Indonesia's men reach quarters at Korea Open [font=Arial, Helvetica] The Jakarta Post, Jakarta Three Indonesian doubles badminton pairs have advanced to the next stage of the Korea Open but two of them now go head-to-head in the quarterfinals. Sigit Budiaro and Tri Kusharyanto were extended to a three-set encounter before stopping Nathan Robertson and Anthony Clark of England. The Indonesians won 15-11, 6-15, 15-12, the tournament's website said. Meanwhile, a convincing win was chalked up by Luluk Hadiyanto and Alven Yulianto, who upset second seeds Cai Yun and Fu Haifeng, 15-12, 7-15, 17-14. Both pairs will now have to face off in the quarterfinals with the winners, taking on either Yim Bang-eun and Kim Yong-hyun of South Korea or Jim Laugesen and Carsten Mogensen of Denmark. The third pair, Flandi Limpele and Eng Hian needed only half an hour to dispatch Jung Jae-sung and Jung Hoon-min 15-4, 15-10. They now face the daunting task of overthrowing top seeds Kim Dong-moon and Ha Tae-kwon of South Korea. While the men marched ahead, their female compatriots were already tumbling, with Jo Novita and Lita Nurlita the latest to exit. Jo and Lita suffered a shocking 15-3, 15-1 loss to Chien Yu-Chin and Cheng Wen-Hsing of Chinese Taipei. Nova Widianto and Vita Marissa are still nurturing Indonesia's hopes in the mixed doubles, going through with a 15-10, 15-0 over Svetoslav Stoyanov and Victoria Wright of France. But in the next stage they will face top seeds Kim Dong-moon and Ra Kyung-min, to whom the Indonesians have lost in all of their four meetings. Indonesia is not sending players in the women's singles while in the men's singles, injury-plagued Taufik Hidayat had to exit early at the hands of Sergio Llopis of Spain. He withdrew from the match trailing 8-0 in the third set.[/font]
