Azarenka has reached six AO quarterfinals, three semifinals, and two finals, cementing herself in the top echelon of tournament performers.

Now 35, Azarenka is entering the twilight of her career, but impressively maintains a top-25 ranking.

Stan Wawrinka

‘Stan the Man’ put himself on the map at the Australian Open.

Known for his lengthy encounters with Novak Djokovic, a four-hour battle in the 2014 quarterfinal – which Wawrinka won 9-7 in the fifth – avenged an epic loss to the Serbian a year earlier, and he went on to win his maiden Grand Slam title five days later.

The 39-year-old has been offered a main draw wildcard at AO 2025, yet despite a ranking outside the top 100, Wawrinka finished 2024 in scintillating fashion, reaching the semifinals at the Stockholm Open, where he defeated Andrey Rublev and Brandon Nakashima. 

Expect him to carry this form into his 19th campaign at Melbourne Park.

Roberto Bautista Agut

Roberto Bautista Agut has been a five-set master at Melbourne Park. 

Of his 35 AO matches, 12 have gone the distance – and he boasts an 8-4 record. Most notably, Bautista Agut won consecutive five-setters in 2019 against Andy Murray and John Millman.

Bautista Agut reached the last eight in that campaign – his first Grand Slam quarterfinal after several fourth-round appearances.

Turning 37 in April, the world No.51’s five-set track record means there could be plenty of intrigue around his matches at AO 2025.

He opens against Canada’s Denis Shapovalov.

Danielle Collins

Following her loss to Iga Swiatek in the second round of Australian Open 2024, Danielle Collins revealed that it would be her final season.

“I feel like I’ve had a pretty good career. There has certainly been ups and downs to it,” she said. “I have other things that I’d kind of like to accomplish in my life outside of tennis, and would like to be able to kind of, you know, be able to have the time to be able to do that.”
