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.

Although Jannik Sinner's doping case is now over, the feeling is that the agreement between the world number 1 and WADA will continue to be discussed for some time. The Italian ace - who risked suffering a suspension of 1 to 2 years for 'strict liability' - avoided going to trial before the CAS in Lausanne and accepted a three-month suspension.

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?"
