Lee Hyun Il delighted the home crowd at the Badminton World Federation (BWF) Victor Korea Open after coming from behind to upset third seed Jan Ø. Jørgensen and reach the men's singles quarter-finals.
The 36-year-old showed his experience to claim an 18-21, 21-18, 21-13 win over his Danish opponent at the Seong-Nam Indoor Stadium in Seoul and now faces a last-eight encounter with 2015 runner-up Ajay Jayaram of India, a 21-15, 21-18 victor over China’s Huang Yuxiang.
It is the third time in five matches that Lee has beaten Jorgensen, who is more than seven years younger than the South Korean.
"I’m careful to maintain my muscle strength," said Lee.
"I also have to play smart and control the shuttle.
"I can feel I’m losing my strength a little, but as long as I can maintain my fitness, I can take on players of this level."
Lee’s compatriot Son Wan Ho also made the quarter-finals, beating India’s B. Sai Praneeth 21-9, 21-15.
Next up for him is Denmark’s Hans-Kristian Vittinghus, who overcame Chinese Taipei’s Tzu Wei Wang 21-13, 21-11.
The third seed in the women’s singles competition also crashed out today as Thailand’s Ratchanok Intanon suffered a 17-21, 17-21 defeat at the hands of China’s Chen Yufei.
Chen’s reward is a meeting with Japan’s Minatsu Mitani, who beat Japan Open champion He Bingjiao of China 18-21, 21-19, 21-16.
Another of the quarter-final encounters sees defending champion Sung Ji Hyun of South Korea go up against Indonesia Open champion Tai Tzu Ying of Chinese Taipei.
Number five seed Sung defeated Denmark’s Anna Thea Madsen 21-15, 21-14, while number four seed Tai overcame South Korea’s Kim Na Young 21-15, 19-21, 21-13.
Denmark had a double success in mixed doubles, with Kim Astrup and Line Kjaersfeldt and Anders Skaarup Rasmussen and Sara Thygesen prevailing in three-game battles.
Astrup and singles specialist Kjaersfeldt, originally a scratch combination at this year’s Indonesia Open, got the better of China’s Huang Kaixiang and Yu Xiaohan - 21-13, 12-21, 21-9.
Rasmussen and Thygesen surprised Japan’s Kenta Kazuno and Ayane Kurihara with a 17-21, 21-19, 21-17 victory.
