SHENZHEN, China — Naomi Osaka has withdrawn from the WTA Finals because of a right shoulder injury ahead of her scheduled round-robin match against top-ranked Ash Barty.

Alternate Kiki Bertens will take Osaka’s place against Barty later Tuesday.

“I’m disappointed to have to withdraw from the finals,” Osaka said in a statement. “This is not how I wanted to end this tournament or my season (but I look forward to getting healthy and hope to be back here next year.”

Barty opened the round-robin stage with a 5-7, 6-1, 6-2 win over Belinda Bencic.
