Madison Chock and Evan Bates secured ice dance gold as the Four Continents Figure Skating Championships in Anaheim concluded.
The Americans began the free dance in second place, following the rhythm dance section of the competition.
Backed by a home crowd at the Honda Centre, Chock and Bates produced a series of impressive lifts and footwork.
Their efforts were rewarded with a total of 126.26 points in the free dance, giving them an overall tally of 207.42.
The total proved enough to secure gold at an International Skating Union (ISU) Championship event for the first time, following a series of silver and bronze medals.
The achievement came after a 10 month break from competition as Chock recovered from ankle surgery, which led to the duo only resuming competition again last month.
"It feels incredible," Chock said.
"We didn't set any expectations as far as placement, because that's not why we are skating.
"We have this new found joy and happiness when we are skating and we want to share that and that is our main goal this season."
Canada's Kaitlyn Weaver and Andrew Poje claimed the silver medal, with the pairing scoring 123.37 points in the free dance.
The score gave the duo an overall total of 203.93.
Piper Gilles and Paul Poirier rounded off the podium, as the Canadians finished with a total of 202.45.
There was disappointment for Madison Hubbell and Zachary Donohue, who led after the rhythm dance.
The Americans would slip outside the medal positions after the free dance, as they finished on 201.66.
The ISU event features athletes from the Americas, Asia, Africa and Oceania but not Europe.
A total of 88 skaters from 14 countries competed over the four days.
