Jannik Sinner's case was "a million miles away from doping", says World Anti-Doping Agency general counsel Ross Wenzel.

Doping Agency on Monday offered an explanation for why top-ranked tennis player Jannik Sinner received a much shorter doping ban than the six-year suspension it handed to a Spanish figure skater in a similar doping case.

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