Ukraine's world number 29 Yastremska was provisionally suspended on Jan. 7 after WADA found a banned substance in an out-of-competition urine sample. The 20-year-old provided the sample in November and a WADA lab in Montreal found the presence of mesterolone metabolite, an anabolic agent on its Prohibited List. "An application by Dayana Yastremska to lift the provisional suspension imposed on her on Jan. 7 under Article 8.3.1(c) of the 2020 Tennis Anti-Doping Programme has been denied by the Chair of the Independent Tribunal convened to hear her case," the ITF said in a statement on Saturday.
The International Tennis Federation on Saturday denied a bid by 29th-ranked Dayana Yastremska to lift a suspension for failing an out-of-competition doping test. The ruling can be appealed to the Court of Arbitration for Sport by the 20-year-old Ukrainian. Players at Grand Slam tournaments and events sanctioned by the ITF, ATP and WTA are tested for substances prohibited by the World Anti-Doping Agency.
Former top-25 player Filippo Volandri was named Italy's Davis Cup captain on Saturday, ending Corrado Barazzutti's 20-year run in charge. Barazzutti had also previously been Italy's Fed Cup captain, a role he ceded to Tathiana Garbin in 2016 after coaching the women's team to four titles. Barazzutti played on Italy's team that won the Davis Cup in 1976.
