Can the top seed keep the momentum going in her home tournament?
Top seed Naomi Osaka will feature in the Round of 16 at her home event in the WTA Japan Women’s Open in Osaka on Wednesday. The 27-year-old Grand Slam champion is set to battle Suzan Lamens of the Netherlands in the marquee clash on Centre Court. The winner of this clash will face either Jessica Bouzas Maneiro or Jaqueline Cristian in the quarterfinals. With the help of our very own BetMGM, we will give you all the stats and odds related to the encounter today.
After an encouraging start to the 2025 season at the ASB Classic where she was the runner-up, Naomi Osaka struggled to get going. The Japanese superstar picked up a vital WTA-125 title in Saint-Malo; however, she failed to stamp her authority at the majors. It was the Canadian Open in Montreal that sparked a comeback trail for Osaka. The four-time Grand Slam champion beat the likes of Ostapenko, Svitolina and Tauson, before falling short vs Mboko in the final. Another impressive run to the semifinals of the US Open left the World No. 16 with a record of 33-15 in 2025.
On the other hand, Suzan Lamens entered the tournament with a 50% success rate so far. The Dutch starlet achieved her career-best Grand Slam performance at all four majors this year. Despite failing to add to her tally of championships, Lamens’ semifinal finish at the Open de Rouen and quarterfinals at the Libema Open and Korea Open were apt showcases of her immense ball-striking talent. The 26-year-old, who broke her three-match losing streak in the Round of 32, will be hoping to make a maiden entry into the Top-50 in Osaka.
Naomi Osaka leads the head-to-head against Suzan Lamens by 1-0. They faced one another at ‘s-Hertogenbosch in 2024, where the two-time US Open winner earned a straight sets win.

Osaka is a strong favorite due to her power and precision. She will look to take control of baseline exchanges right from her serve, and her fearless approach should get her over the line. While Lamens impressed in her opener against Arango, she will not get time on the ball to dictate play against Osaka. The No. 1 seed faced merely three break points in Round-1, and won 83% and 75% points on first and second serves.
Prediction: Naomi Osaka in straight sets.
Osaka (1/6) is the favorite and Lamens (4/1) is the minnow for the WTA Japan Open 2025 Round of 16 match-up. According to the implied probability on the money line, the former World No. 1 has a 77% chance of emerging victorious. Here are the odds (as per BetMGM):
