Nanchang - Second-seeded Wang Qiang of China moved one match away from her first career WTA Tour title after beating Magda Linette 7-5, 6-2 on Saturday in the Jiangxi Open semi-finals.
Wang profited from her Polish opponent's 35 unforced errors.
It was Wang's first victory over third-seeded Linette at her fourth attempt.
"I didn't think too much about (the head-to-head)," Wang said.
"I just tried to play one shot at a time."
Sixth-seeded Zheng Saisai later dropped a set before beating Zhu Lin 6-3, 1-6, 6-2 in an all-Chinese semi-final.
"It was really tough, because yesterday I played very late, but everyone is here to support us," Zheng said.
"I'm very happy to get into the final for the first time."
Zheng ended her quarter-final close to midnight on Friday after a pair of lengthy quarter-finals that included Zhu's upset victory over top-seeded Zhang Shuai.
