Azarenka advances to Berlin semis

BERLIN, June 21 (AFP): Former Wimbledon champion Elena Rybakina pulled out of Friday's Berlin WTA tournament while trailing Victoria Azarenka in the quarter-finals.
Rybakina, the third seed, was 1-3 down and visibly struggling in the first set before pulling up at 15-all on her serve.
The 2022 Wimbledon champion also withdrew from Rome last month citing illness before the quarter-finals, just before the French Open.
The 25-year-old Russian-born Kazakh was stunned by Italian Jasmine Paolini in the quarter-finals of Roland Garros.
She will bid to recover for Wimbledon starting on July 1 where she lost in the quarter-finals last year to Tunisian Ons Jabeur.
Former number one Azarenka, 34, will play either compatriot Aryna Sabalenka, the second seed, or Russian Anna Kalinskaya in Saturday's semi-final.
