Chanatip Sonkham, a 21-year-old from Phatthalung, stormed her way into the semi-finals of the London Olympic Games taekwondo competition after stunning second-seeded Yang Shu-Chun 6-0 in the women's 49kg quarter-finals.
Yang, 27, from Chinese Taipei was one of the strong contenders for the crown, winning gold at this year's Asian Championships in Vietnam. She also took silver at the last year's world meet in South Korea.
In the semi-finals at 11.30pm Bangkok time on Wednesday, Chanatip will go up against Spain's Yague Enrique Brigitte, champion in three world meets - 2003, 2007 and 2009.
