“You were different, and special, and we shared some amazing moments. What’s next for you? Grand Slam champion in golf?! Be happy and enjoy your life to the max xo Simo.”
Petra Kvitova, who faced Barty 10 times on the WTA Tour, was devastated to see the Australian leave the sport.
“Ash, I have no words… actually you are showing your true class leaving tennis in this beautiful way,” Kvitova tweeted. “I am so happy I could share the court with you.. tennis will never be the same without you! I admire you as a player and a person.. wishing you only the best!”
With Barty now retiring from the sport, Iga Swiatek is set to become the new world No 1.
