Nick Kyrgios says the high-profile doping cases involving Grand Slam winners Jannik Sinner and Iga Swiatek are “disgusting” for tennis.
Italian men’s world number one Sinner still faces the threat of a possible suspension after he twice tested positive for an anabolic steroid in March.
Swiatek, also 23, served a one-month suspension after testing positive for a banned heart medication in August, when the Pole was women’s world number one.
“I just think that it’s been handled horrifically in our sport,” said Australian Kyrgios, 29.
“Two world number ones both getting done for doping is disgusting for our sport.
“It’s a horrible look.”
Kyrgios is preparing to make his return to competitive action at the Brisbane International, following an 18-month injury-enforced absence since contesting the Stuttgart Open in June 2023.
In that time, the sport’s leading players in both the men’s and women’s games have become involved in controversy over respective failed tests.
