LONDON — The International Tennis Federation 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.
Yastremska drew a provisional suspension by the ITF on Jan. 7. She had tested positive for mesterolone metabolite, a prohibited substance that can be used to boost testosterone.
In a statement on her Twitter feed then, Yastremska said she was “astonished and under shock.”
“I firmly state that I have never used any performance enhancing drugs or any prohibited substances,” she said.
She said she passed a drug test at her most recent tournament, in Austria on Nov. 9.
Yastremska has won three WTA singles titles. She reached a career-high ranking of No. 21 a year ago. Her best showing at a Grand Slam tournament was reaching the fourth round at Wimbledon in her main-draw debut there in 2019.
“You can be assured that I am resolutely determined to do everything to clear my name,” Yastremska said.
The 2021 tennis season started this month, including a WTA tournament in Abu Dhabi, United Arab Emirates. The year’s first major championship, the Australian Open, begins Feb. 8 in Melbourne.
Yastremska had traveled to Melbourne aboard one of the Tennis Australia charter flights and was in quarantine pending the result of the ITF hearing.
OSTRAVA, Czech Republic — American qualifier Alycia Parks is having quite the breakthrough tournament in Ostrava.
The 21-year-old Parks earned her first win against a top-10 ranked opponent by beating fourth-seeded Maria Sakkari 5-7, 7-5, 7-5 at the Agel Open on Thursday to reach her first WTA Tour quarterfinal.
The 144th-ranked Parks ousted former No. 1 Karolina Pliskova in the opening round – her first win against a top-20 opponent – and showed off her power by hitting 59 winners against Sakkari, compared to just nine for her opponent.
“I came out here not expecting anything, just playing my game, and it got me through the match,” Parks said.
Parks will next face former French Open champion Barbora Krejcikova, who advanced via walkover when Belinda Bencic withdrew with a left foot injury.
Caty McNally, another American qualifier who is playing doubles with Parks in Ostrava, also reached the last eight by beating wild-card entry Karolina Muchova 6-1, 3-6, 6-1. McNally is also into her first WTA quarterfinal and will face top-ranked Iga Swiatek, who advanced Wednesday.
ASTANA, Kazakhstan — Add Botic van de Zandschulp to the long list of players to have been schooled by Novak Djokovic.
Djokovic eased past Van de Zandschulp 6-3, 6-1 on Thursday in his first career meeting with the 27-year-old Dutchman to reach the quarterfinals of the Astana Open.
Van de Zandschulp earned one break point in each set but couldn’t seriously threaten Djokovic, who is looking for a second straight indoor hardcourt title after winning in Tel Aviv last week.
“(In the) second set I think I started to read his serve better and just started swinging through the court more,” Djokovic said. “Botic is a quality tennis player. When he has time, he can hurt you, so I tried to take away that time from him and I’m very pleased with the way I played, particularly in the second.”
Djokovic will next face Karen Khachanov, who rallied to beat Marin Cilic 2-6, 6-3, 6-3. If the 21-time Grand Slam champion gets past that one, he could come up against fellow former No. 1 Daniil Medvedev. The second-seeded Russian beat Emil Ruusuvuori of Finland 6-3, 6-2 to move one match away from a potential rematch of last year’s U.S. Open final, when Medvedev beat Djokovic to deny his attempt at a calendar-year Grand Slam.
Medvedev will first have to beat Roberto Bautista Agut, who advanced Wednesday.
