In China's capital city, pulled out of Osaka in the quarter-finals after a big comeback in the last two sets of the Canadian Bianca Andreescu (RESULT 6), and just last month, the victor of the US Open: 5-7, 6-3, 6-4, after a battle of more than two hours. "I have to learn from her, too".
Osaka will next face Bianca Andreescu in a meeting of the last two U.S. Open champions.
"It meant a lot because I feel like people counted me out after the Europe thing", Osaka said, referencing how she performed on clay and grass this year, losing in the third round of the French Open and in the first round at Wimbledon and not reaching a final.
"I've always had tough matches against her", Wozniacki said post-match.
"I forgot how it felt and honestly it sucks, I didn't miss it", Andreescu said after her first loss since the Miami Open in March in a run that included her stunning victory over Serena Williams in the US Open final last month.
Osaka, 21, had her 10th and final ace on her third match point to prevail.
"I was really nervous on the first couple (of match points), and I just tried to breathe", Osaka said.
The Japanese star captured her second title of the season on home soil at the Toray Pan Pacific Open (Osaka) and reached the semifinal stage on three occasions at Brisbane International, Porsche Tennis Grand Prix in Stuttgart and the China Open in Beijing, now in progress.

"I just told her that she was an unbelievable player".
Australian Start champion Osaka fired 10 aces, 31 winners and won 78% of her first carrier parts in a discover-saw come throughout that had a whole of 11 breaks of assist.
"I just told her that she was an wonderful player", Osaka told interviewers. "I think then with some pressure and playing better all the time, it's good for me".
