Caroline Wozniacki battled to a three-set win over Karolina Pliskova to reach the semi-finals of the Istanbul Cup.
The Danish top seed, who is yet to reach a WTA Tour final this season, won 6-1 3-6 6-2 and next meets France's Kristina Mladenovic, a 3-6 6-3 7-5 winner over former French Open champion Francesca Schiavone on Friday.
Croatian youngster Ana Konjuh continued her excellent week with a 6-4 1-6 6-1 victory over fourth seed and fellow teenager Elina Svitolina.
Sixteen-year-old Konjuh was playing in her first WTA quarter-final, and in her maiden semi-final she will face second seed Roberta Vinci, who thumped sixth seed Kurumi Nara 6-0 6-2.
