Will Jannik Sinner’s positive steroid test impact his US Open odds? 

The No. 1-ranked tennis player in the world has tested positive for an anabolic steroid.

Italian Jannik Sinner — the second-best favorite to win the US Open, which starts later this month — tested positive twice for clostebol, a steroid that has resulted in punitive actions for other athletes such as Padres superstar Fernando Tatis Jr., former Marlins shortstop Dee Gordon and former Phillies infielder Freddy Galvis.

The positive tests occurred in March during the Indian Wells Tournament. Sinner was suspended, but was permitted to continue playing while awaiting an appeal.

In the end, the International Tennis Integrity Agency agreed with Sinner's assessment that a support team member passed the anabolic steroid to him through his skin from "daily massages and sports therapy." The support team member had been applying an over-the-counter spray that contained clostebol on himself to treat a small wound, the ITIA said in its findings.

The ITIA said in its ruling that Sinner would not face a suspension due to his claims, which were backed by medical professionals. He's required to forfeit his prize money winnings at Indian Wells ($325,000) and the points accumulated from that tournament, however.

Sinner's odds to win the US Open remain unchanged since the announcement on Tuesday morning. At FanDuel, he's still +260, just behind Carlos Alcaraz at +160 and reigning champion Novak Djokovic at +270.
