Fourth-seeded Angelique Kerber of Germany reached the semifinals of the Toray Pan Pacific Open when fifth-seeded Madison Keys withdrew in the decisive set on Friday at Osaka, Japan.
Kerber led 6-4, 4-6, 2-1 when Keys couldn’t continue due to an apparent foot injury. Kerber had 18 winners and 13 unforced errors, while Keys hit 39 winners and committed 33 unforced errors.
The match was the only one completed due to weather conditions as Russian Anastasia Pavlyuchenkova led Japan’s Misaki Doi 2-0 in the first set when play was halted. That match is scheduled to be completed on Saturday, when postponed quarterfinal matches between top-seeded Naomi Osaka of Japan and Kazakhstan’s Yulia Putintseva and ninth-seeded Belgian Elise Mertens and Italy’s Camila Giorgi will also be made up.
