BERLIN — Elena Rybakina retired from her quarterfinal in Berlin, seemingly because of illness.
The 2022 Wimbledon champion was trailing Victoria Azarenka 3-1 in the first set at the grass-court Ladies Open and stopped playing after her double fault made it 15-15 in the fifth game.
Rybakina sat on her bench, put her hands to her face but didn’t wait for a medical evaluation. After 40 seconds, she got up and quickly jogged to the locker room.
Wimbledon champion Marketa Vondrousova retired from her match in Berlin because of a leg injury.
First-round play begins at Wimbledon on July 1.
Former No. 1 Azarenka, a two-time Australian Open champion, will face second-seeded Aryna Sabalenka or Anna Kalinskaya in the semifinals.
Fourth-seeded Jessica Pegula led Katerina Siniakova 7-6 (2), 3-6, 4-2 when rain interrupted play.
The other two quarterfinals were moved: Sabalenka vs. Kalinskaya; and top-seeded Coco Gauff against Ons Jabeur.
