Elena Rybakina underlined why she is the new title favourite with a dominant performance against Anna Kalinskaya under the roof on Centre Court, before her opponent retired injured.
With 2022 champion Rybakina leading her fellow 25-year-old 6-3 3-0, Kalinskaya left the last-16 match in tears after she was unable to recover from a wrist injury.
The Russian 17th seed had taken a medical timeout midway through the first set.
Russian-born Kazakh player Rybakina is the highest seed left in the women’s draw and will face Svitolina next.
Rybakina is the only former Wimbledon champion left in the women’s draw, while her bid has been strengthened by Iga Swiatek and Coco Gauff featuring in a flurry of big names knocked out over the weekend.
The fourth seed dropped serve in the first game of the match and trailed 3-1 in the opener, but she then won five consecutive games, with two breaks to love, to take the first set.
She broke at the first opportunity in the second, defended a break-back point, and broke again to set up a commanding lead.
At that point Kalinskaya, who had been visibly struggling since the middle of the first set, decided not to risk further injury and forfeited the match.
On court one, Latvian 13th seed Jelena Ostapenko beat unseeded Kazakh Yulia Putintseva 6-2 6-3 with a dominant performance.
Former French Open champion Ostapenko’s powerful hitting from the baseline proved too much for Putintseva – the player who knocked out Swiatek.
It means the 27-year-old Ostapenko will line up in a third Wimbledon quarter-final.
She will face American 11th seed Danielle Collins or Czech 31st seed Barbora Krejcikova in the last eight.
