    Naomi Osaka Player Overview

    Naomi heads into her favorite Grand Slam as a dark horse contender. The North American hard-court swing proved that Osaka is once again ready to win. In Toronto, she reached the quarterfinals, where she pushed Elena Rybakina to the limit before losing a tight battle. Citing accumulated fatigue, Naomi made the smart decision to withdraw from Cincinnati, opting to conserve energy and focus on her preparations for New York.

    At the US Open, Naomi does more than just win - she thrives on the big stage. In the opening round, the Japanese star edged past Anastasia Zakharova in an emotional contest (7-6, 7-6), making a statement both with her tennis and her bold designer outfit. The second round saw her showcase championship mettle against the resilient Katerina Siniakova (6-2, 5-7, 6-1). After taking the first set, Osaka eased off slightly in the second, but stormed through the decider, overwhelming the Czech. Right now, Naomi is striking the ball cleanly, her fitness is nearly perfect, and - perhaps most importantly - her trademark mental confidence has returned, the same quality that once brought her two titles in New York.

    Elise Mertens Player Overview

    Elise Mertens is the epitome of consistency on the women’s tour. The Belgian rarely exceeds expectations, but she always delivers a rock-solid level of tennis. Heading into the US Open, she’s in excellent form, having reached the final in Monterrey - a result that underlined her superb physical condition and ability to handle long rallies even in sweltering conditions.

    At Flushing Meadows, Mertens is navigating the draw like a seasoned grandmaster. While she may not possess overwhelming power, her exceptional court sense and movement along the baseline set her apart. In the second round, she kept her composure to dispatch Maria Timofeeva 6-2, 7-6, forcing her opponent into constant risk-taking and errors. Mertens is a master of counter-punching and is outstanding at the net - no surprise given her former world No. 1 ranking in doubles. She’s unfazed by reputations and willing to grind out every point.

    Key factors

    • Elise Mertens has surpassed the 10.5 games mark in six consecutive matches.
    • The average total games in matches involving Elise Mertens stands at 22.3.
    • Over her last 10 matches, Elise Mertens has won 52% of all games played.

    Expected scenario

    Mertens has clearly learned from their recent loss in Toronto. From the very start, she will look to drag Naomi into long, tactical rallies, testing the consistency of the Japanese star’s backhand. If Osaka can maintain a high first-serve percentage and keep her unforced errors in check, her firepower should be enough to see her through. However, if Naomi starts to get nervous and her accuracy slips, Mertens will pounce on any opportunity, potentially turning this clash into a grueling three-set thriller.

    ⭐ Editor's Pick

    Mertens brings too much experience and grit to the table to simply surrender her spot in the fourth round of a Slam, even against Osaka’s formidable firepower. The Belgian excels at keeping rallies alive and, thanks to her outstanding return game, she’s more than capable of putting pressure on her opponent’s serve - especially when Naomi inevitably hits a rough patch during the match. Clearing the 9-game mark is well within Elise’s reach, even in a tight two-set contest, let alone if this turns into a full-blown three-set thriller.

    Osaka has a tendency to get drawn into making unforced errors when her opponent keeps returning everything, and that’s exactly the kind of scenario Mertens thrives in. She knows how to wait for her chances and drag favorites into long, grinding exchanges. With Mertens’ proven track record on the New York courts and her ability to stay patient under pressure, backing her individual games total looks like a logical and reliable pick.
