabalenka said of her No.1 ranking after defeating Kasatkina.
"I've been pushing myself all this year to reach this goal. It's unbelievable, it's something crazy, I still can't believe it."
