The 2026 Cincinnati Open matchups shifted Wednesday, as Japanese tennis favorite Naomi Osaka pulled out of the WTA 1000 event's main draw, citing fatigue after her Canadian Open run.
Her withdrawal thins one of the tournament's marquee quarters, where world No. 1 Aryna Sabalenka had been on a potential final-eight collision course with Osaka.
With Naomi Osaka Out, Coco Gauff & Aryna Sabalenka Top Cincinnati Draw
Sabalenka still anchors a section featuring No. 8 seed Elina Svitolina and 2019 champion Madison Keys. One quarter over, Coco Gauff heads a group that includes recent French Open winner Mirra Andreeva.
With Osaka out, attention swings to Gauff, who could face No. 10 seed Marta Kostyuk in a projected quarterfinal. The two last met in Doha in February 2025, and Gauff holds a 3-2 head-to-head edge. Sabalenka's path, meanwhile, opens up in Osaka's absence.
Still, fans can expect plenty of first-round drama at this year's tournament. A Yulia Putintseva vs Liudmila Samsonova match stands out, since the winner will face Gauff, and Putintseva stunned Gauff at the 2024 Cincinnati Open. Elsewhere, Czech veterans Sara Bejlek and 2016 champion Karolina Pliskova are set to collide.
Main-draw play begins Thursday, August 13th on Tennis Channel.
Naomi Osaka pushed Elena Rybakina to a deciding set at the 2026 Canadian Open on Tuesday, only to see the world No. 2 close out a 4-6, 7-6(5), 6-4 quarterfinal win in 2 hours, 33 minutes at the Toronto WTA event.
Elena Rybakina Launches WTA Toronto Comeback Against Naomi Osaka
Osaka broke in the opening game in Toronto, and she rode that lead through the first set in 42 minutes. Rybakina steadied in the second to dominate the tiebreak. In the decider, she broke for 4-3 and sealed the match with a second-serve ace, winning all 18 of her first-serve points in the final set.
"Super happy. It was a very difficult match," Rybakina said after the win. "I'm glad I could turn it around, I don't yet know how, but I think my serve helped me a little bit."
Coco Gauff now awaits her in the semifinal after Belinda Bencic withdrew from their match with a hip injury. A title run would pull Rybakina within four points of No. 1 Aryna Sabalenka. On the other side of the draw, Iga Świątek meets Elina Svitolina.
Osaka, now ranked No. 13, has not lifted a trophy since the 2021 Australian Open. She'll hope to break that streak at the upcoming US Open.
Tennis fan favorite Naomi Osaka bounced Leylah Fernandez from the National Bank Open on Sunday, taking the Round of 16 match 6-4, 6-4.
The result ended Canada's final singles contender at the 2026 Canadian Open. It also pushed Osaka into her third straight deep hard-court showing. The win is just more proof that Osaka's tennis has clicked since a Wimbledon quarterfinal in July, which included a stunning upset of world No. 1 Aryna Sabalenka, and a semifinal DC Open run earlier this month.
Naomi Osaka's Serve Decides the Match in Toronto
This weekend, it was her serve that carried the afternoon. The decisive break came at 3-3 in both sets, as Osaka fired six aces to Fernandez's one. She won 73% of her service points and dropped serve just once in a match that lasted 1 hour and 21 minutes.
Fernandez took the result hard. "I'm pretty disappointed. I had opportunities to put pressure on her, but I didn't do a good job of keeping the ball in," the 23-year-old told reporters.
Meanwhile, the road to another title is now wide open for Osaka.
Ranked No. 13, she's reached her first WTA 1000 quarterfinal since Montréal in 2025. She now faces a tough test in No. 2 seed Elena Rybakina, as Toronto prepares for the pair's first career meeting.
Naomi Osaka is into the quarterfinals in Washington for the first time. The four-time Grand Slam champion advanced at the 2026 DC Open 6-3, 3-1 on Wednesday, after opponent Ashlyn Krueger retired with a right ankle injury sustained in the opening set.
