Aryna Sabalenka has been showcasing consistently powerful form since the end of last season, with just one loss in her last ten matches. In Brisbane, the Belarusian remains flawless in sets, conceding an average of only five games over a span of four matches.

Marta Kostyuk Player Overview
Marta Kostyuk set her sights on breaking into the top 10 of the world rankings as her goal for the year, and in Brisbane, she's proving that was no idle talk. In her last three matches, the Ukrainian has shown she can compete on equal footing with top 10 WTA players. Her journey has included victories over Amanda Anisimova, Jessica Pegula, and Mirra Andreeva-ranked 3rd, 6th, and 9th in the world, respectively. Impressively, Kostyuk didn't drop a single set against these high-ranking opponents. While her average ace count is noticeably lower than Sabalenka's, at just 1.8 per match, she makes up for a less powerful serve with high efficiency on return and an ability to handle pressure: winning 54% of break points. Double faults remain an issue (24 in her last ten matches), but her speed and court positioning often allow her to recover from such mistakes.

⭐ Editor's Prediction
Analyzing the form and playing style of both tennis players, it's clear that Aryna Sabalenka might face a tough challenge. Her serve and aggressive approach usually ensure dominance on the court, but her struggles with break points could be an issue against Kostyuk, who excels in capitalizing on these opportunities. Sabalenka's main advantage lies in her ability to dictate the pace of the game with powerful shots and her physical presence. However, the Ukrainian's agility and smart court positioning have consistently allowed her to overcome similar challenges, even against higher-ranked opponents in Brisbane. In Sabalenka's last four finals, at least 20 games were played. We believe Marta can pose certain challenges to the world number one, making this match likely to extend. Our prediction: total games over 19.5.
