Ukrainian tennis player Yastremska's doping appeal denied

LONDON (AP) — Professional tennis player Dayana Yastremska's latest appeal of her provisional doping suspension was denied Tuesday, keeping her sidelined. The 20-year-old Ukrainian, who has been ranked as high as No. 21, originally was suspended in January for failing an out-of-competition drug test. She tested positive for mesterolone metabolite, a prohibited substance that can be used to boost testosterone.
