Amanda Anisimova vs Jessica Pegula — QF — Cincinnati Open

Efficiency on return belonged to the player who lost. Anisimova converted all five break points she manufactured while Pegula needed seven chances to take four, and the ninth seed saved a match point in game 10 to break back for 5-5. It bought her a tiebreak and nothing more, the points ledger finishing dead level at 95-95 over 2h 14m. Pegula stays unbeaten in five meetings on record and moves into the Cincinnati semifinals having now been taken past a set in back-to-back rounds, Cirstea the last to try.
