Serena Williams' ex-coach pinpoints key difference between Iga Swiatek and Simona Halep's doping cases

Serena Williams' former coach, Rennae Stubbs, recently highlighted the significant differences between the doping cases of Iga Swiatek and Simona Halep. Halep tested positive for the banned substance Roxadustat, while Swiatek tested positive for trimetazidine.

In 2023, Halep received a four-year ban from the International Tennis Integrity Agency (ITIA) for violating anti-doping regulations and testing positive for Roxadustat during the 2022 US Open. She appealed her suspension to the Court of Arbitration for Sport (CAS), claiming that contaminated nutritional supplements were the cause. The CAS reduced her suspension to nine months following an investigation.

On the other hand, Swiatek tested positive for trimetazidine due to contamination from a regulated non-prescription melatonin medication this year in August. She was temporarily suspended in September but after appealing the suspension, she was found to have 'No Significant Fault or Negligence,' however, she still received a one-month suspension.

During a recent episode of her podcast, 'The Rennae Stubbs Tennis Podcast,' Stubbs delved into the doping controversies surrounding Iga Swiatek and Simona Halep and pointed out the distinctions between their cases.

Stubbs noted that a key argument arising from the doping cases of Swiatek, Jannik Sinner, and Halep is the perception that Swiatek and Sinner, the latter of whom tested positive for the prohibited substance Clostebol in March 2024, received "preferential treatment" due to their world rankings.

“I think that there’s so many arguments going back and forth, one of them is, ‘Oh, it's preferential treatment just like with Jannik Sinner. He’s getting preferential treatment as the No.1 player in the world and Iga Swiatek is getting preferential treatment because of her ranking.’ And look, some of it might be true in the fact that they both have money, they both have lawyers and they both have a team to be able to get behind them, to get to the bottom of it really quickly as opposed to other things,” Stubbs said [10:46].

The 53-year-old stated that both Swiatek and Sinner were able to swiftly address their cases due to their financial resources, legal teams, and the support of their respective teams.

Rennae Stubbs pointed out that the main difference between Halep and Swiatek's case is that while the Romanian took a considerable amount of time to prove that her nutritional supplements were contaminated, Swiatek swiftly proved her innocence.

“I think the difference with Simona Halep, same thing: plenty of money, plenty of resources. I think the issue and the difference is that it took her a long time to figure out where the contamination was coming from. That was part of the problem for her,” she added [11:09].

Stubbs further explained that in addition to testing positive for a significant amount of Roxadustat, which led to a lengthy suspension for Halep, the ITIA also discovered discrepancies in her biological passport which played a role in her long suspension.

“Then also she had quite a large amount of whatever the stuff was, Roxadustat, that was in her system. Then there was a discrepancy with the passport or biological passport et cetera, et cetera. I think that got squashed, I think at some point,” Rennae Stubbs said [11:21].

Former German player Andrea Petkovic, who was also present during the podcast, added that Simona Halep's case was 'chaos,' which contributed to the prolonged resolution process.

“It was a hot mess, it was chaos and that’s why it wasn’t easily resolved and that’s why it took so long for her. I understand that she feels hurt and then she feels maltreated in a way. I think these cases have taught us nothing but to look at each and every single one individual independently,” Andrea Petkovic said [11:40].

What Simona Halep & Iga Swiatek have said about their doping scandal

While speaking with 'We Are Tennis' earlier this year, Simona Halep shared that the most challenging aspect of her doping suspension was not being able to attend a tennis match.

Halep said that the entire doping debacle made her realize that life is "beautiful" but also "hard."

"I could not go watch a tennis match. This was the most difficult thing. But after this experience that I went through, I'm a little bit scared, because life, it's beautiful, but it's also hard sometimes. You never know what to expect," Halep said.

Meanwhile, Iga Swiatek took to social media to address her one-month suspension following the positive doping test. Swiatek expressed that the incident had cast doubt on everything that she had worked tirelessly for throughout her life.

“The only positive doping test in my career put everything I’ve worked so hard for my entire life into question. Now everything has been carefully explained, and with a clean slate I can go back to what I love most. I know I will be stronger than ever. I’m just relieved it’s over," Iga Swiatek said.

Swiatek has served three weeks of her suspended sentence and has one week left to serve, which might force her to miss the 2025 United Cup. She is expected to begin her 2025 season at the Australian Open, which is scheduled after the United Cup.
