Magdalena Frech vs Elena Rybakina — R32 — Cincinnati Open

Fifteen break points came and went in the second set for a single conversion, and the low point landed in game 9, when Frech broke for 5-4 and stepped up to serve for a third set. The answer came at once: a break back in game 10 for 5-5. What lasted was the first serve, as Rybakina won 82 percent of her first-serve points against 66 for the 45th-ranked Frech, who saved 14 of the 17 break points she faced and still finished 15 points down across the 159 played. Three match points saved at the other end, 3 hours and 51 minutes on court, and the second seed is into the Cincinnati round of 16 without a set dropped this week, four days on from the Canadian Open final.
