Taipei, Sept. 6 (CNA) Taiwan's Hsieh Su-wei and her Spanish partner Anabel Medina Garrigues eased past Hsieh's countrywoman Chuang Chia-jung and Zhang Shuai of China in straight sets Wednesday to reach the semifinals of the women's doubles at the U.S. Open.
The Taiwan-Spain pair won the match 6-2, 6-1 in one hour, three minutes, winning five of the six break points to their opponents' none.
Their first and second serve winning rates were 68 percent and 63 percent, respectively, compared with the Taiwan-China duo's 59 percent and 38 percent.
The win put Hsieh, 26, on par with her previous best performance in Grand Slam doubles when she made it into the semifinals at the 2009 French Open.
She congratulated Chuang, who paired with her at the London Olympic Games, and Zhang on playing a good match. "Thanks for letting us win," Hsieh said on her Facebook page.
Hsieh and Medina Garrigues will play against the third-seeded Czech duo of Andrea Hlavackova and Lucie Hradecka, who defeated Sabine Lisicki of Germany and Peng Shuai of China 6-3, 6-1.
The Czech pair eliminated Hsieh and Chuang in the women's quarterfinals at the London Games.
