No. 4 seed Jessica Pegula, the 2024 US Open runner-up, advanced to the quarterfinals at Flushing Meadows for a second straight year by defeating fellow American Ann Li 6-1, 6-2 in just 54 minutes on Sunday.
Pegula, who opened the day session at Arthur Ashe Stadium, hasn't dropped a set at this year's tournament, and only once was even kept on court for more than 1 hour, 15 minutes.
The three games she dropped against Li were her fewest in a US Open match for her career. Through four rounds, Pegula has dropped just 17 games, her fewest en route to any of her eight major quarterfinal appearances.
"Very good match for me today," the Buffalo native said. "Probably the best match, honestly, I've played since before Wimbledon from the start to finish. So that was encouraging."
Pegula had been 0-6 in Grand Slam quarterfinals before upsetting Iga Swiatek in that round last year. She went on to reach the final, where was defeated by Aryna Sabalenka.
The 58th-ranked Li, one of five American women to reach the round of 16, was the highest-ranked player Pegula has faced in the tournament, but the 25-year-old was overpowered in her first appearance in the round of 16 in a major. Pegula broke her all four times she served in the 25-minute first set, and she had just five winners against 19 unforced errors in the match.
"I was just hitting the ball, doing everything well, executing my strategy very well and got through it pretty quick," Pegula said.
Pegula has excelled at tournaments in her home country, with her 85 WTA match wins on U.S. soil since the start of 2020 the most by any player on the women's tour.
She will face either two-time Grand Slam champion Barbora Krejcikova or another American, Taylor Townsend -- who upset No. 5 seed Mirra Andreeva in the previous round -- on Tuesday.
