Diana Taurasi and Maya Moore each had 12 points for the Americans, who dominated the boards with 43 rebounds to Canada's 25.

The USA women have won seven of the past eight gold medals and Friday's win was their 45th in a row in Olympic competition.

The USA has been unstoppable in Rio -- they beat Senegal by a 65-point margin, the biggest ever for an American women's team in the Olympics -- and nothing short of a historic upset looks likely to prevent them from repeating yet again.

The USA is now 4-0 in Group B and Canada 3-1. The Canadians will be hoping for a win Sunday over 2-2 Japan to secure a different bracket than the Americans in the knockout phase.

Miranda Ayim was Canada's top point-producer with eight.

Canada hung tough early and was down by a point to start the second period, but Moore scored eight in the 15-2 USA run that followed.

Earlier, Serbia beat China 80-72, paced by Ana Dabovic's 23 points and Sonja Petrovic's 20.
