ZHUHAI, China — Andy Murray’s singles comeback hit another roadblock as he lost 4-6, 6-2, 6-4 to Alex de Minaur of Australia in the second round of the Zhuhai Championships on Thursday.
Murray won his first tour-level match since having hip surgery in January when he beat Tennys Sandgren on Tuesday but couldn’t follow that up despite winning the first set, as he only converted two of his nine break points.
Top-seeded Stefanos Tsitsipas also exited the tournament as he was forced to retire before the third set against Adrian Mannarino of France. He had called for a trainer twice during the match.
Andreas Seppi of Italy advanced after saving five match points in the deciding tiebreaker before beating local favorite Zhang Zhizhen 7-6 (4), 4-6, 7-6 (8). Also, Croatia’s Borna Coric, who beat Wu Di of China 6-3, 6-3.
In another marathon match at the Chengdu Open, unseeded Belarusian Egor Gerasimov upset top-seeded John Isner 6-7 (11), 7-6 (5), 7-6 (4) to reach the quarterfinals.
Gerasimov will face Denis Shapovalov of Canada, who dispatched America’s Bradley Klahn 3-6, 6-3, 7-6 (3).
In another upset, Portugal’s Joao Sousa ousted second-seeded Felix Auger Aliassime of Canada 6-4, 6-7 (5), 6-4. He will play Lloyd Harris, who beat Serbia’s Dujan Lajovic 6-3, 6-3.
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.
