World No 1 Iga Swiatek has been making quick work of opponents at Roland-Garros in 2023. On Monday she got off the court in especially quick fashion, as Lesia Tsurenko retired while trailing 5-1 in the first set of this fourth-round match.

Tsurenko ended Swiatek’s consecutive games won streak at 23 by breaking for 1-4, but after the Ukrainian lost the next game she called it quicks. She appeared to have trouble breathing and may have been feeling dizzy, too, based on the visit from the trainer and doctor.

Swiatek will face American Coco Gauff, the No 6 seed, in the quarter-finals for a rematch of last year’s championship match.

Ahead of her victory, Iga Swiatek defeated Spaniard Cristina Bucsa (6-4, 6-0), American Claire Liu (6-4, 6-0) and Chinese Xinyu Wang (6-0, 6-0).

It was still a productive tournament for Tsurenko, who beat Czech Barbora Krejcikova, the No 13 seed (6-2, 6-4), American Lauren Davis (6-3, 1-0 ret.) and Canadian Bianca Andreescu (6-1, 6-1).
