Victoria Mboko will not defend her title at the Canadian Open 2026. The World No. 10 announced her withdrawal on Instagram Tuesday, citing a lingering left knee MCL injury.
Queen's Club Injury Continues to Sideline Mboko
Mboko sustained the injury last month at Queen's Club after slipping on the grass during a match against Karolina Pliskova. That fall ended her grass-court season, and her planned doubles run at the HSBC Championships with Serena Williams. Now, the setback will keep her out of the entire North American hard-court swing.
The National Bank Open, which runs August 2nd through August 13th, holds special meaning for the Toronto native.
"Knowing that I won't be able to play this year, it's very saddening," Mboko said. "But I feel like I have so many more years ahead of me to play this tournament."
Mboko's WTA Rankings Rise Halted
Her disappointment is understandable given her rapid climb in the WTA rankings.
Last summer in Montreal, the then-18-year-old entered as a wild-card ranked No. 85. She defeated four Grand Slam champions in Sofia Kenin, Coco Gauff, Elena Rybakina, and Naomi Osaka to capture her first career title. That run propelled her into the Top 10 by February, and she has since reached three singles finals in 2026.
Though MCL injury pauses her momentum, Mboko promised her hometown fans she will return stronger.
Serena Williams plans to extend her tennis comeback to the 2026 US Open, according to coach Rennae Stubbs.
The six-time US Open singles champion returned to competitive play at Wimbledon after nearly four years away but fell to Maya Joint in three sets. A right knee injury during that match then forced her to withdraw from her planned doubles run alongside sister Venus.
Still, Stubbs told reporters at Wimbledon that Williams's goals are clear. "Her intention is to keep playing; the US Open as well," Stubbs said.
But the timeline depends entirely on her body.
Williams's US Open Comeback Hinges on Recovery After Wimbledon
Williams recently shared images on Instagram of fluid drained from her knee after her injury at the All England Club, though she noted the swelling should not recur.
Unlike her Wimbledon prep where she played just two doubles matches beforehand, Williams wants more singles tune-ups this time. Hard-court warmup events in Toronto and Cincinnati could provide that match play.
"As long as physically she can go -- and I'm hoping in a few weeks that's the case -- to get her back on the court and hitting balls," Stubbs said.
Stubbs also believes the surface shift will help. Hard courts offer Williams better stability than grass, and she has long thrived on them. Main draw play at the US Open begins Aug. 30 will the full playing field revealed on Aug. 20.
Aryna Sabalenka won her first Grand Slam of the 2025 WTA season on Saturday, with the world No. 1 defeating then-No. 9 Amanda Anisimova 6-3, 7-6(3) to claim the US Open trophy — the final Slam of the year.
"To bring the fight and be able to handle my emotions the way I did in this final, it means a lot," Sabalenka said following the match. "I'm super proud right now of myself."
After successfully defending her 2024 US Open title — and claiming tennis's top 2025 paycheck in the process — Sabalenka is now the tournament's first repeat champion since 2014, when Serena Williams claimed a third straight trophy at the New York Slam.
The 27-year-old narrowly avoided a Slam-less year, going without a trophy despite reaching both the Australian Open and French Open finals as well as the Wimbledon semifinals.
"I think because of the finals earlier this season, this one felt different," Sabalenka said. "All of those lessons are making me tougher, tougher, and tougher."
As for Anisimova, the US rising star added a new career-high WTA ranking alongside her second straight Grand Slam final appearance on her 2025 resume, rising to world No. 4 in Monday's update.
Also earning a noticeable bump on Monday was Japanese star Naomi Osaka, who clocked in at No. 14 after a stellar Grand Slam comeback run to the 2025 US Open semifinals.
This year's US Open champions are cashing in, with the pro tennis season's final Grand Slam boosting its overall prize money by 20% — and upping the 2025 men's and women's singles winner's payout to a record $5 million each.
Total player compensation will rise to $90 million across all competitions, making the 2025 US Open the highest-paying tournament in tennis history, with its singles champions banking the biggest payday in the sport's history.
Finalists and semifinalists are also getting a bump, with this year's runners-up cashing $2.5 million checks while semifinalists will walk with $1.26 million each.
