Tennis's first Grand Slam of 2025 kicks off on Saturday, with the sport's heaviest hitters convening in Melbourne for the Australian Open.

World No. 1 Aryna Sabalenka — the reigning back-to-back Australian Open champion — enters as the tournament's first overall seed for the first time. However, she'll see stiff competition by way of No. 2 Iga Świątek, No. 3 Coco Gauff, and No. 4 Jasmine Paolini.

"For me being the one to chase... I like that feeling," Sabalenka told reporters this morning. "That's what drives me and helps me to stay motivated because I know that I have a target on my back."

Tough roads to the trophy litter Australian Open draw

Each top contender faces a tricky tournament draw, with upset potential lurking in every quadrant.

Sabalenka could meet 2024 Olympic gold medalist and WTA Finals runner-up No. 5 Zheng Qinwen as early as the quarterfinals, as long as she survives a first-round matchup against 2017 US Open winner Sloane Stephens.

Reigning WTA Finals champion Gauff's quadrant is in Sabalenka's half of the field, setting up a possible rematch of last year's semifinal. As for the 20-year-old US star's path, earlier rounds could see Gauff contending with tough competitors like 2021 Australian Open champ Naomi Osaka, 2024 US Open semifinalist Karolína Muchová, and 2024 US Open finalist No. 7 Jessica Pegula.

Świątek and Paolini could also meet in a semifinal, though fellow top competitors No. 8 Emma Navarro and 2020 Australian Open winner Ons Jabeur stand in Świątek's way while No. 10 Danielle Collins and 2022 Wimbledon champion No. 6 Elena Rybakina have been drawn into Paolini's quadrant.
