Naomi Osaka vs Suzan Lamens preview

Naomi Osaka will face Suzan Lamens in the second round of the Japan Women's Open.

Osaka has had a good season so far. After a title-winning run in Saint-Malo, she reached the finals in Cincinnati and semifinals in New York. She also participated in the China Open but lost to Aliaksandra Sasnovich in the second round.

Osaka entered the Japan Women's Open after a second round exit in Wuhan. She started her campaign by cruising past Sonobe Wakana in the first round, 6-0, 6-4. The former World No. 1 is among the favorites to win this year.

Osaka's recent results showcase her determination to succeed on tour. The four-time Grand Slam champion has yet to win a title (tour level) in 2025, but has been close to making her mark. She has played an aggressive brand of tennis and is known for her calm demeanor on the court.

Lamens, on the other hand, has shown glimpses of her top potential this year. She's started well at most events, but lacks the killer instinct in the difficult rounds. The 26-year-old old has a versatile all-around game and great anticipation skills on the court.

No points for guessing that Osaka will be a clear favorite to win this bout. The top seed has a better record on hardcourts and should be able to solve this round.

Pick: Osaka to win in straight sets.
