Summary
- Marta Kostyuk eliminated Coco Gauff in the Cincinnati Open quarterfinals.
- Kostyuk achieved her eighth top-10 win this season, tying for the tour lead.
- The predicted match outcome favored Kostyuk winning in three sets.
Marta Kostyuk, the 10th seed, has advanced to the quarterfinals of the 2026 Cincinnati Open after defeating fourth seed Coco Gauff. This significant victory propels Kostyuk into a key stage of the WTA 1000 tournament held at the Lindner Family Tennis Center in Mason, Ohio.
Kostyuk's path to this quarterfinal included a hard-fought comeback win against Mirra Andreeva. She rallied from a set down to secure a 4-6, 6-0, 6-2 victory in just 93 minutes. This marks Kostyuk's first-ever appearance in the Cincinnati quarterfinals.
Her performance has been exceptional this season, highlighted by her eighth top-10 win, a record she shares on the tour. Gauff, who previously won the Cincinnati title in 2023, reached the quarterfinals by defeating Marie Bouzkova. Despite Gauff's strong defense, Kostyuk's aggressive style was predicted to challenge her in this encounter.
The head-to-head record between Gauff and Kostyuk stood at 3-2 in Gauff's favor, but Kostyuk won their most recent meeting in Doha in 2025, signaling her current strong form. Experts anticipated a competitive match, with a prediction of Kostyuk winning in three sets.
