China's Sui Wenjing and Han Cong, two-time world junior champions, captured the pairs title at the ISU Four Continents championship by winning Sunday's free skate final.

The Chinese duo, who also won the short programme on Saturday, scored 135.08 points to claim the free skate and secured the overall crown with 201.83 points to 185.42 for reigning US champions Caydee Denney and John Coughlin.

Denny and Coughlin scored 122.07 to finish second in the free skate with another US duo, Mary Beth Marley and Rockne Brubaker, third on 116.47 and third overall at 178.89.

Canadians Meagan Duhamel and Eric Radford were fourth overall, with Japan's Narumi Takahashi and Mervin Tran fifth in the event, a tune-up for next month's world championships in Nice, France.

Reigning world ice dance champions Meryl Davis and Charlie White of the United States will face reigning Olympic chapions Tessa Virtue and Scott Moir of Canada in the free dance final later on Sunday.

Davis and White, the 2010 Winter Olympic runners-up, are defending Four Continents champions.
