The case of the world No. 1 in men's tennis is at the center of anti-doping protocols and reforms that could redefine its parameters.

The timing means the 23-year-old Italian won't miss any Grand Slam tournaments. The French Open, the season's next major, starts May 25.

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

As everyone knows by now, Jannik Sinner has reached an agreement with WADA that provides for a three-month suspension for the world number 1. On April 16 and 17, the trial before the CAS in Lausanne was scheduled, in which the Italian ace could have been acquitted or suspended from one to two years.

For too long it seems WADA has cast out athletes, particularly those with little access to top legal teams like that on Sinner’s side

Jannik Sinner received a 3-month ban after testing positive for a banned substance, with the Italian initially refusing to accept he would face a suspension.

Sinner asked: "Why would we do that if the first independent tribunal found it was no ban at all, why would I accept three months now?"
