Cori Gauff and Marta Kostyuk, two players in top form, are set to face off in the WTA Cincinnati quarter-finals. This will be the sixth time they are meeting, and our prediction backs this to require a deciding set.

Fourth seed Gauff has the head-to-head advantage in this fixture, though she lost their most recent meeting, in Doha last year. She will be out to stop Kostyuk from levelling the scores, having booked her place with a straight-set win over Marie Bouzkova.

She has only dropped one set in Cincinnati and will be playing her eighth quarter-final of the season here, having won five of the earlier seven. With her fourth-round win, she has compiled a 37-13 record for the season.

Kostyuk’s mission in this encounter entails stopping Gauff from winning her second title here. For the Ukrainian, this is the fourth Cincinnati appearance, and the 10th seed has already surpassed her previous best – the third round.

In Cincinnati she is seeking a third title of the season, having earlier conquered the Rouen and Madrid events. Kostyuk has dropped a set twice in Cincinnati, most recently in her win over Mirra Andreeva.

The 24-year-old hasn’t lost a quarter-final this season; her 5-0 run so far makes her a tough opponent for Gauff. She arrives for this encounter placed 11th in the live ranking.
