Aryna Sabalenka bids to become the first woman to win three consecutive Australian Open singles titles since Martina Hingis from 1997-99. Sabalenka, seeded first at a Slam for the first time, opened the first Grand Slam of 2025 with consecutive straight-set wins.

Mirra Andreeva is tipped to be a future winner at the majors, but the 17-year-old Russian is looking to the past as she climbs the rankings.

In January 2000, 17 of the WTA top 100 were under 20. In 2025, Mirra Andreeva is the sole teenager — and the last one standing in Melbourne.

Martina Hingis once distanced her outgoing personality from the more reserved nature of Steffi Graf and some other players on tour.

Novak Djokovic and Aryna Sabalenka will step up their bids for tennis history at the Australian Open on Wednesday, where Carlos Alcaraz, Coco Gauff and Naomi Osaka will also be in second-round action.
