World No. 1 Jannik Sinner defended his Australian Open title on Sunday, comfortably defeating Alexander Zverev 6-3, 7-6(4), 6-3 in the men’s final to secure his third career grand slam win.

Jannik Sinner's three-month doping suspension has divided the tennis world and there are growing calls for the World No.1 to be stripped of his latest grand slam singles title at the Australian Open.

Despite testing positive for a banned substance, Tennis world number one Jannik Sinner has only been banned for three months. Novak Djokovic spoke of "favoritism," while Alexander Zverev called the case "odd.

Anti-doping body lawyer says sanction level against Italian world No 1, which has been criticised by many players, was ‘in the right place’.

Many tennis players and pundits believed that if Jannik Sinner maintained innocence in his doping case, he had no reason to accept a three-month ban under a settlement.
