According to the Associated Press on Thursday, Dayana Yastremska of Odesa, Ukraine has tested positive for the banned substance of mesterolone metabolite. The drug which is used to boost testosterone, is an anabolic agent used in male infertility treatment.
Currently ranked 29th in the world, it will be interesting to see how long Yastremska will be suspended for. At this time she has been “provisionally suspended.” Do not be surprised if Yastremska takes her case to the Court of Arbitration for Sport.
Yastremska is the second high-profile Ukrainian athlete to test positive for mesterolone metabolites. Thirty-year-old ultimate fighter Aleksander Doskalchuk tested positive for the substance in September, and got a 14-month suspension by the United States Anti-Doping Agency. He is not eligible to return to ultimate fighting until August 6.
Despite her current ranking of 29th in the world, and a career-high ranking of 21st in the world, Yastremska has not had a great deal of success in grand slam tournaments. The highest she has reached has been the fourth round of Wimbledon in 2019.
Yastremska is a three-time champion on the WTA Tour. She previously beat Qiang Wang 6-2, 6-1 in the final of the 2018 Hong Kong Open; Ajla Tomljanovic of Australia 6-2, 2-6, 7-6 in the final of the 2019 Hua Hin Championship in Thailand; and Caroline Garcia of France 6-4, 5-7, 7-6 in the final of Strasbourg in France in 2019.
Since September, Yastremska has made tennis headlines on multiple occasions. She first split with her coach, Sascha Bajin of Germany, and then she tested positive for coronavirus in December.
