Taiwanese taekwondo athlete Lin Ting-yueh downed four opponents in four matches Tuesday to win a gold medal in the men's under-58 kg event in the 2010 Taekwondo World Championships. It was Taiwan's first gold won in the International Taekwondo Federation (ITF) event that opened July 4 in Cheongju, Chungcheongbukdo province, South Korea. Lin defeated Jeff Hurben of the United States 4-0 and 4-0 at the final, Horacio Daniel Obon, head coach of the Taiwan team, told the Central New Agency. It was a tough fight, Hurben became exhausted and Lin knocked him down with a head butt, Obon said. A seven-member Taiwan team -- four men and three women -- is competing in the world championships, which have attracted more than 60 taekwondo athletes from over 60 countries. The competition will run though July 8.
