On the night Kelly Clark qualified for a record fifth Olympics, so did a woman half her age.
Clark, the most decorated female halfpipe rider with three Olympic medals and more than 70 career wins, notched another victory in the fourth and final qualifier Saturday night.
Maddie Mastro, who was born after Clark made her X Games debut in 2000, finished third in Mammoth Mountain, Calif.
They join the previously qualified Olympic favorite Chloe Kim (also born in 2000) as the three U.S. women to grab automatic berths for PyeongChang.
