ZHANGJIAKOU, China (AP) — A trio of Americans won gold in the Olympics’ first mixed team aerials event to give the United States its first medals in the freestyle skiing discipline in a dozen years. Ashley Caldwell, Christopher Lillis and Justin Schoenefeld each earned their first Winter Games medals. Lillis’ back double full-full-double full was given the highest score of any trick in the finals and the U.S. title was assured when Schoenefeld followed with a clean back double full-full-full. The 28-year-old Caldwell is in her fourth Olympics but has never finished higher than 10th. She and Schoenefeld have been dating for about three years.
