Melbourne – Defending champion Jannik Sinner and co-title favorite Iga Swiatek naturally had to answer questions about their doping cases in the run-up to the Australian Open. There was a lot of criticism that it took a long time to inform the public about the incidents surrounding the tennis stars. It was shorter for Swiatek, but the Pole said in Melbourne that she had considered going public early herself. Sinner, on the other hand, has known since Friday how his case will continue.
