WADA general counsel Ross Wenzel said: "WADA went back and looked at every single one of Mr Sinner's samples for the 12 months before the two positives in March of last year to see whether there was any even indication, albeit not meeting the identification criteria, but any suspicious indication of this substance in any of those samples.
Mr Wenzel said: "This was, if you like, almost the paradigm case for agreeing a resolution, because the minimum sanction [a one-year ban] would, in our view, and I think many would agree with this, have been unfair given the specific facts of this case.

So I think whatever people say and think about this case, it is not a doping case or a cheating case.".
