ZHENGZHOU, China - Peng Shuai continued to justify her top seeding with a 6-3, 6-3 quarterfinal win over Zarina Diyas. The 23-year-old Kazakh, a former WTA World No.31, is on the comeback trail from a wrist surgery that had kept her out for seven months since Wimbledon last year.
Diyas was on a seven-match winning streak following her victory in last week's ITF $25,000 tournament in Nanning, and her exploits will see her rise back into the Top 200 on Monday.
The 27-year-old Duan beat unseeded Korean Jang Su Jeong 6-4, 7-5, which saw her take an overall 3-2 lead in the players' head-to-head, but she will have a tougher record to overcome in the next round. 25-year-old Wang, who eased past compatriot Liu Fangzhou 6-2, 6-3, has beaten Duan in nine of their 10 career meetings - with Duan's only victory coming via retirement, in the final of the Tianjin ITF $25,000 in 2015.
