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.
STUTTGART, Germany — Matteo Berrettini beat Canadian teenager Felix Auger-Aliassime 6-4, 7-6 (11) to win the Stuttgart Open and his third tour-level title on Sunday.
The Italian saved five set points in a second-set tiebreaker and clinched his first title on grass. His other titles came at Budapest in April, and Gstaad, Switzerland, last year.
The 18-year-old Auger-Aliassime previously reached championship matches in Rio de Janeiro in February and the Lyon Open in May – both on clay.
Berrettini won all 50 of his service games during the week in Stuttgart. He did not face a break point against Auger-Aliassime.
Auger-Aliassime progressed to the final in his first professional grass tournament without playing Saturday as compatriot Milos Raonic withdrew ahead of their semifinal due to back problems.
NOTTINGHAM, England — Former champion Donna Vekic finally got to play on grass at the Nottingham Open on Friday but had to overcome multiple rain delays and another switch indoors before reaching the semifinals.
The second-seeded Vekic defeated Kristina Mladenovic 7-5, 6-4 in a match played on two surfaces as rain again played havoc with the schedule.
The opening two days were completely washed out before organizers decided to switch the first and second rounds indoors as rain fell for four consecutive days.
Vekic, who won the tournament in 2017, will play Germany’s Tatjana Maria in her third straight semifinal in Nottingham. Maria earlier defeated Ajla Tomljanovic 6-3, 7-6 (7) in the only match completed on grass so far at the tournament.
Also Friday, American Jennifer Brady defeated fourth-seeded Maria Sakkari of Greece 7-5, 6-3 to set up a semifinal against top-seeded Caroline Garcia.
Garcia rallied to beat Romanian qualifier Elena-Gabriela Ruse 4-6, 7-6, 6-1 in the last quarterfinal.
