Victoria Mboko can continue to get better after reaching the final of the Canadian Open.
Mboko has beaten Coco Gauff, Elena Rybakina and Sofia Kenin en route to reaching the final of her home WTA 1000 tournament.
Her latest victory over Rybakina was perhaps the most dramatic, especially as Mboko hurt her wrist when falling to the ground.
Despite Mboko’s breakthrough run, she has been told that an area of her game still needs improvement.

Rennae Stubbs says she would change things about Victoria Mboko’s serve
Rennae Stubbs knows the importance of a good serve, as a former doubles world number one and six-time Grand Slam doubles champion.
She also has experience coaching one of the greatest servers in the history of tennis, with Stubbs having helped Serena Williams for a brief period.
After watching Mboko beat Rybakina, 1-6 7-5 7-6(4), Stubbs was full of praise for the Canadian teenager, but admitted that she still thinks her serve could use some technical improvements.
Stubbs wrote on X (formerly known as Twitter), “This kid is the REAL deal. She has so much raw ability. Power, grit, great mover, huge serve, just amazing upside. There are some technical things on serve I would clean up, but damn she is going to win a lot of matches on the WTA Tour!”
While she did not specifically mention Mboko, another social media post she made 20 minutes earlier suggested what Stubbs may think is wrong with the 18-year-old’s serve at the moment.
It read, “Dear coaches! Teach a high elbow on serve. You’re welcome and thank you.”
Victoria Mboko’s service statistics at the Canadian Open this year
Although Stubbs has pinpointed these improvements for Mboko to make, it has generally been a weapon for her at the Canadian Open.
This was particularly evident in the opening couple of rounds, where Mboko was hitting a double-digit number of aces.
Those numbers have slightly dwindled as the tournament has progressed, with Mboko having been broken seven times by Rybakina.
| Victoria Mboko’s serve at the 2025 Canadian Open | |
| Average Aces per match | 6.8 |
| Average Double Faults per match | 5.8 |
| Average First Serve % | 63.7% |
| Average First Serve Win % | 69.7% |
| Average Second Serve Win % | 46.5% |
| Average Games Broken per match | 2.7 |
Mboko will hope that she can serve well in the Canadian Open final when she will play Naomi Osaka, who has one of the best serves on the WTA Tour.
This will be a first-time meeting between Mboko and Osaka, with a huge prize on the line in Montreal.
