“It doesn’t make sense”: Jessica Pegula compares Vondrousova suspension with Sinner and Swiatek doping cases

Jessica Pegula was in a whole heap of battles in the Asian swing

Jessica Pegula has questioned the consistency of anti-doping rulings in tennis after Marketa Vondrousová’s four-year suspension sparked renewed debate across the sport, drawing direct comparisons with previous cases involving Jannik Sinner and Iga Swiatek.

Vondrousova’s case stems from an out-of-competition test attempt at her home in December 2025, when she did not submit a sample after being notified by a doping control officer. The 2023 Wimbledon champion later said “months of physical and mental stress” influenced her reaction, while also raising concerns about privacy and safety during testing procedures.

Players are required to provide a daily one-hour whereabouts window for out-of-competition testing. Vondrousova has insisted she “never doped” and is now expected to consider an appeal to the Court of Arbitration for Sport, while facing a suspension that could keep her out of competition until 2030.

The case has intensified scrutiny due to its perceived severity compared to other recent rulings involving top players, particularly Sinner and Swiatek, whose sanctions were significantly shorter and based on different findings of fault and contamination.

Pegula was explicit in her criticism of the perceived inconsistency between cases, arguing that from a “common sense” perspective, the outcomes are difficult to reconcile. She acknowledged she does not have full access to the details but questioned the overall proportionality of the sanction.

"It's just really unfortunate. I feel like for Marketa, I don't know the ins and outs of exactly what happened, it seems like there's a lot of 'he said, she said' kind of things going on right now," Pegula said to AFP.

She then focused on the scale of the punishment, stating that a four-year ban risks ending a player’s career over what could be a misunderstanding, especially when compared with other anti-doping cases in recent seasons.

"But I just think for something like that, for four years, you're ruining someone's career over something that could have really just been a complete misunderstanding,” the world No. 5 added. "I just don't think that's fair. I think the sentencing is so harsh."

Sinner and Swiatek cases central to Pegula’s criticism

The debate intensified as Pegula directly referenced the contrasting outcomes in cases involving Jannik Sinner and Iga Swiatek, both of whom served significantly shorter suspensions under different circumstances.

Sinner was suspended for three months after testing positive for the anabolic steroid clostebol in 2024. The World Anti-Doping Agency (WADA) accepted that the contamination was inadvertent and linked to a massage cream used by his physiotherapist. During an ongoing appeals process, the Italian ultimately agreed to a short suspension to close the case.

Swiatek received a one-month ban in late 2024 after testing positive for trimetazidine. The International Tennis Integrity Agency determined the result came from a contaminated over-the-counter melatonin supplement manufactured in Poland. She was found to have “No Significant Fault or Negligence,” resulting in a reduced sanction.

Pegula pointed to these outcomes when questioning how similar regulatory frameworks can lead to such different punishments depending on context and interpretation.

"I don't quite understand the difference between that and then obviously what happened with Sinner and Iga," Pegula said. "They justified what the rules were and why it was the way it was."

She concluded that, while punishment is necessary when testing protocols are breached, the system lacks clarity from a player’s perspective.

"I don't think it makes sense to a person that's just looking at it common sense-wise,” the 31-year-old American added. “But I understand there should be some sort of punishment, because I know she's refused to take a test, and that's not good either."
