Caroline Wozniacki is through to the quarter-finals of the Western & Southern Open in Cincinnati after ending the run of qualifier Ashleigh Barty on Thursday night.
Wozniacki was a comfortable 6-4 6-2 winner as the sixth seed reached the last eight of this tournament for the fourth time in her career.
Barty was impressive early on, breaking Wozniacki to take a 3-1 lead, but it proved a temporary setback for the world number five.
Second seed Simona Halep also advanced in straightforward fashion, beating number 15 Anastasija Sevastova 6-4 6-3.
Fourth seed Garbine Muguruza was given more of a workout as she saved match points to battle past American Madison Keys, beating the 16th seed 6-4 3-6 7-6 (7/3).
Eighth seed Svetlana Kuznetsova beat Spaniard Carla Suarez Navarro 6-2 6-4.
