Snowboarding great Shaun White brilliantly won his third Olympic gold today at the Pyeongchang Winter Games.Shaun, watched bronze medallist Scotty James wipe out before nailing a spectacular last run of the day to snatch victory from Japan's Ayumu Hirano. It was redemption for the 31-year-old veteran, who won gold in 2006 and 2010 also. It was a landmark win because it brought USA their 100th Winter Olympics gold stretching back to speed skater Charles Jewtraw in 1924. White, Chloe Kim, Jamie Anderson and Red Gerard have locked up all four snowboarding titles for America so far in Pyeongchang. High winds have badly disrupted, in particular, the skiing events, meaning a frustrating wait for America's Mikaela Shiffrin and her bid for multiple medals. But officials said they had no concerns about fitting in all the ski events before the closing ceremony on February 25. The unified Korean women's ice hockey team ended their Group B campaign with a 4-1 defeat to Japan, following 8-0 thrashings by Switzerland and Sweden. North Korea ended months of tension with the South last month when it agreed to attend the Games, sending 22 athletes including 12 players for the hockey team.
