Why wasn't Jannik Sinner suspended after two positive steroid tests? What do other players think?

No. 1-ranked men's tennis player Jannik Sinner will be playing in the U.S. Open — which begins in New York next week — even though word just emerged that he tested positive twice in March for a banned anabolic steroid.

It's a case that no one knew about until Tuesday and one that has drawn all sorts of questions — and, in some instances, criticism — from other players who wonder whether there was a double standard at play because of Sinner's success, are confused about why this was all kept under wraps, and want to know why Sinner was allowed to keep competing before there was a resolution.

“I will now put this challenging and deeply unfortunate period behind me,” Sinner said in a statement posted on social media. “I will continue to do everything I can to ensure I continue to comply with the (sport's) anti-doping (program) and I have a team around me that are meticulous in their own compliance.”

Not everyone is completely ready to just move forward. And it will be interesting to see how much scrutiny Sinner receives — from other athletes, from spectators, from the media — during the year's last Grand Slam tournament, where he will be the top-seeded man.
