JEONGSEON, South Korea -- Michelle Gisin had been perplexed by the slalom for some time, showing a flair for the discipline but rarely putting together an exceptional full run.

That is until gold was on the line.

The Swiss ski racer captured the women's Olympic Alpine combined Thursday with an aggressive slalom run to beat Mikaela Shiffrin of the United States.

Lindsey Vonn, the leader after the downhill portion, made a mistake early in the slalom and didn't finish in what was probably the final race of her Winter Games career.

Gisin finished in a combined time of 2 minutes, 20.90 seconds to eclipse the silver medalist Shiffrin by 0.97 seconds in overcast conditions and with the artificial lights turned on for extra visibility. Wendy Holdener of Switzerland was 1.44 seconds back to earn the bronze.

"I tried to put my heart into that run," Gisin said. "It's insane."

And another medal for the Gisin household. Her older sister, Dominique, finished in a tie for downhill gold four years ago in Sochi.

"The best ever. It makes everything more beautiful," Michelle Gisin said. "She gave her all. I gave my all. We did it."

Speaking of medals, add one more to Shiffrin's burgeoning collection. She won Olympic gold in the giant slalom a week ago and captured the slalom title at the 2014 Sochi Games.

"It's a nice way to end the Olympics," said Shiffrin, who narrowly missed a podium spot in the slalom, finishing fourth. "I started off with a bang, and ending with a medal on the podium is really cool."

After crossing the finish line, Gisin celebrated with exuberance as Shiffrin clapped for her. Gisin was in third position after the downhill leg and had a 1.21-second advantage over Shiffrin.
