HUA HIN, Thailand — Garbine Muguruza rallied from a 4-0 deficit in the second set to beat Mona Barthel 6-3, 7-5 Wednesday in the second round of the Thailand Open.
The two-time Grand Slam champion said it was a “difficult match.”
“She had a lot of advantages but I’m happy that I kept fighting and ended up winning,” said Muguruza, who won the French Open in 2016 and Wimbledon a year later.
Muguruza will next face eighth-seeded Dayana Yastremska, who beat wild-card entry Peng Shuai 6-1, 6-4.
“In the first set, I felt really well on court but in the second set I felt a bit weak,” said Yastremska, an 18-year-old Ukrainian. “But I tried to keep myself under control and stayed focused like I did in the first set, which is the key for me to take the second set.”
Yastremska beat Muguruza last year in Luxembourg, winning 6-2, 6-3.
“She is young and has nothing to lose,” Muguruza said. “She is playing well right now. It will be a tough match.”
Also, fourth-seeded Saisai Zheng beat Irina-Camelia Begu 6-2, 6-4 and sixth-seeded Ajla Tomljanovic defeated Kateryn Kozlova 7-6 (0), 6-1.
NEW YORK (AP) Defending champions Naomi Osaka and Novak Djokovic are the No. 1 seeds for singles play in the U.S. Open.
Osaka, who beat Serena Williams in last year’s final for her first Grand Slam title, recently regained the top spot in the WTA rankings from Ash Barty. Barty is the No. 2 seed, followed by Karolina Pliskova, Wimbledon champion Simona Halep and Elina Svitolina.
Williams was given the No. 8 seed Wednesday by the U.S. Tennis Association. Madison Keys, the 2017 runner-up who just won the Western & Southern Open, rounds out the top 10 seeds.
Djokovic, bidding for his second straight major title, is followed by fellow past U.S. Open champions Rafael Nadal and Roger Federer. Dominic Thiem is No. 4 and surging Daniil Medvedev, who won the title outside Cincinnati last week in what was his third straight tournament reaching the final, is fifth.
The draw will be held Thursday and main-draw play begins Monday.

NEW YORK (AP) Wimbledon semifinalist Barbora Strycova was knocked out of the Bronx Open on Tuesday with a 3-6, 6-2, 6-1 loss to Bernarda Pera.
Strycova was the No. 3 seed and was playing her opening match in the new WTA tournament after receiving a first-round bye. But the 33-year-old Czech, the oldest player in the field, was handled easily by the American wild-card entrant over the final two sets on a hot afternoon after winning the first set.
Pera will play No. 5 Katerina Siniakova, who had rolled to a 6-0, 3-0 lead over Anastasia Potapova before the Russian qualifier retired.
The other quarterfinal matchup set up Tuesday will feature Camila Giorgi, who outlasted Andrea Petkovic 3-6, 7-5, 7-6 (3), against Alize Cornet, who was leading 7-6 (5), 4-0 when Zhu Lin had to retire with an injury.
