COVENTRY, England (AP) -- Christine Sinclair scored two second-half goals Saturday to help Canada beat South Africa 3-0 in women's Olympic soccer.
Sinclair scored in the 58th and 86th minutes at the City of Coventry Stadium after Melissa Tancredi put Canada in front in the seventh minute.
Canada is third in Group F with three points, one point behind both Japan and Sweden. The two best third-place teams advance to the quarterfinals along with the top two teams in each group.
South Africa has zero points after losing its first two games and faces world champion Japan in its last game. Canada plays Sweden.
"It's always great to get the win," Canada midfielder Desiree Scott said. "South Africa came out and gave us a battle at times but we scored some great goals. Now we need to step it up another notch and get a result."
Canada took the lead when Tancredi slotted the ball past goalkeeper Thokozile Mdaweni for her second goal of the tournament.
Tancredi almost had another score in the 12th but headed it wide from close range.
South Africa's best chance of the first half came in the 22nd when Andisiewe Mgcoyi's close-range shot forced Karina LeBlanc to make the save.
Canada kept pressuring in the second half and Mdaweni made a good stop in the 55th to prevent Sinclair from scoring. But the captain doubled Canada's lead three minutes later with a powerful header.
Diana Matheson came close to adding to the lead, but her long-range effort thundered against the cross bar.
Sinclair sealed the win with four minutes left.
South Africa coach Mkhonza Mkhonzana said his players have been to overwhelmed by playing at the Olympics.
"The stage is too big for us," he said. "We make mistakes in crucial areas and got punished and when the other team makes mistakes in the same areas we don't punish them."
