Sawt Falasteen - Osaka crushes Gauff at US Open as Sinner, Swiatek roll into quarters

The Japanese star powered past third seed Gauff 6-3, 6-2 in a highly-anticipated but lopsided fourth-round showdown of former US Open champions on the Labor Day holiday in New York.

Osaka broke in the very first game in front of an expectant Arthur Ashe Stadium crowd and was untouchable on serve in a ruthless display against a misfiring Gauff, who hit 33 unforced errors.

"This is my favourite court in the world and it means so much to me to be back today," said Osaka, who looks primed for a tilt at a fifth Grand Slam.

"This is kind of uncharted territory at this point of my career," added Osaka. "I'm just enjoying it. I'm having fun."

The 27-year-old, a two-time US Open champion, is enjoying her deepest run at a major since winning her second Australian Open title in 2021.

It has been a painstaking climb back towards the top of the game for Osaka, who returned to tennis last year following the birth of her daughter in 2023.

"I was in the stands two months after I gave birth watching Coco and I just really wanted an opportunity to come out here and play," said Osaka, who also beat a 15-year-old Gauff at the US Open in their first meeting in 2019.

Gauff conceded the mental toll of a challenging first week and the efforts to remodel her faltering serve had weighed heavily on her.

"I think emotionally how much this week was, I think today I just stepped in, and I maybe was a little bit empty," she said.

Osaka plays Czech 11th seed Karolina Muchova in Wednesday's quarter-finals. Muchova beat Ukrainian 27th seed Marta Kostyuk 6-3, 6-7 (0/7), 6-3 and is seeking a third straight semi-final at Flushing Meadows.

Reigning men's champion Sinner obliterated the unpredictable Alexander Bublik 6-1, 6-1, 6-1 in just 81 minutes to start the night session.

Bublik, the only player to beat Sinner this season aside from Carlos Alcaraz, had not dropped serve all tournament but was broken eight times by the world number one.

"He had a very tough match the last match, today he didn't serve as well as he usually serves, and I broke him early," said Sinner. "Overall, I'm very happy."

Bublik smiled as he embraced Sinner at the net after the defeat, and could be heard telling the Italian: "You're so good, this is insane."

Sinner is trying to become the first man to defend the US Open since Roger Federer won the last of his five successive titles in 2008.

He advances to an all-Italian match-up with 10th seed Lorenzo Musetti, who demolished unseeded Spaniard Jaume Munar 6-3, 6-0, 6-1 to reach his first US Open quarter-final.

- Swiatek 'in the zone' -

Swiatek brushed off Russian 13th seed Ekaterina Alexandrova 6-3, 6-1 in barely an hour to extend her Grand Slam winning streak to 11 matches as she targets a second US Open crown.

"I felt like in the beginning she played fast but later on I felt in my bubble, in the zone," said Swiatek.

The Polish second seed faces Amanda Anisimova in a repeat of the Wimbledon final, which Swiatek won 6-0, 6-0. The American thumped Brazilian 18th seed Beatriz Haddad 6-0, 6-3.

Men's eighth seed Alex de Minaur sealed his passage to the quarter-finals with a 6-3, 6-2, 6-1 win over Swiss qualifier Leandro Riedi.

De Minaur put the world number 435 to the sword with eight breaks as he swept into a sixth Grand Slam quarter-final. He has never made it past the last eight though.

The Australian next meets Canada's Felix Auger-Aliassime, who defeated Andrey Rublev 7-5, 6-3, 6-4 to reach his first Grand Slam quarter-final in three years.

Auger-Aliassime's best run at a Grand Slam came when he advanced to the semi-finals of the US Open in 2021.

"It feels even better than the first time," Auger-Aliassime, 25, said of returning to the last eight in New York.

"I think the first time at 21 I was kind of on my way up. To have a few setbacks, injuries, struggles with confidence... to come back for a second time to the quarter-finals here, it feels much better."
