The World Anti-Doping Agency (Wada) has defended its handling of Jannik Sinner’s drugs ban, with a senior figure insisting the World No 1’s case was a “million miles away from doping”. It was announced on Saturday that Sinner had reached a settlement with Wada over a pair of positive drugs tests recorded in March last year that will see the three-time grand slam champion banned for three months. Sinner, 23, will return in time for his home tournament at the Italian Open in May and will be available to play in the next grand slam at the French Open later that month.
