Ash Barty overjoyed at birth of baby boy Hayden

"Welcome to the world, Hayden!," it read, accompanied by a picture of the new arrival wrapped in a blanket.

The news was acclaimed during the morning at Wimbledon where Barty, a three-time grand slam champion, was feted just two years ago for achieving her tennis dream of winning the singles title.

The following year, she caused a sensation by announcing her retirement from the sport in March less than two months after she had won the Australian Open in Melbourne, breaking a 44-year drought for Australian women players, and was still a completely dominant figure at the top of the game.

Barty then got married to Kissick in July last year in Queensland, and in January announced her pregnancy, declaring: "2023 set to be the best year yet."
