World number three Jessica Pegula had no major problems against Romania's Sorana Cirstea, and the round of 16 was over after one hour and 26 minutes. The score was 2-0 in sets.
Pegula, who was born in New York state, seems to be enjoying the US Open, which is being held in her home state, and so far the tournament has gone according to plan for the third-seeded American. Three of her four matches have been wrapped up in between 57 and 86 minutes.
Jessica Pegula will face either Emma Navarro of the United States or Anna Kalinskaya of Russia in the quarterfinals.
