Thailand secured their most-awaited victory at the World University Games when their badminton hero Boonsak Ponsana won the men's singles over Chen Hong from China.
Boonsak, nicknamed Superman in Thailand, revenged his loss to Chen in July's Thai Open men's singles final, beating Chen 17-21, 21-15, 21-17 in 56 minutes.
His compatriots Phattapol Ngensrisuk and Sudket Prapakamol defeated Hsieh Yu-Hsing/Tsai Chia-Hsin from Chinese Taipei 17-21, 21-17, 21-14 in the men's doubles final.
China's loss was somehow offset by the women's singles victory when teenager Wang Yihan brushed aside Cheng Shao-Chieh from Chinese Taipei 21-12, 21-17.
Chinese Taipei participated in four of the five finals and Chien Yu-Chin/Cheng Wen-Hsing, ranked fourth in the world, breezed past Tian Qing/Pan Pan of China 21-9, 21-13 in a one-sided women's doubles final in less than 30 minutes.
South Korean pair Yoo Yeon Seong/Kim Min Jun clinched the mixed doubles over Fang Chieh- Min and Cheng Wen-Hsing from Chinese Taipei 21-19, 13-21, 21-17.
In the most eye-catching men's singles final, Boonsak, 25, had to come back from behind in his battle against twice All-England champion and double Thomas Cup winner Chen.
Losing the opening set, Boonsak trailed at 0-4 before clawing back to level at 6-6 in the second.
The pair exchanged a dozen of shots before Boonsak grabbed the lead at 7-6, which drew deafening cheers from the capacity spectators in the Gymnasium 2 on Thammasat University.
"Boonsak did a great job and was in peak form today, maybe because he was competing on home soil," said the 28-year-old Chen, who left the Chinese national team early this year but kept competing and now ranked second in the world.
"I committed many errors today. I found that the speed of the shuttle was quite low and felt a little bit unadapted," he said.
Newly crowned Singapore Open titlist Boonsak went on to clinch the second set and opened the decisive set with a 4-1 advantage before the fast-paced Thai cashed in on the Chen's errors to lead at 19-15.
