Osaka withdrew hours before her second match at the year-end championships against fellow grand slam winner Ashleigh Barty and will be replaced by alternate Kiki Bertens of the Netherlands. Osaka had defeated Petra Kvitova in three sets on Sunday in a rematch of January’s similarly gripping Australian Open final.
“I’m disappointed to have to withdraw from the Finals,” Osaka said in a statement released by the WTA. “It has been a great event in Shenzhen, and it’s the biggest WTA event of the year. This is not how I wanted to end this tournament or my season. I look forward to getting healthy and hope to be back here in Shenzhen next year.”
Osaka’s clash with world No. 1 Barty was all set to be a blockbuster. They met earlier in October in the final of a big tournament in Beijing and it didn’t disappoint with Osaka rallying for a three-set victory.
That triumph included, Osaka ends her campaign by winning 11 straight matches. She began the streak by clinching a title in her birthplace of Osaka, Japan in September.
But it hasn’t all been smooth for the baseliner with the often devastating power game.
The shoulder issue was the latest injury to affect the 22-year-old this season, having suffered from minor abdominal and hand complaints during the clay-court swing and a knee injury on the eve of the US Open — where she was the defending champion.
On the court, Osaka sizzled in Melbourne to land a second straight grand slam title and rose to No. 1 in the rankings. But she split from influential coach Sascha Bajin and admitted to struggling with all the heightened expectations.
Away from the hard courts, clay and grass proved to be sterner tests. Escaping in her first two matches at the French Open, Osaka fell in the third round before a first-round exit at Wimbledon. She also admitted that tennis for a time just wasn’t fun anymore.
Osaka was upset by Belinda Bencic in the fourth round at the US Open, 12 months after downing Serena Williams in a controversial final in Flushing Meadows.
She produced the perfect response, only to now be derailed by the shoulder injury.
In Tuesday’s other Red Group tussle, Kvitova faces Bencic. Both hold 0-1 records following defeats to Osaka and Barty, respectively.
