United States overcame rivals Canada to maintain their perfect start to the International Ice Hockey Federation Women’s World Championship in Espoo.

Both teams had won their opening Group A match at the Finnish city's Metro Areena.

The US edged the opening period with Hilary Knight and Kendall Schofield finding the net, either side of a strike from Canada’s Sarah Nurse.

Canada levelled again when Brianne Jenner scored early in the second period, but Annie Pankowski then fired the US 3-2 in front.

Despite Canada’s best efforts, they were unable to draw level for a third time.

The US, who have won every world title since 2013 and secured gold at the 2018 Winter Olympic Games in Pyeongchang, top Group A with two victories.

Canada lie in second place.
