Osaka falls to Teichmann in third-round Cincinnati shocker
Naomi Osaka lost to an opponent who has struggled with several injuries this season but is now back to health.
CINCINNATI - Naomi Osaka has no regrets over her stunning third-round loss Thursday at the ATP and WTA Cincinnati Masters to Swiss wild card Jil Teichmann.
The four-time Grand Slam champion went down 3-6, 6-3, 6-3 to the world number 76 and admitted after the upset that her Tokyo Olympic third-round loss was on her mind.
"I was doing all I was supposed to do," the Japanese world number two said. "In the second and third sets I was too defensive.
"I learned a lot from this match - I can sleep at night."
Osaka lost to an opponent who has struggled with several injuries this season but is now back to health.
"I knew inside I had this level and I was able to show it on court," said Cincinnati quarter-finalist Teichmann. "This week things are working out. I needed to be patient and here I am."
Osaka stayed low-key throughout the post-match media sessions she says she dreads, answering questions and seeming to meekly accept thr loss in her final tuneup for the US Open, which begins 30 August.
"I have high expectations of myself but there was nothing more I could do to win this match," Osaka said.
"I'm almost glad I lost as it gives me so many things to work on in my game.
"I just hope the results come in time for the US Open."
Osaka said her only regret was not winning more that $24,200 in prize money to donate in aid of the earthquake recovery effort in Haiti, her father's homeland.
"I'm happy, but sad that I didn't go further," Osaka said. "But I think I raised awareness. I'm glad we were able to contribute something."
Tournament officials said they would match her donation after Osaka promised to give all of her prize money to the cause.
Teichmann took just over two hours to defeat Osaka, breaking the Japanese star six times, three in the final set.
Osaka made 41 unforced errors in the match while hitting only 17 winners while Teichmann struck 21 winners against 29 unforced errors.
"Literally, I'm shaking right now," Teichmann said just after the match.
Osaka has had a rough ride since withdrawing during Roland Garros over emotional issues and skipping Wimbledon. She has played only two hardcourt preparation matches since the Olympics.
TSITSIPAS RALLIES TO WIN
Men's second seed Stefanos Tsitsipas needed a fightback to tame Italian Lorenzo Sonego 5-7, 6-3, 6-4. The Greek improved to 47-13, increasing his ATP season match-win lead.
Tsitsipas said saving three break points in the first game of the second set changed the match trajectory.
"I'm glad I overcame that obstacle," he said. "I stayed in and waited for opportunities to present themselves. A fighting spirit was very crucial."
Top seed Daniil Medvedev reached the quarter-finals with a 6-3, 6-3 victory over fellow former champion Grigor Dimitrov.
The Russian world number two stretched his record against the Bulgarian to 3-1. Medvedev won the Cincinnati title in 2019 while Dimitrov took the trophy in 2017.
Medvedev, the champion in Toronto last weekend, will next face Spaniard Pablo Carreno Busta, who defeated ninth seed Hubert Hurkacz of Poland 7-6 (8/6), 7-6 (7/3).
"What makes it tough, it's two weeks in a row against the best players in the world," Medvedev said. "I'm still young, healthy and feeling 100%, so that is why I want to try and do it."
Third-seeded Olympic gold medalist Alexander Zverev defeated Argentine Guido Pella 6-2, 6-3 in 73 minutes while never facing a break point.
Women's top seed Ashleigh Barty of Australia powered into the quarter-finals 6-0, 6-2 over Victoria Azarenka.
"I felt like I was able to win a lot of those big points," Barty said. "Getting ahead early in games was really helpful."
Barty improved to 13-1 over top-20 opponents this season and will next face off against fellow French Open champion Barbora Krejcikova, who beat Garbine Muguruza 6-1, 6-7 (5/7), 6-2.
