PETALING JAYA: National women doubles shuttlers Pearly Tan-M. Thinaah were in ruthless form as they marched into the Indonesian Open semi-finals at the Istora Senayan in Jakarta on Friday (June 6).

Pearly-Thinaah took just 37 minutes to sent Japan's Rin Iwanaga-Kie Nakanishi packing with a superb 21-6, 21-18 win. 

It was their fifth win against the Japanese pair. 

They will face China's Li Yijing-Luo Xumin for a place in final. In their only encounter at the China Open last year, the Chinese pair won.
