Thailand's Ratchanok Intanon will become the new women's world number one after winning a third Badminton World Federation (BWF) Super Series title in a row at the Singapore Open today.
The 21-year-old, the world champion in 2013, will replace Carolina Marin of Spain at the top of the rankings after her final victory over China's defending champion Sun Yu.
She came from behind to see off her opponent at the Singapore Indoor Stadium, 18-21, 21-11, 21-14.
Intanon also won the India Open and Malaysia Open and will be a huge hope for a Thai gold medal at the Rio Olympics.
In the men's competition, an unseeded final was won by Indonesian qualifier Sony Dwi Kuncoro.
The 31-year-old Olympic bronze medallist from Athens 2004 completed a remarkable triumph by beating South Korea's Son Wan-ho 21-16, 13-21, 21-14.
It was his first title at Super Series level for six years.
Every match Kuncoro played in Singapore went the distance, including his semi-final win over double Olympic champion Lin Dan of China yesterday.
China's Fu Haifeng and Zhang Nan clinched the men's doubles title, getting past Japan's Takeshi Kamura and Keigo Sonoda 21-11, 22-20.
Nitya Krishinda Maheswari and Greysia Polii of Indonesia won the women’s doubles title by walkover, due to an injury suffered by Japan's Misaki Matsutomo.
The ankle knock, sustained in the semi-finals yesterday, meant she couldn't take to the court with partner Ayaka Takahashi.
In the mixed final, South Korea's Ko Sung-hyun and Kim Ha-na got the better of China's Xu Chen and Ma Jin, 21-17, 21-14.
