It proved to be a challenging day for Naomi Osaka, contrasted by a truly remarkable one for Canadian prodigy Victoria Mboko.
Mboko, now 18, staged a stunning rally to overcome the four-time Grand Slam victor by scores of 2-6, 6-4, 6-1 in Thursday’s Canadian Open final, capturing her inaugural WTA title amidst passionate hometown support in Montreal.
By triumphing over Osaka, Coco Gauff, Elena Rybakina, and Sofia Kenin during the competition, Mboko has reportedly secured the distinction as the second-youngest competitor ever to conquer four Grand Slam champions in a single tournament, trailing only Serena Williams in that remarkable achievement.
A victory for Osaka would have marked her first WTA title since the 2021 Australian Open, an absence stretching 1,629 days. The journey back to the pinnacle remains ongoing after an extended break during which she addressed injuries and welcomed her firstborn.
“I extend my gratitude to Naomi for a truly exceptional match,” Mboko conveyed during her victory speech. “I’ve always admired her since my younger years. It’s a privilege to compete against such an incredible athlete.”
Mboko was a mere 12 years of age when Osaka clinched her first Grand Slam title at the 2018 US Open.
Both competitors entered the match brimming with anticipation. For Osaka, it represented her first WTA final appearance since the 2022 Miami Open, an opportunity to reaffirm her resurgence among tennis’ elite. Mboko, currently ranked 85th by the WTA, enjoyed the backing of local fans, having previously stunned No. 1 seed Gauff in straight sets during the Round of 16 and securing a comeback victory against Rybakina, another prominent player, in a three-set semifinal.

Osaka displayed dominance throughout the initial set, but the tide shifted decisively early in the second. Growing visibly discouraged following a break, she struggled to regain composure amidst the enthusiastic support for her Canadian opponent.
She faltered with a mistake-filled performance in the second set, which worsened in the third. The set was characterized by a series of unforced errors and dispirited body language, while Mboko progressively built momentum. At one juncture, Osaka received a warning for angrily striking a ball off the court after a fault on break point, then followed with a missed volley, further tilting the advantage toward Mboko.
It wasn’t necessarily Mboko’s finest showing — she committed 13 double faults and relied somewhat on Osaka’s frustrations — but she performed adequately to overcome an opponent seemingly battling internal demons just as much as the person across the net.
Osaka has demonstrated advancement since her return at last year’s Australian Open. She achieved two match victories at both the Australian Open and Wimbledon this year, has accumulated $725,727 in prize money, and attained the No. 49 position in the WTA rankings, with a likely rise in ranking following her final appearance.
However, this is not reflective of the standards she established half a decade prior, when she reigned as the premier hardcourt player with a promising future ahead. Osaka’s disappointment was evident during the trophy presentation, her voice wavering during a brief address to the crowd, where she did not specifically acknowledge Mboko.
She may have the opportunity for a quick rebound, as she is slated to participate in the Cincinnati Open commencing this weekend. Mboko is also listed in the tournament draw, with the US Open following soon after.
