Canada's top striker Christine Sinclair made a brace as Canada edging Ghana 4-0 to keep their qualifying hopes alive.

Canada lost to group favorites Norway 2-1 in their first match, and the three points against Ghana are crucial for advancing to the knockout stage.

Sinclair headed a Kara Lang right wing cross against the crossbar before the ball bouncing into the net in the 16th minute, and drilled home comfortably after Lang rounded the Ghanaian keeper Memunatu Sulemana and fed an unselfish cross in the 62th minute.

Midfielder Sophie Schmidt added another 10 minutes into the second period, before fullback Martina Franko took the last from a corner.
