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.

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?"

I went down the rabbit hole and found this, a Wimbledon final won by default. The great Weller Evans recalled the 1969 U.S. Open between Rod Laver and Tony Roche. Owing to rain, the match was played on a Tuesday and even then, they used a helicopter to dry the grass court. Laver won (consecrating his second Grand Slam) while wearing track spikes.

Jannik Sinner, who tested positive for the steroid clostebol at last year’s Indian Wells tournament, will not miss any Grand Slams.

Jannik Sinner had obstacles thrown in his path during his suspension from tennis, but he has found a solution.
