Sinner 'surprised' by World Anti-Doping Agency appeal

Jannik Sinner says he is "surprised" by the World Anti-Doping Agency's appeal against the decision to clear him of blame after he twice tested positive for a banned substance.

Wada said the August ruling by an independent tribunal to find the Italian world number one had no fault or negligence was "not correct under the applicable rules".

It has appealed to the Court of Arbitration for Sport (Cas) and said Sinner should be banned for "between one and two years".
