Iga Swiatek, a self-described “control freak,” is taking new precautions — including holding on to extra samples of medicine she takes, in case they need to be tested at some point — after a doping case she describes as probably the worst time in her life.

Iga Swiatek says that her positive doping test was abstract to her as she did not know that medicine could be contaminated.

It is a topic that shadowed tennis in 2024 and is still a talking point as the 2025 Grand Slam season opens at the Australian Open on Sunday (Saturday EST): doping and the cases involving Jannik Sinner — which is still not resolved — and Iga Swiatek.

Jannik Sinner will launch his Australian Open title defence under a stubborn doping cloud but the whiff of scandal may do little to halt the Italian juggernaut. Sinner remains the man to beat at Melbourne Park even as doping officials seek a two-year ban for the world number one for failing two drugs tests last March.

Defending champion Jannik Sinner and 10-time Australian Open winner Novak Djokovic have landed in opposite sides of the draw for the season’s first major, ruling out a replay of last year’s semifinal

Aryna Sabalenka will bid for a third Australian Open title in succession as if she was going for her first, having dropped the defending champion mindset to great success last year.

World number one Aryna Sabalenka said Friday she wants to "put my name into history" by winning a third straight Australian Open title, but is aware she "has a target on her back".

World No.1 Aryna Sabalenka is enjoying life as she started the year by winning the 2025 Brisbane International title and is now eyeing to bag her third Australian Open title.
