Pairs world champions Aliona Savchenko and Robin Szolokowy rebounded from a rusty short program to win the Skate America event Saturday night in Everett, Wash.
The German team rallied from second spot to take the free skate and post an overall score of 180.77 points.
Americans Keauna McLaughlin and Rockne Brubaker earned second with a total of 172.69.
The Russian pair of Maria Mukhortova, who led after the short program on Friday, struggled in the long program to finish third at 167.67.
Meagan Duhamel of Lively, Ont., and Craig Buntin, from Kelowna, B.C., had a solid showing in the event, placing fourth with 159.80.
Despite their victory, Savchenko and Szolokowy looked ragged on a triple salchow jump and on an ensuing spin.
But the German team recovered to impress the judges with a creative skate.
Mukhortova and Trankov, silver medallist at last season's European championships, couldn't follow up their fine performance on Friday.
Trankov tumbled on a triple salchow during the team's second element. Mukhortova then tumbled on a throw triple loop and fell again after a triple toe loop.
"It was difficult for us to perform last in the competition," Mukhortova said. "We have a lot of competitions ahead of us and we can improve a lot."
