Asa Ando's hopes for a dream run against Mikaela Shiffrin and the best in women's slalom at the Pyeongchang Olympics evaporated right out of the gate on Friday.

Ando's Olympic debut at the Yongpyong Alpine Centre ended in a little more than a dozen seconds when she missed a turn and failed to complete her first run.

"I basically just came here and it was all over before I knew it," the 21-year-old Ando said. "I wasn't as nervous as I thought I would be. I need to work on my turns and get stronger physically over the next four years. I want another shot."

The day did not turn out to be a great one for Shiffrin either as she not only failed to defend her title but also missed out on a medal altogether, finishing fourth. She was 0.40 second behind Sweden's Frida Hansdotter, who won gold in 1:38.63.

Swiss Wendy Holdener took silver (1:38.68), Katharina Gallhuber of Austria bronze (1:38.95).

A day after winning the giant slalom for the United States, Shiffrin, who was trying to become the first alpine skier -- male or female -- to win consecutive gold medals in the slalom, had a rough start to the first run, vomiting at the gates. She was fourth in 49.37.

"I don't know, it was kind of sudden," Shiffrin said of her unexpected sickness. "It almost felt like a virus kind of puking, less about nerves."

With the wind picking up, Shiffrin could not improve her time in the second run, clocking 49.66, and as she pushed over the finish line and saw her time, threw up her arms in anguish.

"Disappointed for sure," the 22-year-old said. "I didn't really feel like myself today. I did a lot of training runs, a lot of free skiing, I was trying to get my really good feeling back but it just wasn't there today to ski the aggressive way I need to be worthy of a medal."

Shiffrin couldn't pinpoint a reason for her performance.

"There are a lot of reasons. It's hard to put the blame on any one thing, there are a lot of things that come together to make it so I don't feel really good or feel the way I did today, it's just one of those things. It's life. You live and you learn."

"I was fighting for the medal yesterday and I came out on the right side and I was fighting today, although not really in the way that I wanted to, and I came on the wrong side."

"Somebody has to be in fourth place, it's OK."

Hansdotter became the third Swedish woman to win Alpine skiing gold, the nation's fourth gold medal of the Peyongchang Games. At 32 years and 65 days, she is the second oldest female Swede to win an individual event at the Winter Olympics.

For Hansdotter, the victory could not have been sweeter with Shiffrin so dominant in the World Cup this season. Hansdotter is seventh in the overall standings with less than half of Shiffrin's points.

"I knew it would be tough, Mikaela has been so strong this season," Hansdotter said. "I was maybe a little bit surprised. It's nice for me to beat her for once because she has been beating me so many times."
