WATCH: Ashleigh Barty and her baby boy Hayden attend Brisbane International clash between Sebastian Korda & Yannick Hanfmann

Ashleigh Barty was in attendance at the Brisbane International along with her infant son and her mother.

The Aussie retired from tennis in 2022 just months after winning the Australian Open. Barty did not drop a single set en route to her triumph, which made her the first woman from her country to win the Melbourne Major since Chris O'Neil in 1978.

The former World No. 1 married her longtime boyfriend Garry Kissick in July 2022 and gave birth to the couple's son Hayden a year later.

Ashleigh Barty was spotted at the first-round match between Sebastian Korda and Yannick Hanfmann at the Brisbane International. Present with the Aussie were her son and her mother.

The match between Korda and Hanfmann saw the latter beat the fifth-seeded American 6-4, 7-5 to book his place in the second round, where he will face James Duckworth, who beat JJ Wolff 6-3, 6-4.
