AP – Top 30 tennis pro Dayana Yastremska was provisionally suspended for failing an out-of-competition doping test, the International Tennis Federation (ITF) announced recently.
The ITF said Yastremska, a 20-year-old Ukrainian, tested positive for mesterolone metabolite, a prohibited substance that can be used to boost testosterone.
In a statement posted on her Twitter feed, the 29th-ranked Yastremska said she is “astonished and under shock”.
“I firmly state that I have never used any performance enhancing drugs or any prohibited substances,” Yastremska said. A punishment would not be decided until after a full hearing. The ITF said Yastremska has a right to appeal the provisional ban but has not yet done so.
She reached a career-high ranking of number 21 in January 2020, and her best showing at a Grand Slam tournament was reaching the fourth round at Wimbledon in her main-draw debut there in 2019.
Yastremska has won three WTA singles titles. She said she passed a drug test at her most recent tournament, an event in Austria on November 9, 2020.
