Won't appeal in Iga Swiatek doping case, says WADA

Iga Swiatek ’s one-month suspension for failing a drug test will not be appealed by the World Anti-Doping Agency ( WADA ), which deemed her explanation “plausible,” according to a statement released on Monday.

The announcement came shortly after Swiatek’s commanding 6-0, 6-1 victory over Eva Lys, which secured her a spot in the Australian Open quarterfinals.

Swiatek, a five-time Grand Slam champion and former world number one, tested positive for trimetazidine (TMZ), a banned heart medication, during an out-of-competition test in August.

However, the International Tennis Integrity Agency (ITIA) accepted her explanation that the positive result was caused by contamination from melatonin, a non-prescription medication she was taking to combat jet lag and sleep issues.

The ITIA determined her fault was “at the lowest end of the range for no significant fault or negligence,” and WADA, after consulting external legal counsel, agreed there were no scientific or legal grounds to challenge the decision.

“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 said in its statement.

Swiatek had already served her suspension, missing three tournaments in October, and completed the ban during tennis’s offseason. The ITIA publicly disclosed the resolution of her case in November.

Reflecting on the suspension during a press conference at the Australian Open, Swiatek described the period as one of the most challenging in her life. "For sure, it wasn’t easy; it was probably, like, the worst time in my life," she admitted.

Initially, Swiatek and her team chose not to disclose the suspension publicly, citing "personal reasons" for her absence.

“It got pretty awkward. We thought the suspension would be lifted quickly, and from the beginning, it was obvious that something was contaminated because the level of this substance in my urine was so low that it had to be contamination,” she explained.

In contrast to Swiatek’s case, WADA has appealed the exoneration of current men’s world number one Jannik Sinner . Sinner was cleared by the ITIA after two positive tests for an anabolic steroid in March were deemed to involve no negligence. WADA’s appeal will be heard by the Court of Arbitration for Sport (CAS) in April.

Swiatek's quick return to form at the Australian Open suggests she has moved past the controversy and is focused on competing at the highest level once again.
