US Open: Zheng in 5-0 comeback; Gauff, Rybakina, Zverev also in quarters

Home favourite Coco Gauff and world number two Elena Rybakina sailed into the US Open quarterfinals, while China’s Zheng Qinwen mounted another extraordinary fightback to upset six-time Grand Slam champion Iga Swiatek.

Top seed Alexander Zverev beat Italian ⁠Luciano Darderi 6-2, 6-2, 7-6(3) at Arthur Ashe Stadium. The German was surprised to finish before midnight after coming through a couple of five-setters earlier in the tournament.

“I think after 10 hours on court, I just maybe found my rhythm a little bit better, which is helpful because the first two matches ⁠were really not [at a] great level,” Zverev said after his win late on Monday.

“I think I’m going in the right direction, moving forward in the right direction.”

Zverev, who is bidding for a second Grand Slam title after winning the French Open in June, avenged his defeat by Darderi at the Italian Open in Rome earlier this year.

Fourth seed Gauff outclassed compatriot Iva Jovic 6-1, 6-4 to set up a clash with French Open champion Mirra Andreeva for a place in the semis.

“Mirra is someone that I always have ‌tough matches with,” Gauff told reporters. “She’s obviously in a different mindset now at the top of the game coming off of a Grand Slam win … it’s going to be a really athletic, tough match.”

Gauff is the sixth American player into the quarters, joining Jessica Pegula, Emma Navarro, Frances Tiafoe, Alex Michelsen and Ben Shelton.
