Yulia Putintseva vs Liudmila Samsonova — R128 — Cincinnati Open

It ended in game 12 of the third, a break for 7-5 that landed three hours and nine minutes after the opening ball, and the shape of that game was the shape of the whole match: Samsonova took every break point she was handed, four from four, while Putintseva needed six chances to collect her four. Putintseva won more points and lost. She finished with 112 of the 221 played and nothing to show for it, because Samsonova coughed up 10 double faults, three of them in the decider, and still won 75 percent of her first-serve points to the 82nd-ranked Kazakh's 65. She had come in 0-2 against Putintseva on record, both meetings on hard; that ledger is settled. Coco Gauff, the No. 4 seed, is next.
