LENZERHEIDE, Switzerland (Reuters) - Ted Ligety rounded off his season with another giant slalom win on a perfect day for the American team at the Alpine ski World Cup finals on Saturday.

Triple world champion Ligety, who secured the giant slalom World Cup last weekend, beat overall title winner Marcel Hirscher of Austria by 0.37 seconds to take his sixth win of the season in the discipline.

His win came an hour after teenage team mate Mikaela Shiffrin had taken the women's slalom World Cup with victory in the event's final race at this Swiss resort.

Frenchman Alexis Pinturault was third in the men's race on the Silvano Beltrametti course, his third podium place in succession in giant slalom.

The World Cup season concludes with the men's slalom and the women's giant slalom on Sunday.
