Thanasi Kokkinakis announced his withdrawal from the Australian Open singles event on Thursday.
“Unfortunately after speaking with my team and doctors I have made the decision to pull out of the @AustralianOpen singles,” Kokkinakis wrote on Instagram Stories. “After an incredibly tough year this was the event I was looking forward to the most but I’m not ready yet. I’m doing everything I can every day to be back to 100%.”
Kokkinakis played his first singles match in nearly a year last week at the Adelaide International, where he defeated Sebastian Korda in a final-set tie-break.
But throughout the match, the Australian struggled with his right shoulder on the back of pectoral surgery last February. He withdrew from Adelaide on Wednesday.
The 29-year-old hopes to compete in doubles at Melbourne Park. He won the title with Nick Kyrgios in 2022.
“We will still try and step out for the doubles and have some fun,” Kokkinakis wrote. “Thank you to everyone who supports me.”
