"I'm speechless... She's an absolute champion and I knew I had to step up my game," said Anisimova, who is unbeaten in her eight matches since the start of the year. Osaka added: "I fought for every point. I can't be sad about that... I feel like I grew a lot in this match. The last match that I played in New York I think I had a completely different attitude... Of course I lost, but I'm happy with how it went."

"Today's match was very tough, I had to dig deep to get this win, so I'm very happy and proud of myself. I'm never going to leave without a fight and I'm happy to show that on the court," Krejcikova said.

1221 AZARENKA BRUSHES ASIDE SVITOLINA Two-time Australian Open winner Victoria Azarenka handed number 15 seed Elina Svitolina a comprehensive 6-0 6-2 defeat to advance to the fourth round.
