Carlos Alcaraz, widely-regarded as Rafael Nadal’s Grand Slam heir apparent, claimed a season-leading 47th win of the year at the US Open despite breaking one of his shoes.
The 19-year-old third seed defeated Jenson Brooksby of the United States 6-3, 6-3, 6-3 on the back of 46 winners.
Alcaraz, a quarter-finalist in 2021, managed to break one of his tennis shoes as he slid to reach a ball mid-match.
“It’s the third time that I have done this. As you can see, I do a lot of sliding,” he said.
Meanwhile, Nick Kyrgios and Thanasi Kokkinakis enjoyed a straight-sets win (6-4, 7-6 [7-3]) over Andre Goransson and Yoshi Nishioka to reach the third round of the US Open doubles.
Speical K now faces Harri Heliovaara and Lloyd Glasspool in the next round.
British seventh seed Cameron Norrie made the fourth round for the first time with a comfortable 7-5, 6-4, 6-1 win over Danish teenager Holger Rune.
The match saw Rune lose his cool, accusing Norrie of repeatedly taking too long to serve.
“Are you kidding me?” the 19-year-old shouted at the umpire. “Just before the time runs out, he serves, every time.”
Rune suggested that Norrie was intentionally running down the serve clock by catching his ball toss.
“He does it every time and then I have to stop. Every time,” he said.
Norrie later said he wasn’t doing it on purpose, while Rune was less accusatory after the match.
“I have played him before and he has done the same every match. Maybe it is a sign of a tight game and he is nervous,” he said.
In the women’s draw, 21st seed Petra Kvitova downed ninth-seeded Garbine Muguruza after saving two match points.
Kvitova came through 5-7, 6-3, 7-6 (12/10) and will take on Jessica Pegula of the United States for a quarter-final place.
Two-time Wimbledon champion Kvitova said she had drawn inspiration from Serena Williams when the American legend saved five match points before eventually being eliminated in her third round tie.
“I watched Serena and it was amazing how she was saving match points, so I tried to do the same today,” said two-time US Open quarter-finalist Kvitova.
Muguruza’s defeat, her sixth in seven meetings against the Czech, left only four of the top 10 women’s seeds in the tournament.
One of those is eighth-seeded Pegula who ended the run of Chinese qualifier Yuan Yue, 6-2, 6-7 (6/8), 6-0.
Meanwhile, Rafael Nadal takes centre stage at the US Open on Saturday when the four-time champion looks to stretch his perfect record against Richard Gasquet to 18 wins.
The 36-year-old is the star attraction on Arthur Ashe Stadium which on Saturday (AEST) bid an emotional farewell to Serena Williams, who ended her career on 23 majors, one more than the 22 that Nadal currently possesses.
World number three Nadal and Gasquet were born just 15 days apart but their careers have enjoyed different trajectories.
As well as losing 17 times in 17 meetings with Nadal on the professional circuit, the Frenchman has dropped the last 31 sets against his childhood rival.
“We are both 36 years old, but in terms of recovery, we are not equal,” said Gasquet.
Nadal arrived at the US Open having played just one match since forfeiting his Wimbledon semi-final due to an abdominal injury.
In New York, he has dropped the opening set in both of his first two matches. Against Fabio Fognini, he even injured himself with his own racquet which bounced off the court and crashed into his nose.
Nadal also has concerns over his wife Mery Perello — due to give birth to the couple’s first child in the coming weeks.
Spanish media reports claimed she had been admitted to hospital as a precautionary measure.
“My wife is fine, but in the end these are situations that are sometimes more difficult to manage when you are away from home,” said Nadal.
