Canada's Victoria Mboko stuns No. 1 seed Coco Gauff to reach NBO quarterfinals
It was billed as the tournament's marquee match. A rising Canadian star — and last remaining singles hope from the host country — facing her stiffest test yet against the No. 1 seed.
And she blew past her in just 62 minutes.
Mboko's stellar run at the National Bank Open hit a new level Saturday with a dominant 6-1, 6-4 victory over Coco Gauff of the United States, lifting the 18-year-old from Toronto into the quarterfinals before a raucous, sellout crowd at IGA Stadium.
'I don't even know what to say,' said Mboko, smiling in disbelief. 'I was shocked about it all. Everything came so fast. There were so many people. I feel like tonight I'll let it soak in a little bit more, but I'm still on the high a little bit.'
The whole year has been a high.
Mboko's ranking rocketed to 85th in the world this week after she began the year outside the top 300. That number is projected to jump into the 50s with her performance in Montreal, and her rise appears unlikely to end there.
After major crowd support for Eugenie Bouchard early in the tournament, the buzz in Montreal shifted around Mboko as the teenage sensation took centre court.
Mboko met the moment, flashing the powerful groundstrokes and blistering serve that few opponents have had answers for on the pro circuit this season.
"Your support was incredible," Mboko told the crowd in French after a chorus of "Olé, Olé, Olé!" chants echoed around the venue. "I'm really happy to win today."
'When I was up 5-4, the crowd started cheering even louder, and everything got super noisy,' she later added. 'I used that as more fuel for myself and to pump myself up a little bit more. I just used the crowd to my advantage as much as I could.'
Gauff, meanwhile, made unforced error after unforced error, firing some shots long and many more into the net.
Mboko, who will play Jéssica Bouzas Maneiro of Spain, saved all four breakpoint opportunities while converting four of her five chances.
She also won nearly 60 per cent of the points, her 11 unforced errors half of Gauff's 22 on a dismal night for the American star.
The youngster is only the second teenager — and first Canadian — to defeat Gauff, as well as the first player this season to not drop a single service game against her.
'I knew she would come in with a lot of confidence,' Gauff said. 'I knew that it would be tough. I don't know, I just felt like I could do better today, but I also knew that if I took my foot off the gas a little bit, that she would take advantage of those moments, and she did.
'She's playing high-level tennis. I think that's what showed today. I think she was the better player.'
The first set took a swift 25 minutes.
The 21-year-old Gauff double-faulted on the third point of the match, leading to an early break for the Canadian. In the seventh game, Gauff doubled-faulted and sent two shots into the net in succession to lose the set.
When the two players previously met at the Italian Open in May, Mboko also took the opening set but Gauff convincingly won the next two to snag the victory.
This time around, Mboko kept her foot on the gas.
'I was actually really thinking about it a lot during the match,' she said. 'I had flashbacks to when I played her in Rome a little bit. I just remember when she came out playing even better and stepped it up a bit better.
'Wanted to step my game up a little bit more and make sure I matched whatever she was producing, and I wanted to stay right there with her.'
Gauff, this year's French Open champion, scraped by with three-set wins in Rounds 2 and 3. She struggled with her serve, striking a whopping 37 double faults in the two matches combined — adding six more on Saturday.
Tied 3-3, she earned three breakpoint chances with the match tied 3-3, but committed an error each time as Mboko hung on to win the game.
Then with Mboko leading 5-4, Gauff doubled-faulted twice more to set up two match points for the Canadian, who quickly took advantage.
It's the latest chapter in a breakthrough season for Mboko, who also played in her first two Grand Slam main draws, reaching the French Open third round and Wimbledon second round.
Her impressive record in all competitions this season improved to 50-9, including 24-8 against players ranked above her.
In only her seventh WTA main draw, she advanced to the quarterfinals of a 1000-level tournament for the first time, knocking off higher-ranked opponents at each step.
Mboko opened with a win over 79th-ranked Kimberly Birrell, then upset 23rd seed and former Grand Slam champion Sofia Kenin before snapping Marie Bouzkova's seven-match winning streak with a relentless comeback and taking down Gauff, dropping one set the whole way.
'I do see someone who is going to have a really bright future,' Gauff said. 'She's very athletic. She's a great ball striker, and she seems pretty positive out there on the court, doesn't get really too negative.
'Hopefully we have many more battles, and I look forward to playing her again in the future."

Djokovic withdraws from ATP Cincinnati Masters
Novak Djokovic withdrew on Monday from this week's start of the ATP Cincinnati Masters, with the pullout coming a year to the day from his Paris Olympic gold medal victory. Tournament officials confirmed the news to The Athletic, meaning the 38-year-old Serb will have played no matches between his Wimbledon semi-final loss to Jannik Sinner and the US Open start in three weeks. World number one Sinner, who like Djokovic and Carlos Alcaraz skipped the current ATP Toronto Masters in order to rest and recover from Wimbledon, has been in Cincinnati since the weekend. Sinner and his team posted a golf course selfie to social media on Monday, one day after an opening practice session at the pre-US Open event. Djokovic, winner of 24 Grand Slam singles titles, first played Cincinnati in 2005 and won the last of his three titles there in 2023 after losing five previous finals. str/js

Rybakina advances to WTA Canadian Open semis
Elena Rybakina, the 2022 Wimbledon champion, advanced to the semi-finals of the WTA Canadian Open on Monday when Ukraine's Marta Kostyuk retired in the second set with a wrist injury. World number 12 Rybakina led 6-1, 2-1 when Kostyuk stopped the match, sending the Kazakhstan star into a semi-final against the winner of a later match between Spain's Jessica Bouzas Maneiro and Canadian teen Victoria Mboko. The top five seeds and seven of the top 10 seeds were ousted before the quarter-finals at Montreal, opening the door for such upstarts as 18-year-old Mboko, who eliminated top seed Coco Gauff. Rybakina, seeded ninth, seeks her third WTA title after Rome and Indian Wells in 2023. She has not reached a final since last year at Miami. Rybakina broke 24th-seeded Kostyuk to open the match and led 2-1 when Kostyuk received medical treatment on her right wrist and forearm. Kostyuk netted a backhand to surrender another break in the fifth game and Rybakina broke again to claim the first set in 37 minutes when Kostyuk sent a forehand long. In the second set, Rybakina held twice before Kostyuk retired after 54 minutes due to her wrist issues. js/jgc
