American teenager Mikaela Shiffrin has won gold for the United States in the women's slalom, becoming the youngest ever winner in the event

The 18-year-old skier finished the course in a time of 52.62 seconds, ahead of defending champion Maria Hoefl-Riesch of Germany, who finished in second place to take a record-equalling fourth career alpine gold.

Slovenia's Tina Maze took the bronze medal, narrowly edging out Bernadette Schild of Austria.

As well as becoming the youngest Olympic gold medallist in the event, Shiffrin also becomes the first American women's slalom champion in 42 years.