In addition, champions of the men's, women's, and mixed doubles competitions will each walk away with $1 million for the first time in US Open history.
In 2024, the New York City Slam's total purse weighed in at $75 million, with singles winners earning $3.6 million each — making this year's $5 million check a 39% raise.
Since then, 2024 US Open champ Aryna Sabalenka and others have spoken out about increasing both payments and transparency in pro tennis, with the sport's Top-20 ranked women and men reportedly co-signing a letter requesting "substantial" purse increases to all four Grand Slams this past April.
While both the French Open and Wimbledon increased this year's overall purses by 5% and 7%, respectively, the US Open "made a deliberate and concerted effort to ensure double-digit percentage increases from 2024 in all rounds of all events for all players," according to the tournament's press release.
Notably, the 2025 Australian Open increased its overall prize pool by over 11%, though that boost came before the players' letter and not all winning categories saw double-digit percentage raises.
Four-time Grand Slam winner Naomi Osaka has found her stride at the 2025 Canadian Open, with the 27-year-old fan favorite advancing to the Montréal tournament's quarterfinals as she prepares to chase a third US Open title later this month.
After parting ways with coach Patrick Mouratoglou just 10 days ago, world No. 49 Osaka will contend in her first WTA 1000 quarterfinal in three years on Tuesday, when she'll face off against Ukraine's No. 13 Elina Svitolina for a spot in the semifinals.
"I think I need to pace myself and go for the mini goals, and they'll eventually turn into the big goals," the Japanese star said after topping Latvia's No. 26 Jeļena Ostapenko in the third round on Friday.
Tuesday's other quarterfinal sees US star and 2025 Australian Open winner Madison Keys on the Canadian court, as the world No. 8 takes on No. 19 Clara Tauson after the Danish national upset reigning French Open champion No. 3 Iga Świątek in straight sets on Sunday.
Already punching their tickets to the semifinals are Kazakhstan's No. 12 Elena Rybakina and 18-year-old phenom No. 85 Victoria Mboko — the youngest home-grown semifinalist in Canadian Open history — who each advanced with straight-set victories on Monday.

Keys and Tauson will kick off Tuesday's quarterfinals action at 6 PM ET, with Osaka clashing with Svitolina shortly afterward.

With the US Open rapidly approaching — the WTA season's final Grand Slam — the tennis world's hardcourt titans are tuning up at the 2025 Canadian Open.
This year's tournament is in full swing up in Montréal, allowing players to hone their skills before next week's Cincinnati Open sets the tone for the annual New York City Slam.
Though stars like world No. 5 Mirra Andreeva, No. 9 Jasmine Paolini, and No. 11 Emma Navarro stumbled out of contention in the tournament's first two rounds, many heavy-hitters are still in play, including all three 2025 Grand Slam winners: Australian Open champion No. 8 Madison Keys, French Open victor No. 2 Coco Gauff, and newly crowned Wimbledon champ No. 3 Iga Świątek.
Joining Gauff in punching her ticket to Saturday's Round of 16 is fellow US player No. 32 McCartney Kessler, while Keys and several others in the US contingent — No. 4 Jessica Pegula, No. 7 Amanda Anisimova, and No. 116 Caty McNally — will battle to advance from the Round of 32 on Friday.
Other fan favorites are also still in the mix, including Japan's No. 49 Naomi Osaka and the UK's No. 33 Emma Raducanu, while 18-year-old phenom No. 85 Victoria Mboko is impressing as Canada's last-standing contender in play.
Notably sitting out this week is world No. 1 Aryna Sabalenka, with the 2024 US Open champ prioritizing her mental and physical rest ahead of her title defense.

For the second year in a row, there will be a US tennis player facing Aryna Sabalenka in the final of the US Open, after Jessica Pegula wrapped up the best week of her career.
Having reached the quarterfinals in all four major tournaments, Pegula finally broke through to her first Slam semifinal and then final this week with wins over Iga Swiatek and Karolina Muchova.
A career-best run
Currently ranked No. 6 in the world, Pegula has played some of the best tennis of her career recently, reaching the quarterfinal of the Australian Open in 2021-23, and the quarterfinal of the French Open in 2022, and the US Open in 2023.
