LONDON — Dayana Yastremska’s latest appeal in her doping case was dismissed by the Court of Arbitration for Sport, meaning she is still ineligible to return to competition.
Yastremska traveled to Australia after being provisionally banned, hoping to be allowed to play in the Australian Open, which is scheduled to start Monday.
The 20-year-old Ukrainian 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.
She asked that her provisional penalty be set aside, and that was denied. Then she appealed that ruling to the Court of Arbitration for Sport, which rejected that request.
Yastremska, who has denied using performance enhancers or prohibited substances, now must await the final resolution of her case.
Yastremska has won three WTA singles titles. She reached a career-high ranking of No. 21 a year ago and is now No. 29. Her best showing at a Grand Slam tournament was reaching the fourth round at Wimbledon in her main-draw debut there in 2019.
ASTANA, Kazakhstan — Carlos Alcaraz’s first match as the No. 1-ranked player ended with a straight-set loss to David Goffin at the Astana Open.
The 19-year-old Spaniard lost 7-5, 6-3 in his first tour match since winning the U.S. Open and capturing the No. 1 ranking.
“David was playing really, really well. To come back to competition is never easy,” Alcaraz said. “It’s really tough for me, for my confidence.”
Alcaraz came from 5-2 down to level the first set at 5-5, only to be broken again by his Belgian opponent.
“When you play against the World No. 1 on a big stage, big crowd, the fire inside gives you so much power to play your best tennis because you don’t have any choice,” Goffin said. “You have to fight and give your best and that was the case today.”
Second-seeded Daniil Medvedev and No. 3-seeded Stefanos Tsitsipas both avoided similar upsets. Medvedev beat Albert Ramos-Vinolas of Spain 6-3, 6-1 and Tsitsipas ousted Kazakhstan’s Mikhail Kukushkin 6-3. 6-4.
OSTRAVA, Czech Republic — Fifth-seeded Daria Kasatkina defeated 2021 U.S. Open champion Emma Raducanu 7-5, 6-4 to advance to the second round of the Agel Open.

Sixth-seeded Belinda Bencic of Switzerland rallied to eliminate former top-five player Eugenie Bouchard of Canada 6-7 (7), 6-1, while Aliaksandra Sasnovich upset eighth-seeded Jelena Ostapenko 6-2, 6-2.
American qualifiers Alycia Parks and Catherine McNally both advanced. Parks upset Czech Karolina Pliskova 6-0, 7-6 (3) and McNally eased past Anna Blinkova 6-1, 6-2 at the indoor hardcourt event in the Czech eastern city of Ostrava.
