Marta Kostyuk vs Sofia Kenin — R64 — Cincinnati Open

The chances taken separated them, not the points won. Kostyuk converted four of six break points while Kenin cashed three of 11, in a match whose total-points margin came to five, 100 to 95. The serve made the turn: Kenin's first-serve points won fell to 52 percent in the decider against Kostyuk's 80, four of the winner's nine aces arriving in that set. Then it nearly slipped. The 10th seed broke in game 9 for 5-4, was pulled back to 5-5 in game 10, and needed a second break to close after two hours and 22 minutes, Kenin having saved two match points before the finish. It squares their meetings on record at 1-1, answering a Dubai loss that went the distance in February 2025.
