Winter Olympics: Chinese teenager Su Yiming wins snowboard gold in men's big air

China's Su Yiming claimed a second snowboard medal at the Winter Olympics as the teenager won a stunning gold in the men's big air event in Beijing.

Slopestyle silver medallist Su, 17, scored 182.50 to beat Norway's Mons Roisland and Canada's Max Parrot.
