A revenge for Anisimova who was defeated with 6–0, 6–0 the last time the two met – in the final in Wimbledon in July this year.
To come back from Wimbledon in that way is really special for me, says Anisimova.
I feel that I worked so hard to turn it around after that. I knew that I would need to dig really deep. It was such a tough match, really a struggle for me, she continues.
The 24-year-old Anisimova will play against the two-time former US Open champion Naomi Osaka, Japan, or the Czech Karolina Muchova for a place in the final.
