Fourth-seeded Veronika Kudermetova defeated fifth-seeded Beatriz Haddad Maia 6-7 (4), 7-6 (6), 6-1 to reach the semifinals of the Toray Pan Pacific Open on Friday.
The 25-year-old Russian, 13th in the world rankings, fired 11 aces and converted six of her 15 breakpoints against the Brazilian, who struggled with fatigue in her legs during the match at Ariake Tennis Forest Park in Tokyo.
After taking the tiebreaker in the second set with a cross-court backhand winner, Kudermetova traded breaks with Haddad Maia at the start of the deciding set.
Kudermetova then finally took the lead 2-1 by breaking Haddad Maia’s serve again. She then takes on the winner of the final match of the day between China’s Zheng Qinwen and Claire Liu from the United States.
“It was a really tough game,” said Kudermetova. “She played very well today. It was a good fight from both of us. I’m very happy because I gave everything today.”
She then takes on China’s Zheng Qinwen, Claire Liu’s 6-4, 7-5 winner from the United States.
In another quarterfinal, unseeded Russian Liudmila Samsonova defeated third-seeded Spaniard Garbine Muguruza 6-4, 6-2. China’s Zhang Shuai defeated Croatia’s Petra Martic 7-5, 6-2.
