Naomi Osaka produced her biggest victory in over four years as she knocked out third seed and home favorite Coco Gauff 6-3, 6-2 at the US Open last 16. In just 64 minutes, the former world No. 1 secured her first Grand Slam quarterfinal since the 2021 Australian Open and her first since becoming a mother in 2023. The win also marked her fifth career major quarterfinal, keeping alive a streak that has historically led to trophies.

Osaka celebrated quietly after match point, but her embrace with Gauff at the net spoke volumes. Then, during her on-court interview, the four-time Grand Slam champion praised her opponent. “I look up to her. The way she conducts herself is really special. To be such an amazing role model at such a young age, it’s a gift. I have all the respect in the world for her,” Osaka said.

Incredible.

Naomi reaches her first Grand Slam QF in 1658 days.

That’s 4 & a half years.

It’s also her first one as a mom.

✅3rd US Open QF
✅5th Slam QF

There are no words to describe how much she’s grown as a player.

Gauff’s Struggles, Osaka’s Composure

While Osaka’s clean hitting set the tone, Gauff’s unraveling proved costly. The 2023 US Open champion committed 33 unforced errors to Osaka’s 12 and struggled with her serve despite turning to biomechanics expert Gavin MacMillan earlier in the summer. A double fault on set point in the opener summed up her afternoon, and though she had her moments, the American never found her rhythm.

Osaka, meanwhile, was measured and purposeful. She broke Gauff multiple times, kept rallies compact, and showed flashes of her peak game that once made her the sport’s most formidable hard-court player. Even five double faults could not derail her, such was her command of the match. For Gauff, the defeat is a reality check in a season that began with promise after her Roland Garros win but has since fizzled to a modest 7-5 record post-Paris.

A Semifinal Dream Within Reach

For Osaka, the victory was both personal and symbolic. “I was in the stands two months after I gave birth to my daughter, watching Coco [in 2023]. I just really wanted an opportunity to come out here and play. This is my favorite court in the world, and this means so much to me to be back here,” she reflected.

Osaka will next face Czech Karolina Muchova in the quarterfinals, with a potential semifinal clash against world No. 2 Iga Swiatek looming. For now, though, this triumph already feels like the most meaningful step of her comeback journey.

I’m an academic turned sports writer from Raipur, India, specializing in the NFL, MMA, and tennis at The Playoffs. I previously wrote for Sportskeeda and hold a B.A. and M.A. in History. My journey into sports media began far from the field, rooted in the arts and sciences. Funny enough, I didn’t grow up a sports fan; I used to see it all as just noise. But a fateful writing job introduced me to the world of sports, and what began as a gig quickly became a passion. I understood those voices aren’t noise; they’re emotions of true sports fans, and now I am one of them, writing with the same energy I once questioned.
