Seyoung Ahn defeated Gregoria Tunjung (Indonesia) 2-0 (21-14 23-21) in the semifinals of the tournament held in Singapore on the 1st.

Ahn Se-young, who defeated world number 9 Tunjung in 43 minutes on this day, will attempt to win for the third time this year, following the Malaysian Open in January and the French Open in March.

Ahn Se-young, who suffered ups and downs due to a knee injury after winning the gold medal at the Hangzhou Asian Games last year, was eliminated in the semifinals at the All England Open in March and in the quarterfinals at the Asian Championships in April after the French Open.

He is continuing his progress through this tournament and next week's Indonesia Open in his final practice test before the Paris Olympics. He will also challenge to win the Singapore Open for the second year in a row in the final on the 2nd.

In the final, Ahn Se-young meets world number 2 Chen Yufei (China).

Chen Yufei was called Ahn Se-young's 'natural enemy' in the past, but in the final match of the Hangzhou Asian Games, Ahn Se-young won despite 'fighting spirit' and took the gold medal.

In terms of opponent record, Ahn Se-young is slightly behind with 7 wins and 11 losses.

Meanwhile, the mixed doubles team of Seo Seung-jae (Samsung Life Insurance) and Chae Yu-jeong (Incheon International Airport) lost 0-2 (16-21 18-21) to world number one Zheng Si-wei and Huang Ya-chong (China) in the semifinals on this day and did not advance to the finals. 섯다