Krueger had called for medical attention while trailing in the first frame. She returned to the court but could not move freely, forcing the 53-minute contest to end before the second set reached its midpoint.

Before Krueger's retirement, though, Osaka controlled play from the baseline. She won 80% of points on her first serve and 77% off Krueger's second serve. Her winners outpaced her unforced errors 11-5, and she never faced a break point.
The run builds on a stretch that included a final in Bad Homburg and a quarterfinal at Wimbledon. Osaka credited her successful grass-court swing for easing her transition to the hard court this year.
"I think in that first practice back on a hard court, I finally realized why people said my game could suit a grass court because everything is a lot faster," she said.
On Friday, Osaka meets Elisabetta Cocciaretto, after the Italian knocked off No. 8 seed Emma Navarro in three sets earlier in the day.

Naomi Osaka Eyes Top 10 Ranking After Deep Wimbledon Run
Naomi Osaka, meanwhile, rose one place to No. 13 on the heels of her first career Wimbledon quarterfinal.
Along the way, the four-time Grand Slam champion knocked off reigning world No. 1 Aryna Sabalenka in the fourth round. That victory marked her third career win over a top-ranked player. At 28, she continues to narrow the gap on the top 10.
The movement extended further down the list, too.
Wimbledon champion Linda Nosková and finalist Karolína Muchová both reached new career highs inside the Top 10. The WTA rankings shakeup is setting up a competitive hard-court season which launches with the National Bank Open in Toronto.
Naomi Osaka's Wimbledon 2026 run ended Tuesday at the hands of Karolina Muchova. The 10th seed defeated Osaka 7-6(4), 6-4 on Court 1 to reach her first Wimbledon semifinal. With the win, Muchova became just the eighth active player to reach the semifinals at all four Grand Slams.
Muchova's Net Play Dictated Quarterfinal Win Against Osaka
The quarterfinal started with early fireworks as both players traded breaks. Muchova's net play and serving precision gradually took control, though, and after a tight first set reached 6-6, she ran away with the tiebreak 7-4. It was the first set Osaka had dropped all tournament.
From there, the second set stayed on serve until the ninth game. At 4-4, Osaka's unforced errors - she finished with 32 - handed Muchova a decisive break. Muchova sealed it with back-to-back aces, serving out the match to love.
Osaka's Grand Slam Quarterfinal Streak Ends at Wimbledon 2026
Osaka, the 14th seed, entered with a perfect 5-0 record in Grand Slam quarterfinals. Still, fatigue appeared to play a role. She cited the toll of consecutive weeks on tour without a day off as partly to blame for her lapse in form.
"I’m just getting old," Osaka joked after the loss. "It’s hard because I played so well in my last match, then today I just feel like I didn’t play well at all and I didn’t have any energy. I could feel it coming because I’ve played way more matches than I usually do before a Slam."
Despite the loss, Osaka's quarterfinal finish marks her deepest Wimbledon result.
Muchova now faces Coco Gauff in Thursday's Wimbledon semifinal.
Four-time Grand Slam champion Naomi Osaka earned a signature win at Wimbledon 2026 on Sunday. The 28-year-old handed World No. 1 Aryna Sabalenka her first straight set defeat at a major tournament since 2020.
The Round of 16 win propelled Osaka to her first Wimbledon quarterfinal round. It also marked her best Grand Slam run off hardcourt and her first win over a World No. 1 since 2019.
“It’s been a long time since I’ve had so much fun on the court,” Osaka said after the match. “And to do it here, it really means a lot.”
Wimbledon 2026 Women's Draw Shakes Up After Weekend Upsets
Wimbledon looks for a new women’s singles winner for the 10th straight season after this weekend’s action, with former winners Barbora Krejcikova, Elena Rybakina, and Iga Swiatek all suffering upsets. Swiatek's came at the hands of young phenom Alex Eala, who also made history with her win.

