STUTTGART, Germany – U.S. Open champion Emma Raducanu defeated Germany’s Tamara Korpatsch 6-0, 2-6, 6-1 at the Stuttgart Open to set up a quarterfinal match against top-ranked Iga Swiatek.
It will be the 19-year-old Raducanu’s first match against a top 10 opponent.
Raducanu, who won at Flushing Meadows as a 150th-ranked qualifier last year, could break into the top 10 herself if she wins the Stuttgart title in what is her first professional tournament on clay. She’s currently ranked 12th.
Earlier, second-seeded Paula Badosa defeated Kazakhstan’s Elena Rybakina 6-2, 4-6, 7-6 (4) and will face Ons Jabeur in the quarterfinals. Jabeur defeated Daria Kasatkina 6-3, 6-3.
Third-seeded Aryna Sabalenka defeated Canada’s Bianca Andreescu 6-1, 3-6, 6-2 and will face Anett Kontaveit or Ekaterina Alexandrova.
Fouth-seeded Maria Sakkari retired against Laura Siegemund as the German was leading 6-4, 3-1. Siegemund next plays Russian player Liudmila Samsonova, who defeated Karolina Pliskova 6-4, 6-4.
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.
