Naomi Osaka withdrew from the season-ending WTA Finals due to a shoulder problem on Tuesday 29th October.
Osaka, who retired in last year’s edition of the lucrative year-ender with a hamstring injury, had been due to play world number one Ashleigh Barty later on Tuesday.
Naomi Osaka said she’s disappointed to have withdrawn from the Finals, and added It has been a great event in Shenzhen, and the biggest WTA event of the year.
Osaka added that this isn’t how she wanted to end the tournament but look forward to getting healthy and hope to be back in Shenzhen next year.
Osaka had started the $14 million round-robin tournament with a tough three-set victory over Petra Kvitova on Sunday to extend her winning streak to 11 matches after titles in Beijing and Osaka.
Osaka had been determined to make amends for a disappointing WTA Finals debut last year when her winless campaign ended with her retiring in tears against Kiki Bertens due to a hamstring injury.
World number 10 Bertens will replace Osaka for the remaining matches and plays Barty in Red Group action on Tuesday.