But Wednesday's straight-set win over World No. 1 Swiatek proved to be her first time breaking 'the quarterfinal curse,' with the hope of carrying the momentum all the way to the final.
Pegula had to battle back from a slow first set in her semifinal on Thursday, as Muchova took an early 6-1 lead and then a 3-0 advantage in the second set.
"I came out flat, but she was playing unbelievable," Pegula said after the match. "She made me look like a beginner. I was about to burst into tears because it was embarrassing. She was destroying me." But the 30-year-old battled back to take the second set 6-4 and rolled to a 6-2 win in the deciding third set, continuing her impressive 15-1 record since the Paris Olympics.
"I was able to find a way, find some adrenaline, find my legs," Pegula said. "At the end of the second set into the third set, I started to play how I wanted to play. It took a while but I don't know how I turned that around honestly."
Finishing the job
Pegula will face World No. 2 Aryna Sabalenka, who defeated her in Cincinnati, and who advanced past Emma Navarro in straight sets on Thursday. Sabalenka has only dropped one set this US Open, after not participating in the Olympics. The Belarusian will be looking for her second-ever Grand Slam title after coming up just short against Coco Gauff in New York in 2023.
"Hopefully I can get some revenge out here," said Pegula.
In her first-ever Grand Slam quarterfinal victory, No. 6-seed Jessica Pegula knocked No. 1 Iga Świątek out of the 2024 US Open in straight sets Wednesday night.
Now in uncharted territory, the US tennis star will aim at extending her historic run in tonight's semifinal against unseeded Czech opponent, Karolina Muchová.
Quarterfinal victory proved Pegula's dominance
The 30-year-old Pegula, who has yet to drop a set all tournament, took control of yesterday's match immediately, winning the first game on Świątek's serve — the five-time Grand Slam winner's first broken serve in 26 games.
Świątek, the 2022 US Open champion, committed 18 unforced errors in the first set. Visibly frustrated with her performance, the Polish phenom retreated to the locker room to regroup — a move that ultimately proved unsuccessful in the wake of Pegula's relentless 6-2, 6-4 victory.
After six previous Grand Slam quarterfinal attempts, Pegula celebrated, telling the crowd post-match that "there have been so many freaking times, and I just kept losing.... So thank God I was able to do it. And finally — finally! — I can say, 'Semifinalist.'"
Two US contenders will feature in tonight's semis
Pegula isn't the only contender making her Grand Slam semifinal debut tonight. Before Pegula takes the court, fellow US player No. 13 Emma Navarro will take on reigning back-to-back Australian Open champion No. 2 Aryna Sabalenka.
Sabalenka, who fell to US star Coco Gauff in last year's US Open, hopes for better luck against Navarro — the player who ousted the No. 3 defending champ last weekend.
If both Pegula and Navarro emerge victorious, Saturday's US Open final would be the first contested by two US athletes since Sloane Stephens defeated Madison Keys for the 2017 title. It would also pit two New York locals against each other on their home Grand Slam court: Pegula hails from Buffalo, NY, while Navarro was born in NYC.
How to watch the 2024 US Open semifinals
Navarro and Sabalenka will kick off tonight's Grand Slam action at 7 PM ET, with Pegula's match against Muchová immediately following. Both semis will air on ESPN.
With the US Open's first round coming to a close, both surprise performances and expected wins headlined the season's final Grand Slam heading into today's second round.
Naomi Osaka pulls off stunning upset with US Open win
Looking decidedly dangerous, 2020 US Open champ Naomi Osaka — a wild card entry at 88th in the world — beat No. 10 Jeļena Ostapenko in straight sets on Tuesday.
After stepping away for mental health reasons and the birth of her daughter, yesterday marked Osaka’s first top-10 win in over four years.
"Last year, I was watching Coco play, and I so badly wanted to step on these courts again and I didn’t know if I could," an emotional Osaka told reporters after the victory. "Just to win this match and to be in this atmosphere means so much to me."
