With a straightforward victory over Spain’s Jessica Bouzas Maneiro in the third round of the US Open, American Jessica Pegula further cemented her championship credentials.
In 70 minutes at Arthur Ashe Stadium, the sixth seed completed a dominating 6-3 6-3 victory.
The fact that Pegula has won 89% of her first serve points in New York shows how strong her serve is, since she has yet to lose a set there.
Pegula, who is making it to a Grand Slam quarterfinal for the first time this year, will next take on emerging talent Diana Shnaider.
The 20-year-old Russian, seeded 18th, breezed past Italy’s Sara Errani in a 6-2 6-2 win that saw her land 31 winners.
Shnaider has surged up the world rankings this year after winning her first three WTA Tour titles and reaching the third round of Wimbledon.
Earlier on Saturday, Italian fifth seed Jasmine Paolini beat Kazakhstan’s Yulia Putintseva 6-3 6-4.
French Open and Wimbledon runner-up Paolini, 28, has now made the second week of all four majors in 2024.
She will face Karolina Muchova next after the Czech, who knocked out two-time champion Naomi Osaka in the last round, claimed a comfortable 6-4 6-2 win against Russian Anastasia Potapova.
Muchova reached the semi-finals at Flushing Meadows last year before suffering a wrist injury that required surgery and sidelined her for 10 months.
