The 20-year-old Ukrainian Dayana Yastremska has failed the doping test following the urine semple provided on November 24! The semple was sent to the World Anti-Doping Agency ("WADA") accredited laboratory in Montreal for analysis and contained mesterolone metabolite.
Mesterolone is a Non-Specified prohibited substance, carrying a mandatory provisional suspension. Dayana was suspended on January 7, and has the right to apply to the Chair of the Independent Tribunal convened to hear her case.
Dayana is currently ranked 29th, finishing the previous season with four straight losses and hoping for a fresh start in 2021. The Ukrainian played in the Adelaide final at the beginning of the season and didn't repeat that results in the rest of the year, parting ways with Sascha Bajin and searching for a new coach.
The young gun won two titles in 2019 and wrapped up the season just outside the top-20 after producing aggressive and bold tennis. After losing form in the closing stages of 2020, the Ukrainian went to Dubai for pre-season practice and caught the coronavirus.
Dayana stayed away from the court for two weeks, returning to it before this big news came out today. The youngster said she is astonished and shocked, sharing a statement with her fans and denying she did anything wrong.
Dayana Yastremska tested positive for mesterolone metabolite in November.
"Dear all, A few days ago, I have received a notice from the ITF that I was tested positive for mesterolone metabolite on November 24, 2020.
I firmly state that I have never used any performance enhancing drugs or any prohibited substances. I am astonished and under shock, particularly given that two weeks prior to this test — on November 9 2020 —I tested negative at the WTA event in Linz.
After this last tournament of the year, I stopped practicing to rest prior to the start of the new season. Only a very low concentration of mesterolone metabolite was detected in my urine. Given that low concentration and given my negative test two weeks earlier, I have received scientific advice that the result is consistent with some form of contamination event.
Besides, I have been informed that this substance is meant for use as medication by men and that women are advised not to use it due to the adverse effects it causes. Due to the confidentiality of the proceedings, you will understand that I am not able to share any further information at this stage.
However, I am currently working with my team and you can be assured that I am resolutely determined to do everything to clear my name," Dayana Yastremska stated.
