“It’s the first time I’ve said it out loud, so it’s hard to say but I’m so happy and I’m so ready,” she said in a video posted to Instagram announcing her retirement.
In the video, Barty chats to former doubles partner and good friend Casey Dellacqua, and explains that she knows in her heart that “this is right”.
“Today is difficult and filled with emotion for me as I announce my retirement from tennis,” read the caption for the post.
“I wasn’t sure how to share this news with you so I asked my good friend @caseydellacqua to help me.
“I am so thankful for everything this sport has given me and leave feeling proud and fulfilled.
“Thank you to everyone who has supported me along the way, I’ll always be grateful for the lifelong memories that we created together.”
