MELBOURNE, Australia — Defending Australian Open champion Naomi Osaka withdrew from her semifinal match Saturday at a WTA tournament with an abdominal injury, allowing her opponent Veronika Kudermetova to advance to the final on a walkover.
“I had a lot of fun playing here in Melbourne. Unfortunately I have an abdominal injury which I need to rest and prepare for the Australian Open,” Osaka said in a statement issued by Tennis Australia.
“Sad to withdraw due to injury from my match today, my body got a shock from playing back to back intense matches after the break I took,” Osaka added later on Twitter. “I’ll try to rest up and I’ll see you soon!”
The Australian Open begins on Jan. 17.
