Second-seeded Ash Barty advanced to the round of 16 at the US Open with a 7-5, 6-3 victory over Maria Sakkari.
Barty, the reigning French Open champ who faced tough tests in her first two rounds, employed a steady baseline game and took advantage of 39 unforced errors from the 29th-ranked Sakkari.
This is the second year in a row Barty has advanced to the final 16. She next faces the winner of the match later Friday between 18th-seeded Qiang Wang and Fiona Ferro.
