Miomir Kecmanovic vs Flavio Cobolli — R64 — Cincinnati Open

Broken to open the third, Cobolli answered in game 2 for 1-1, broke again in game 4 for 3-1, and from there the serve that had underwritten the whole match finished it — 34 of 39 first-serve points won, 13 aces, 39 winners against 12. The second set cost him six double faults. Kecmanovic needed every one of them, breaking in game 9 for 5-4, but the ATP No. 62 converted two of nine break chances all told and won 8 of 39 points against the Italian's first delivery. Three hours 28 minutes of that ends a three-match losing run for Cobolli, his first win since the Wimbledon round of 16, and leaves Kecmanovic without a win in three meetings on record, all on hard. The seventh seed moves on to Alexander Blockx, No. 32 at the time.
