Former doubles world No.1 Paul McNamee has stated that Sinner's doping case is “sending shockwaves” through the tennis world. On Saturday, it was announced that the World Anti-Doping Agency (WADA) is in the process of appealing the International Tennis Integrity Agency's (ITIA) decision regarding the Italian player's case.
The current world No. 1 was declared to have “no fault or negligence” after two positive tests for clostebol during Indian Wells back in March. The news was made public almost six months after the positive test, and it only came to light once Sinner’s appeal determined his innocence.
Sinner was reportedly contaminated accidentally after being treated by physiotherapist Giacomo Naldi, who used a prohibited spray on hand wounds. When treating Sinner with bare hands, minimal contamination occurred, which, according to the investigation, would not have affected the two-time Grand Slam champion's performance.
Following WADA’s announcement, Paul McNamee, a five-time doubles Grand Slam champion, was among the first to react on X (formerly Twitter), saying: “Gee that’s sending shockwaves through tennis that WADA are appealing the ITIA decision to the Court of Arbitration of Sport in the Jannik Sinner case… that’s a very big call and I wasn’t expecting that.”
In WADA’s statement on 26th September, they aim to secure a suspension of between one and two years for Sinner: “It is WADA’s view that the finding of ‘no fault or negligence’ was not correct under the applicable rules. WADA is seeking a period of ineligibility of between one and two years. WADA is not seeking a disqualification of any results, save that which has already been imposed by the tribunal of first instance."
“As this matter is now pending before CAS, WADA will make no further comment at this time.”
No confirmation date for the final decision has been set. Meanwhile, Sinner is competing at the China Open, where he has already secured victories over Nicolas Jarry and Roman Safiulin, and is awaiting his quarterfinal match against Jiri Lehecka.

- One step by another step -- WTA continues to 'lose the plot'. Too many hi-tech microphones being installed at most venues!!! Remove them (especially those along the hallways, sidewalks, and pathways throughout the venues. Not to mention (most of all) remove the mic's from the Players/Coaches Box.

- Don't you just love this young lady!? We fans often expect athletes to be supermen and superwomen, often forgetting that they WILL GET TIRED! I love Alex's perspective. Tiredness for an athlete should never be viewed as a negative, especially if you are healthy, taking care of your body and mental health and putting in the work. What a mature perspective. Good for you, Alex!Rapunzel05-11-2026
- Jess is absolutely correct! But the disrespect is a trait I have noticed in most of the Russian players. Mirra is good but very immature and lacks humility. Conceivable needs to get a handle on that!Rapunzel05-11-2026
- Having spent weeks and weeks through the years on tour, I can say with confidence that Conchita was (is) one of the very few who realize the surprising level of maturity (and sometimes lack of) which Mirra seems to have developed in such a demanding adult world of Pro-Tennis. While at the same time reminding herself (Conchita, that is) that Mirra is still young and developing mentally and physically. The general public may forget at times, or not at all realize, these modern era young athletes do not have a 'normal' Youth. It's a major sacrifice, among countless sacrifices, these athletes must make. People who blow-off that fact are ignorant and unfair when they blurt out, "They choose fame so they have to put up with the intrusions on their lives". No, they do not.mandoist05-11-2026
- Okay... someone with a camera was EAVESDROPPING on a private conversation. Shouldn't that be the point of discussion here? Regardless of the sensationalist crap by media, Pegula (and anyone) has a right to an opinion. There used to be an expectation that private conversations were respected, regardless of 'stardom' and whatever other defensive excuses media tries to shove in our faces. Boo-hoo if feelings are hurt. BTW: Having been employed at various tourney venues, etc., I can't tell you how nasty and offensive players can be when discussing their opponents and colleagues... in "private". Well, I could, but won't. I also challenge anyone to deny what Jessica said is false.mandoist05-11-2026
