SAPPORO, Japan — Canada's two-time world pairs champions Meagan Duhamel and Eric Radford remain undefeated on the Grand Prix figure skating circuit after winning the NHK Trophy on Saturday.

Canadians Tessa Virtue and Scott Moir set a world-record score in the short dance.

Duhamel, from Lively, Ont., and Radford, from Balmertown, Ont., roared back from a second-place finish in the short program to claim gold with 204.56 points.

"There were some strong elements and there were some unfortunate mistakes," Radford said. "But sometimes we have to make these mistakes throughout the season so we can learn from them and they don't happen again."

Their program featured a triple twist, side-by-side triple Lutz and throw quad Salchow. They mistimed their first side-by-side jump and final lift.

"I don't know what happened with the lift," Radford said. "My body felt very tight and tired and we mismatched the timing on that last lift and it was a bit of a struggle."

Cheng Peng and Yang Jin of China were second at 196.87 and their compatriots Xuehan Wang and Lei Wang were third at 185.32.

Virtue, from London, Ont., and Moir, from Ilderton, Ont., scored 79.47 points to eclipse the previous world mark of 78.89 set by Meryl Davis and Charlie White of the U.S. at the 2014 Winter Olympics. Gabriella Papadakis and Guillaume Cizeron of France are second at 75.60 and Anna Cappellini and Luca Lanotte of Italy third (72.00).

"We had some work to do to bring our levels up for this competition and it was nice to get a couple of level fours," Moir said. "It felt pretty similar to what we've been doing in training and it is exactly what we wanted to accomplish with our performance."

Olympic champion Yuzuru Hanyu topped the 300-point mark to win the men's singles title. He landed three quadruple jumps to finish with 301.47 points, the highest score on the GP circuit this season.

Nam Nguyen of Toronto was eighth in men's singles, while Elladj Balde of Pierrefonds, Que., was 10th. Alaine Chartrand of Prescott, Ont., was 10th in women's singles.
