In a dramatic and highly charged aftermath to the United Cup quarterfinal clash between Poland and Switzerland, Swiss tennis star Belinda Bencic unleashed a furious post-match outburst, publicly accusing world No. 1 Iga Świątek of using performance-enhancing drugs to secure her straight-sets victory.
Bencic, who fell 6-3, 6-4 to the dominant Świątek, waited until the on-court interview before letting her emotions boil over. With microphones still hot and cameras rolling, the 28-year-old Swiss player pointed directly at her opponent and declared: “She cheated! She used doping before the match.
In the past she was banned for that – it’s no surprise she used it again to compete. It’s really shameful that someone like her is in the world top.”
The accusation, broadcast live on international television, sent shockwaves through the tennis world.
Bencic’s reference to a past “ban” appeared to allude to a 2022 incident when Świątek tested positive for a banned substance (trimetazidine) but was quickly cleared by the ITIA after proving it was a contamination from a heart medication taken by her mother.
The claim instantly reignited old rumors and divided fans, with many calling Bencic’s outburst “desperate” while others demanded an immediate investigation.

Social media erupted within seconds. Hashtags #DopingŚwiątek and #BencicAccuses trended globally. Polish supporters rallied fiercely behind their star, while some neutral observers expressed concern over the potential damage to Świątek’s reputation.
But Iga Świątek, known for her composure under pressure both on and off the court, refused to let the accusation stand unanswered.
Exactly five minutes after Bencic’s interview concluded, Świątek posted a single tweet that would change the course of the story:
“I have never doped. I never will. Test me today, tomorrow, every day – I have nothing to hide.”
The 15-word statement was simple, direct, and devastating in its confidence. Within minutes, it had been retweeted over 2 million times and liked more than 4 million. The tennis community exploded.
Players, coaches, and fans from every corner of the globe voiced their support for Świątek, praising her immediate transparency and courage.
The WTA and International Tennis Integrity Agency (ITIA) moved with unprecedented speed. Within hours of the tweet, the governing bodies announced an emergency, voluntary, out-of-competition drug test on Świątek – conducted right there in Perth under independent supervision.
The sample was rushed to a WADA-accredited laboratory in Sydney for expedited analysis.
The result came back less than 24 hours later – and it left everyone stunned.

Świątek tested completely negative for all prohibited substances. No traces of any banned performance-enhancers were found. The ITIA issued a formal statement confirming the results and reiterating that Świątek’s 2022 case had been resolved with a finding of no fault or negligence.
The clean test not only cleared Świątek’s name but turned the spotlight back onto Bencic’s explosive accusation. Many now view the Swiss player’s claim as reckless and potentially defamatory. Legal experts suggest Bencic could face significant backlash, including possible fines, suspension points, or even civil action from Świątek’s team.
In a brief follow-up statement, Świątek addressed the situation with her trademark calm:
“I respect Belinda as a competitor and understand the frustration of losing. But accusations like this hurt everyone in our sport. I will continue to compete clean, play hard, and let my tennis speak for itself.”
Bencic, for her part, has not retracted her comments or issued an apology as of this writing. Her team released a short note saying she “stands by her emotions in the heat of the moment” but declined further comment pending legal consultation.

The incident has reignited fierce debate about mental health in high-stakes tennis, the dangers of post-match accusations, and the importance of due process in doping allegations. Many players have rallied around Świątek, with world No. 2 Aryna Sabalenka posting: “Iga is the cleanest athlete I know.
This is disgusting.” Even retired legends like Roger Federer and Serena Williams expressed support via social media.
For Świątek, the controversy – though painful – may ultimately strengthen her legacy. The swift, transparent test and the overwhelming public support have transformed what could have been a damaging scandal into a powerful demonstration of integrity.
Poland advanced to the semifinals, while Switzerland’s campaign ended. But the real winner of the day may be the truth itself.
In a sport often plagued by whispers and suspicion, Iga Świątek proved once again why she sits alone at the top: not through shortcuts, but through relentless, clean excellence.
