Mattingley and Schaerer new slopestyle Junior World Champions
The 17-year-old shredder from Park City rocked the women's slopestyle comp in the Park Palu scoring the day's high of 88.00 in her second run.
Mattingley thus claimed her career's first big title at her first Junior Worlds start edging off Elli Pikkujamsa (FIN, 82.75) and Katie Ormerod (GBR, 80.25) to second and third respectively.
On the men's side, Schaerer, who had taken Bronze in the halfpipe event just a few days ago, stepped it up in his favourite discipline.
The 17-year-old from Münsingen earned 94.25 in his second run consisting of frontside blunt 450 to switch backside 900, hardway 1080, backside lipslide as well as a final frontside lipslide 270 and thus was able to beat Rowan Coultas (GBR). As a result, he became the most-successful freestyle snowboarder of the 18th FIS Snowboard Junior World Championships.
British styler Coultas had been in the lead after run one with 90.25 but had to settle with Silver. Norway's Stian Kleivdal rounded out the podium as third (86.50).
