World number one, Italian tennis player Jannik Sinner, spoke about his doping case following his victory in the final of the Australian Open 2025. Sinner's case is scheduled for a closed-door hearing at the CAS in April.

Jannik Sinner enjoyed another historic accomplishment on Sunday in Melbourne. Sinner defeated Alexander Zverev in straight sets to win the 2025 Australian Open, clinching his third Grand Slam singles title.

Jannik Sinner expressed pride in his continued ability to put his ongoing doping case to one side and dominate on court. The world number one defeated Alexander Zverev 6-3 7-6 (4) 6-3 to successfully defend his Australian Open title and make it three victories in a row at the hard-court grand slams after he also won the US Open.

Alexander Zverev said that Jannik Sinner is as good as Novak Djokovic at his peak and on "a different universe" after the German was well beaten in Sunday's Australian Open final.
