Building trust crucial, says tennis's anti-doping agency

LONDON : Improving trust in anti-doping rules is a priority for the International Tennis Integrity Agency after several high-profile cases last year raised doubts over its processes, CEO Karen Moorhouse said in the ITIA's annual review.

Men's world number one Jannik Sinner accepted an immediate three-month ban in February after reaching an agreement with the World Anti-Doping Agency (WADA) which appealed against the decision of an independent tribunal to clear him of any wrongdoing after a positive doping test.

Poland's five-times Grand Slam champion Iga Swiatek accepted a one-month suspension in November having tested positive for banned substance trimetazidine (TMZ) which she said was the result of contamination of her sleep medication.

The speed with which Sinner and Swiatek's cases were dealt with, and the leniency shown, cast a spotlight on the anti-doping system after former world number one Simona Halep criticised officials for lengthy delays in her own case.

"(The Jannik Sinner) case has invariably raised further questions about the anti-doping process in tennis," Moorhouse said in the report published on Thursday. "We - alongside our funders - are determined to answer them, and drive deeper understanding of the work we do within the sport.

"The complexity of the system is one of the many reasons why it's important that we continue to work together with our members and tennis stakeholders to build trust."

Accusations of double standards were aimed at the ITIA while 24-times Grand Slam champion Novak Djokovic said there had been a lack of consistency and transparency in the cases while Australian Nick Kyrgios described the Swiatek and Sinner cases as "disgusting" for the sport.
