It’s 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 — the doping cases involving Jannik Sinner and Iga Swiatek.
Both spent much of last year at No. 1, and Sinner still will hold that spot at this Australian Open, one of two major trophies he won over the past 12 months.
