Thailand's Sujrat Pookkham and Japan's Sarina Satomi progressed to the women's wheelchair WH1 final at the Para-Badminton World Championships in Basel.
Pookkham faced the challenge of China's Menglu Yin in the semi-final stage of the competition at the St. Jakobshalle in the Swiss city.
Yin had already delivered a surprise by beating top seed Valeska Knoblauch of Germany in straight games in her quarter-final tie, which took place earlier in the day.
She was unable to repeat the feat in the last four as Pookkham emerged as a 21-16, 21-17 winner to progress to the final.
Pookkham will now face Satomi, after the Japanese player secured a 21-14, 21-13 victory over Switzerland's Karin Suter-Erath.
There were mixed fortunes for English players in the women's SS6 competition as Rachel Choong won her semi-final, but Rebecca Bedford suffered defeat.
Choong earned a 21-19, 21-12 win over the United States' Katherine Valli to advance to the final.
