Victoria Mboko expected a tough fight from Coco Gauff. 

Before an electric home crowd, the Canadian teenager delivered a knockout. 

Eighteen-year-old Mboko repeatedly beat Gauff to the punch toppling the top-seeded American 6-1, 6-4 to score her biggest career win and roar into the Montreal quarterfinals. 

“It was one of the biggest matches I could have played so far in my career. So far I feel really happy with how it went,” Mboko told the media in Montreal. “Playing Coco is obviously never easy. She’s No. 2 in the world, and it’s been such a great opportunity for me to play against someone like her. I was just happy I kept my composure today and I pulled it through.”

A dynamic Mboko broke at 15 in the first and last games and spent much of the match playing off the front foot staying one step ahead of the two-time Grand Slam champion. 

“I mean, it is tough. I knew she would come in with a lot of confidence, and she’s won her
first couple of rounds easily,” Gauff said. “Honestly, I haven’t played the best this tournament, so 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.”

It was Mboko’s first career Top 10 win and she displayed both power and poise pulling it off.

Mboko, who swept former Australian Open champion Sofia Kenin in round two, made history as the third Canadian teenager to beat multiple Grand Slam champions at a single event. The explosive Mboko joins Bianca Andreescu (Auckland, Indian Wells and US Open in 2019) and Leylah Fernandez (2021 US Open) in achieving that impressive feat. 

When things got tight tonight at 4-all in the second set, Mboko did not crack and continued driving the ball deeper than the two-time Grand Slam champion in avenging a three-set loss to Gauff in Rome.

“Honestly, I don’t think she played much different. I think it’s two different surfaces, and I felt like my
level was a little bit higher in Rome, so I think the matchup was better,” Gauff said. “But still, I knew in Rome when I played her, it would be a tough match, and it was.

“I knew today it would be hard, and she’s playing, like, high-level tennis. Yeah, I think that’s what showed today. I think she was the better player today.”

Reigning Roland Garros champion Gauff committed 23 double faults—nearly a full set of doubles—in her opener vs. Danielle Collins yet still squeezed out a 7-5, 4-6 7-6(2) victory relying on her grit and legs to get it done in two hours, 56 minutes. In round two, Gauff clanked 14 double faults fending off Veronika Kudermetova 4-6, 7-5, 6-2. 

Today, Gauff hit just six double faults—one more than the Canadian wild card—but Mboko often handcuffed the top seed slashing returns right back through the middle. Mboko converted all four of her break point chances and frequently controlled the forehand to forehand exchanges.

Gauff skipped Washington, DC to spend time in the Florida heat working on her serve. That shot was suspect in Montreal this week revealing her service game is still very much a work in progress as she heads to Cincinnati before the start of the US Open later this month. 

This match was a rematch of the Rome second round in May when Gauff rallied for a 3-6, 6-2, 6-1 win. 

On the faster Montreal court, Mboko showed she’s one of the few women who can run with the speedy Gauff as she prevailed in some of the crackling crosscourt running rallies. 

Reflecting on that Rome defeat helped Mboko remain focused throughout the second set.

“Yeah, I was actually really thinking about it a lot during the match, especially after I won the
first set. I kind of had flashbacks to when I played her in Rome a little bit,” Mboko said. “I just remember when she kind of came out playing even better and stepped it up a bit better when I played her in
Europe, I was thinking about that.

“I kind of 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.”

Taking the ball earlier than Gauff at times Mboko burned the world No. 2 blasting drives down the line. 

Deadlocked at 4-all in the second set, Mboko cracked a backhand drive down the line then flashed a clenched fist toward her box holding at 30 for 5-4. 

Serving to extend the match, Gauff was down double match point when she hit the slider serve wide. On the full stretch, Mboko flicked a forehand return back into play. Gauff got up to the ball but tried to play a short slice and found the net instead. 

Clad head-to-toe in blue Wilson apparel, Mboko tossed her racquet aside and covered her face with her hands in an eruption of emotion as Montreal fans exploded with cheers.

Gauff was gracious in defeat crediting the teenager with outplaying her.

“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,” Gauff said. “I mean, I don’t know her too well, but I’ve gotten to talk to her a little bit over the course since Rome. I think she has a great support system around her, and I think that’s important when you’re young and on tour.

“Yeah, hopefully we have many more battles, and I look forward to playing her again in the future.”

Mboko is the first Canadian teenager to reach the quarterfinals since Andreescu won the title in 2019—and based on this performance she’s poised to do even more damage in this North American summer hard court season.
