Muchová has only one hard-court title in her career, which she won at the 2019 Korea Open. Barring that, she has also reached the finals of the 2023 Cincinnati Open and the 2024 China Open. Last year, she had a 25-14 win-loss record on hard courts, with semifinal finishes at the Linz Open and at the Dubai Tennis International as her best results on the surface.
Sabalenka needs to put more first serves in, as her percentage was only 55% in her match against Keys. The Belarusian has struggled to close out matches against Muchová, as the Czech player has shown better tennis in pressure situations. Despite head-to-head, Sabalenka should be able to come through as she is the defending champion, in what should be a close three-set match.
