In her season edit, it's clear Kelly and her eight-year-old brother, Henry, are the kids to watch. Rookie Hailey Langland, 15, of California picked up bronze in her first trip to X Games with her 88-point second run.
Sildaru, of course, had to celebrate her win just a little.
The 13-year-old YouTube sensation from Estonia became the youngest Winter X Games gold medalist on Friday, spinning her trademark switch 900s both left and right to earn the biggest win of her career, which began with internet videos showing her technical prowess as a precocious 10-year-old spinning tricks that challenged pros.
Joe Parsons earned his fourth X Games gold medal by performing this feat of athleticism on a snowmobile. The silver and bronze medalists in the Snowmobile Freestyle Final were Heath Frisby and Brett Turcotte, respectively.
Parsons scored a 90 in his first run, and it was because of this insane backflip, with footage courtesy of the X Games.
Sildaru's performance was impressive to Tiril Sjåstad Christiansen, who herself set the mark for the youngest women's ski champion in X Games history when she won the event in 2013. From the first day I saw her ski, I was just blown away.
Anderson finished second overall in the Women's Snowboard Slopestyle competition, scoring 89 points on her third and final ride of the finals. History has been made through the first two days, and with more medals to be given out Saturday, more records could break.
