Unlike Jannik Sinner and Simona Halep before her, Iga Swiatek will not have to go to CAS for an appeal of her doping violation after WADA confirmed they will not appeal the ruling saying that the evidence presented is 'plausible' and there are 'no scientific grounds' to do so.
Sinner will have to go to CAS in April and could yet face a ban of up to two years. Halep initially had her suspension sit at four years but was down to nine months after appeal albeit her career has not returned to any rate of pre doping issues.
Swiatek tested positive for the substance trimetzidine (TMZ) which is used for jet lag and sleep. She bore no significant fault or negligence according to the finding but served a one month ban during the Asian hard court swing.
A decision criticised as Swiatek lost her World No.1 spot and didn't play initially as she said she was making changes to her team. That was true but also she served a suspension during this time. The news was confirmed after her rampant 6-0, 6-1 win over Eva Lys at the Australian Open.
Like Sinner, Swiatek as a figurehead of the sport has faced vehement criticism over the doping issue albeit mainly aimed at the authorities over her.
"WADA has conducted a full review of the case file related to the ITIA decision, which it received on 29 November. WADA’s scientific experts have confirmed that the specific contaminated melatonin scenario, as presented by the athlete and accepted by the ITIA, is plausible and that there would be no scientific grounds to challenge it at CAS."
"Further, WADA sought advice from external legal counsel, who considered that the athlete’s contamination explanation was well evidenced, that the ITIA decision was compliant with the World Anti-Doping Code, and that there was no reasonable basis to appeal it to the CAS."
🚨🇵🇱 WADA will NOT appeal Iga Swiatek's case:

- Can't help but suspect Vukov is back to his old self again. Thank you, WTA. Perhaps you can give them a "Battling Couple of the Year Award 2026" ??
mandoist08-11-2026 - Wtf? Why is there no reason? And what about the men's?Bel08-11-2026
- 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.mandoist06-11-2026
- Enough of her bullshit. Go marry someone.mandoist06-11-2026
- 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

- After a couple decades traveling to IIHF tourneys overseas... our family is done with it... and I will not be the only one!! Bad enough the NHL allows Ovachenko (a Putin Supporter and Campaigner) to live and play in the USA. Let's not forget the STATE SPONSORED RUSSIAN DOPING PROGRAMS still in effect today.mandoist31-10-2026
