American teenager Red Gerard claimed gold in the men's slope style with a sensational final run at the Phoenix Snow Park in PyeongChang.
The 17 year-old did not have the best of starts when he made errors on his first two runs but he delivered when it counted most as he produced a flawless combination of a 1080 spin, a 1260 and a backside triple cork to record the winning score of 87.16.