Other past US Open champions see mixed results
Joining Osaka in the second round are fellow US Open winners Iga Świątek (2022) and Coco Gauff (2023). No. 3 Gauff aced her first match 6-2, 6-0 on Monday, but No. 1 Świątek faced a tougher challenge from Russian Kamilla Rakhimova on Tuesday.
The Polish phenom made 41 unforced errors, coming dangerously close to a forced third set before a tiebreaker allowed Świątek to continue her hunt for a sixth Grand Slam title.
Other past US Open champs weren’t so lucky, with 2019's Bianca Andreescu and 2021's Emma Raducanu joining 2017's Sloane Stephens on the ousted list.
Retiring Danielle Collins exits final Grand Slam singles tournament
While most of the 32 seeded singles players survived round one, US star Danielle Collins's run ended on Tuesday. Coming off a solid fourth-round Wimbledon exit, the world No. 11 fell to No. 49 Caroline Dolehide 1-6, 7-5, 6-4, despite defeating the fellow US pro in five of their six previous meetings.
Collins, who announced her plan to retire after this season in January, suffered an abdominal injury at the Olympics that saw her miss the Toronto and Cincinnati US Open tune-ups.
Madison Keys was just 16 when she featured in her first US Open, and the home Grand Slam holds a special place in the now-29-year-old's tennis star's heart.
"It's truly the best, greatest feeling in the entire world," Keys told JWS last week. "I think there have been some of my most heartbreaking moments in front of a US Open crowd, but also some of my absolute most favorite, literally to the point of mid-match getting goosebumps."
Ahead of today's 2024 US Open kickoff, Keys commented on the power of the New York Slam's fans, saying, "The thing I've always loved about playing at the US Open is that, literally no matter how down and out you felt, the entire crowd was still there trying to get you through and push you through."
A chaotic 2024 sets up Keys's US Open appearance
The world No. 14 has had a rollercoaster 2024 season, missing the Australian Open due to injury before making solid finishes at WTA events in Miami, Madrid, and Strasbourg.
The Illinois product then suffered an injury at Wimbledon, withdrawing in the Round of 16 while in a winning position against eventual finalist Jasmine Paolini. "As devastating as that match against Jasmine was, it was also one of my favorite matches that I've played," she explained. "Just because I feel like we were both playing so well."
Her veteran perspective allowed Keys to calmly view the injury for what it was: a simple setback. "[Wimbledon] was really reassuring that I didn't do anything wrong," Keys said. "It wasn't this big thing that we had to worry about or manage. It was just really horrible timing."
"I've started to change my perspective on success and goals," she added. "At the end of every day, being able to say, 'Okay, did I accomplish my goal? If not, what were the lessons learned? How can I move forward with them?' I think that's honestly the best way to go about success in tennis."
Prioritizing health is vital to Keys's tennis career
The 2016 Rio Olympic semifinalist pulled out of the 2024 Paris Games in an effort to maintain her wellness and gear up for the season's final Slam — a decision she says was hard-won.
"It’s one of the greatest honors to be able to play for your country and play at an Olympics, and it was honestly one of my favorite tennis moments of my life," she said. "But I'm getting older — I've been on tour for a long time. They like to call me a veteran now, and I think you have to start shifting gears a little bit to prioritize the best schedule... to be able to maintain a high level and stay healthy."
At this stage in her career, Keys notes that every little thing matters, like putting nutrition and rest first in the run-up to another US Open while also partnering with supplement companies to boost her conditioning along the way.
"It's a lot about the details — we're constantly putting our bodies under insane amounts of stress and traveling," she said. "Being able to, like, literally not get a cold, something as small as that. I've been lucky to be able to partner with Thorne — that has been my absolute go-to — because if I can do all of the things right, I'm setting myself up for success.
"The other thing is prioritizing recovery, making sure that I have my whey protein, getting a good night's sleep, and being able to recover — those things are so important. Most people would think, 'Oh, it's about time in the gym and on the court.' That's obviously really important, but it's all of the little details that create the full picture."
Recognizing that pacing her seasons and listening to her body will help protect her health and, ultimately, her career, Keys is clear on her path forward. "At this point in my career, my biggest goal is I want to play tennis for as long as I want to play tennis," she said. "I don't want some outside force to be the reason that I have to step away from the game."
