Vail, Colo., teenager Mikaela Shiffrin made her Olympic debut Tuesday with a fifth-place finish in the women's giant slalom.

Slovenia's Tina Maze won her second gold medal of the Sochi Games, with Austria's Anna Fenninger coming in second and Germany's Viktoria Rebensburg, the defending gold medalist from Vancouver, finishing third.

Italy's Nadia Fanchini finished just off the podium in fourth place.

Maze earlier won gold in the downhill event, giving her a total of four Olympic medals in her career, and Fenninger earlier won gold in the super-G.

Shiffrin, 18, made her World Cup debut at age 15 in 2011 and later that year won the slalom title at the U.S. National Championships just after her 16th birthday, becoming the youngest American skier to claim a national alpine crown.

Shiffrin's best event is the slalom, in which she is the reigning World Cup and world champion. All of her seven World Cup wins have also come in the slalom.

She will compete in the Olympic slalom competition on Friday. If she wins gold in that event, she would become the youngest American to win an Olympic gold medal in alpine skiing.

In the giant slalom, her best result came with a second-place finish in a World Cup event at Beaver Creek, Colo., in December 2013, her first World Cup podium in the event. She came into Sochi sitting sixth this season in the World Cup giant slalom standings.
