Karolína Muchová reaches semifinals in Cincinnati

Czech Karolína Muchová reached the semifinals of the tennis tournament in Cincinnati, after compatriot Marie Bouzková retired from their match with right leg strain while trailing 3-0. Muchová now faces Belarusian second seed Sabalenka, whom she beat in the Roland Garros semi-final earlier this year.

Wimbledon champion Markéta Vondroušová did not make it to the semifinals after losing 6:7, 1:6 to world No. 1 Iza Šwiatek of Poland.
