Mikaela Shiffrin might as well be dancing or flying.
That’s what skiing is like for the American teenager these days. The victories and milestones keep piling up, fortifying a US team that is without Lindsey Vonn and Bode Miller.
A day after Ted Ligety became the first man to win three gold medals at a world championships in 45 years, Shiffrin became the youngest woman in 39 years to win the slalom title Saturday in Schladming, Austria.
At the age of 17 years, 340 days, Shiffrin shook off a serious bout of nerves to edge local hope Michaela Kirchgasser from the lead before a crowd of 30,000 fans who were nearly all supporting the Austrian.
‘‘Doing what I did on the hill today, especially in the second run, just skiing, is like dancing or flying,’’ Shiffrin said. ‘‘There’s so many ways that I can describe it. But it just is, and it works for me.
‘‘It’s been 17 years in the making and everybody says that it comes too fast but it seems like it’s been forever for me . . . I am just doing what I do and I don’t want to wait.’’
The only slalom world champions younger than Shiffrin were Hanni Wenzel of Liechtenstein in 1974 and Esme Mackinnon of Britain in 1931. Overall, Shiffrin is the youngest women’s world champion since American Diann Roffe-Steinrotter, who was 21 days younger when she won the giant slalom title in 1985.
Shiffrin won her first three races this season to lead the World Cup slalom standings and set up big expectations for her first major championship. That explains the jitters before the opening run in which she placed third.
During the podium ceremony, Shiffrin breathed heavily but held back tears as she sang the American anthem, with her father videotaping the scene. Shiffrin’s older brother, Taylor, was also there.
Shriffrin’s parents were both ski racers, but it was when Taylor started to race that she realized she wanted to be a part of the sport.
Shiffrin grew up in Colorado and moved to New Hampshire when she was 12. She started skiing in powder in the West then got used to rougher and icier conditions in the Northeast. She credits former US coach Kirk Dwyer for shaping the way she skis while at Burke Mountain Academy in Vermont.
