Kim Yu-na finished first in the short program of the ladies' figure skating at the Sochi 2014 Winter Olympics on Thursday.
Her performance to "Send in the Clowns" earned her 74.92 points, of which 39.03 is the technical elements score and 35.89 the program components score.
She is ahead of Adelina Sotnikova of Russia, who scored 74.64 points, and Italy's Carolina Kostner, who got 74.12.
"I was nervous during the warm-up. I started without confidence in my jumps. But I was perfect almost all the time I practiced the short program, so I thought it would be okay if I could perform as I used to," Kim said afterwards.
Russia's emerging star Yulia Lipnitskaya fell on her triple flip attempt and had to content herself with fifth place and 65.23 points. 2010 Olympic silver medalist Mao Asada of Japan gave a disappointing performance, faltering on all three jump elements, and is now in 16th place with 55.51 points.
All three Korean skaters qualified for the free skate on Thursday. Kim Hae-jin is in 18th place with 54.37 points and Park So-youn in 23rd with 49.14 points.
Kim will skate last in the free skate.
