Top-ranked Kento Momota of Japan clinched the men’s singles title at the Korea Open badminton tournament on Sunday with a win over No 2 Chou Tien-chen of Taiwan.

The 25-year-old downed Chou 21-19, 21-17 in a final that lasted 53 minutes.

Momota, with over 300 wins under his belt, saw his career descend into controversy in 2016 when he was suspended for more than a year for visiting an illegal casino and was denied a spot at the 2016 Rio Olympics.

The Japanese star, who was world No 2 at the time, has since worked his way back to the top and Sunday’s win raises his Olympic hopes a year ahead of the Tokyo Games.

In the women’s final, China’s He Bingjiao defeated Ratchanok Intanon of Thailand 18-21, 24-22, 21-17.

South Korea dominated the women’s doubles, with Kim So-yeong and Kong Hee-yong beating compatriots Lee So-hee and Shin Seung-chan 13-21, 21-19, 21-17.

Indonesian pair Fajar Alfian and Muhammad Rian Ardianto defeated Takeshi Kamura and Keigo Sonoda of Japan 21-16, 21-17 to clinch the men’s doubles title.
