Runner-up Paula Badosa survived the panic on her way to a 6-2, 5-7, 7-6 (7/5) win over US qualifier Elisabeth Mandlik on Wednesday at the WTA Hard Surface Tournament in San Jose , California.
After comfortably winning the first set with two service breaks, Spain’s Badosa lost an early break in her second match against her 240th-placed opponent, who is the daughter of four-time Grand Slam champion Hana Mandlikova.
She bounced back but broke again in Game 11 to give Mandlik a chance to hit the set and extend the match.
After a 4–3 break in the third match, Mandlik had two chances to serve for a set, but they traded service breaks in the last three games to send him to a tiebreak that saw world No. 4 Badoza win the last five. points to seal the win.
Badosa next faces the winner of Thursday night’s showdown between four-time Grand Slam champion Naomi Osaka and sixth-placed American Coco Gauff.
Japanese superstar Osaka is unseeded as she plays her first tournament since falling in the first round of the French Open where she struggled with a left Achilles tendon injury.
Gauff, runner-up at the French Open, is in sixth place.
Third-placed Tunisian star Ons Jabeur, who played his first game since finishing second at Wimbledon in history, pulled away late to beat American Madison Keys 7-5, 6-1.
Zhaber will face Veronika Kudermetova or Claire Liu in Friday’s quarter-finals.
Jabeur started well from the early break and took a 2-0 lead before Keys took a 5-3 lead.
Jabeur responded by winning 10 of the next 11 games.
“I’m grateful I played at night because it’s slower and helps me a bit in conditions,” said Jabeur. “I knew it would be a tough match for me. I was just trying to stay low and hit the ball as often as I could. Get her to play another ball and in the end I felt a lot better.”
American Amanda Anisimova defeated Czech Karolina Pliskova for the first time in five attempts and advanced to the quarterfinals.
Anisimova trailed with a set and a break en route to a 3-6, 7-5, 6-1 win.
