Osaka Marches On in Toronto
Naomi Osaka continued her impressive hard-court summer on August 8, 2026, by dismantling Elise Mertens in straight sets to reach the fourth round of the National Bank Open in Toronto. The former world No. 1 fired 10 aces and won 88% of her first serves in her previous match, and she carried that momentum into a 6-3, 6-4 victory over the Belgian, extending her winning streak on North American hard courts.
Osaka’s performance in Toronto has been a statement of intent. After a semifinal run in Washington last week, where she fell to Alexandra Eala, the Japanese star has looked sharp, confident, and physically refreshed during the Canadian Open. She has not dropped a set through her first two matches, and her serve has been a particularly potent weapon, reminiscent of the form that carried her to four Grand Slam titles.
The win over Mertens sets up a highly anticipated round-of-16 clash with home favorite Leylah Fernandez, who upset Mirra Andreeva in the previous round—her first Top 10 win of the season. The Canadian has also won her opening two matches without losing a set, setting the stage for a compelling encounter between two of the most dynamic players on tour.
The Stakes: A Return to the Top 10
Osaka’s surge in Toronto is not just about adding another title to her collection; it is about reclaiming her place among the elite. According to recent rankings projections, the Japanese star can climb no higher than No. 11 in the world after this tournament, but a deep run—or a title—would put her firmly in the conversation for a Top 10 return ahead of the US Open.
Since returning from maternity leave in 2024, Osaka has been rebuilding her game and her ranking. Her results have been sporadic, but her performances on hard courts have consistently been her best. She reached the final in Canada last year and has shown flashes of her old brilliance, including a run to the semifinals in Washington just a week ago. Now, with the US Open looming, Osaka is peaking at the right time.
The match against Fernandez is a significant test. Fernandez, a lefty with excellent movement and a fierce competitive spirit, is exactly the kind of player who can frustrate big hitters. The pair are tied at 1-1 in their head-to-head, with each winning on their preferred surface. Osaka’s power and serve will be pitted against Fernandez’s speed and court craft in what promises to be one of the most entertaining matches of the tournament.
Context: A Resurgent Hard-Court Season
Osaka’s 2026 season has been a story of gradual progress. After a solid but unspectacular clay and grass campaign, she has found her footing on the hard courts of North America. Her semifinal in Washington, where she beat Elisabetta Cocciaretto before falling to the in-form Eala, showed she can compete with the tour’s rising stars. In Toronto, she has taken it a step further, dispatching Panna Udvardy and Mertens with authority.
Mertens, a seasoned campaigner, was never able to find her rhythm against Osaka’s relentless pressure. The Belgian had come from a set down to beat Anna Bondar in her opening match, but Osaka’s serve and return were too much. The victory improved Osaka’s head-to-head record against Mertens to 6-3, with the Japanese winning their last two meetings.
Beyond the immediate results, Osaka’s resurgence is a boost for the WTA tour. Her star power and marketability are unmatched, and her deep runs in major tournaments only add to the narrative of a comeback. As she chases her first Grand Slam title since the 2021 Australian Open, every match in Toronto is a step toward that goal.
Perspective: What This Means for the US Open
The Canadian Open is often seen as a barometer for the US Open, and Osaka’s form suggests she could be a major threat in New York. Her game is built for hard courts, and with her confidence growing, she could be one of the favorites to lift the trophy. The draw in Toronto has opened up, with several top seeds already eliminated, and Osaka is taking full advantage.
A match against Fernandez will be a stern test, but it is exactly the kind of challenge Osaka thrives on. Fernandez’s ability to change the pace and use the crowd to her advantage will make this a difficult afternoon for the Japanese star. However, if Osaka serves as well as she has all week, she has every chance of advancing further.
For the broader tennis landscape, a resurgent Osaka adds depth to the WTA’s top tier. With players like Iga Swiatek, Coco Gauff, and Mirra Andreeva establishing themselves as consistent contenders, Osaka’s return to form makes the US Open even more unpredictable and exciting. The prospect of a deep run in Toronto—and potentially a title—would send a clear message to her rivals: Naomi Osaka is back.
As the tournament heads into the quarterfinals, all eyes will be on Osaka. Her journey from the parking lot tears after a US Open loss—a moment she recently recalled—to the brink of a Top 10 return is a testament to her resilience. For now, she remains focused on the next match, but the tennis world is watching with anticipation. The Canadian Open third-round clash was just the beginning; the real test lies ahead.