Osaka Flips the Script Against Sabalenka at Wimbledon
Up until this weekend, the Osaka vs. Sabalenka rivalry had tilted firmly in Sabalenka's favor. The world No. 1 had won all three of their 2026 meetings and held seven consecutive wins in their career head-to-head. But on a warm afternoon at Centre Court, Osaka set the tone early.
The four-time Grand Slam winner broke Sabalenka with an inside-out backhand winner to take a 2-1 lead, eventually running away with the opening set. Her flat groundstrokes and first-serve percentage gave her steady control. She finished with eight aces and 21 winners while saving both break points she faced.
The deciding second-set tiebreak was just as lopsided.
Osaka jumped to a 6-1 lead as Sabalenka committed an uncommon string of errors, allowing her opponent to cap the match at just one hour and 28 minutes.
"She overpowered me," Sabalenka said after the match. "I felt like it was incredible level from her."
Wimbledon 2026 Women's Quarterfinals Schedule
Before Sunday, Osaka had never beaten a top-10 player at a non-hard-court event. She is now the first Japanese woman to reach the Wimbledon quarterfinals since Ai Sugiyama in 2004.
With many of the top seeds eliminated, the Wimbledon women's quarterfinals schedule shifts again. Osaka next faces No. 10 seed Karolina Muchova on Tuesday, July 7, for a spot in the semifinals.
Naomi Osaka opened her 2026 Wimbledon campaign by making a statement before she even hit a ball.
The four-time Grand Slam champion walked onto Court 3 in a floor-length white kimono gown, threading Japanese tradition into the tournament's strict dress code.
Custom Naomi Osaka Wimbledon Dress Honors Japanese Heritage
Designed by Tokyo-based Hana Yagi and styled by Marty Harper, the robe featured crane and cherry blossom embroidery, an obi-style belt, and a tulle skirt up-cycled from vintage bridal garments. Beneath it, Osaka's custom Nike dress carried the theme, with 3D floral details and a scalloped hem inspired by kirigami, the Japanese art of paper cutting.
Osaka's 2026 Wimbledon dress honored Japanese heritage, but the world No. 14 also had cinema in mind.
"I love Kill Bill," she said. "I remembered absolutely falling in love with Lucy Liu's character. She has an all-white kimono, and I remember thinking that was really cool and amazing."
She hinted more looks are coming as she continue her Grand Slam run at the All England Club.
"I like to shake things up," Osaka said. "I try to mix it up every round."
On the London grass court, Osaka's game is matching her fashion. She beat France's Elsa Jacquemot 6-1, 7-5 in her Wimbledon opener, before dismissing Anastasia Gasanova 6-3, 6-2 to advance to the third round.
She next faces Australia's Daria Kasatkina on Friday, live on ESPN.
Naomi Osaka punched her ticket to the first grass-court final of her career on Friday. The four-time Grand Slam champion beat No. 52 Wang Xinyu in straight sets at the WTA 500 event in Bad Homburg, leaning on her serve and heavy baseline game to control the match from the opening games.
Osaka broke Wang's serve in the sixth game of the first set and held steady from there.
A brief serving lapse early in the second set threatened to shift the momentum. But the world No. 15 quickly settled back in, hitting eight aces and winning 79% of her first-serve points.
Osaka also converted four of her seven break-point chances, leaving Wang little room to compete. She eventually broke Wang three more times to close out the comfortable win.
Naomi Osaka Finds Her Footing on Grass at Bad Homburg
The result caps a sharp week on grass for Osaka, who has won every match in straight sets. After Thursday's quarterfinal, she credited coach Tomas Högstedt for helping her adapt to the surface.
"Obviously I can't say that I've had much experience on grass, but I feel really good right now," Osaka said after her win. "Tomas is helping me understand grass a lot more, so I feel pretty comfortable at this point."
Now, the 28-year-old turns her attention to Saturday's 2026 Bad Homburg Open final, marking her first shot at a WTA Tour title since the 2021 Australian Open. She awaits the winner of the other semifinal between No. 4 seed Karolina Muchova and qualifier Elena-Gabriela Ruse.
