Alexandra Trusova shrugged off a foot complaint and overcame a strong challenge from fellow Russian teenager Daria Usacheva to win the women’s title at Skate America in Las Vegas.

There were doubts before the event that Trusova would even take to the ice in the American city due to the injury.

But the 17-year-old refused to hold back as she topped the standings after the short programme before securing victory today at the season-opening International Skating Union Grand Prix of Figure Skating event.

Trusova opened her free skating routine with a quad Lutz before reeling off a triple loop, double Axel-triple toe-loop, triple Lutz-triple toe, triple flip-Euler-triple Salchow and another triple Lutz.

The world bronze medallist scored 154.68 points as she racked up 232.37 overall to win with 15 points to spare.

"I skated my programme with a very easy content, I did only one quad," said Trusova.

"I am happy that I was able to skate clean but in the future I want to do more quads.

"I was a bit more nervous, because my preparation wasn’t as good because of the injury and I did not do many run-throughs of my programs."

Usacheva marked her senior Grand Prix debut with a silver medal after scoring 217.31.

The 15-year-old produced five clean triple jumps and level-four spins with her only error coming when she stepped out of a triple flip.

Last year’s world junior silver medallist placed fourth in the free skating programme but managed to do enough to seal second spot as You Young of South Korea clinched bronze with 216.97.

"I am a bit upset with the mistakes that I made in the free skating but I am happy with my result," said Usacheva.

"For me, this competition was a bit harder [than events in Russia] because it was my first senior international."

Madison Hubbell and Zachary Donohue of the United States captured their fourth consecutive Skate America ice dance title after totalling 209.54.

Compatriots Madison Chock and Evan Bates secured silver with 208.23 while Canadians Laurence Fournier Beaudry and Nikolaj Sørensen clung on to third spot with 190.13 as Spaniards Olivia Smart and Adrian Diaz fell agonisingly short of picking up a medal.

"Something clicked this morning and I felt great in practice, and I just wanted to keep that feeling and skate for myself and be there for Zach, be present in the performance from the beginning to the end," said Hubbell.

"I think we've accomplished our goals in doing so and also accomplished the other goal which was to come out with gold."
