Teenage diva Kim Yu-Na set an unprecedable bar for successors here on Thursday, winning South Korea's first figure skating gold medal with record scores at the Vancouver Winter Olympics Games. The 19-year-old prodigy, nicknamed Skating Elf, earned 150.06 points for her flawless and infectious free skate, breaking the previous world record of her own for more than 16 points. Her overall score of 228.56 also set a new mark, adding to the short program record she hit on Tuesday. Trailing by 4.72 points after short program, Japan's sensation Mao Asada, also 19 years old, sustained the second place on podium with 131.72 points in free skate and 205.50 in total. Joannie Rochette of Canada, competing with a strong mind as her mother just passed away four days ago, took the bronze after claiming 131.28 for skating second to the last in front of the emotional crowd. The 24-yeaer-old Canadian has 202.64 points overall to beat Mirai Nagasu of the United States, 16, to the fourth place on a total of 190.15 points.
