“Not bad, strange,” Siniakova said. “I’m working on it, but the important thing is that it needs to go in, and it needs to work in the game.”
But she clearly fits right in at Roland Garros, where she won the doubles title here last year with her compatriot Barbora Krejcikova.
“For sure it brings out my best tennis,” said Siniakova, who followed that win with the doubles title at Wimbledon. “I hope it will continue.”
For Osaka, who will remain No. 1 in the rankings after this tournament, the next stop will be on grass. But she finds herself in a vulnerable position.
Her victory over Serena Williams in last year’s U.S. Open final made her a global star, increasing her sponsorship contracts and earnings exponentially and making her a particular focus of Japanese news coverage. She followed up by winning the Australian Open, showing a rare ability to summon her best tennis on the biggest points.
But she has been unable so far to extend that dominance since splitting with her coach Sascha Bajin unexpectedly after her victory in Melbourne. She retained her fitness coach Abdul Sillah, whose work was also fundamental in her rise to No. 1, and hired Jermaine Jenkins as her new coach. Jenkins previously worked as Venus Williams’s hitting partner and is a former collegiate player at Clemson.
But Osaka has yet to reach another tour final since the Australian Open and has yet to play another semifinal. She retired before her semifinal at the Stuttgart Open in April with an abdominal strain.
