The United States and Brazil advanced to the quarterfinals of the Olympic women's soccer tournament as group winners despite being held to disappointing draws in their final pool matches Tuesday. Canada remains the only team left with a 100 percent winning record after two goals from captain Melissa Tancredi secured a 2-1 upset win over Germany 2-1 and top spot in Group F. Host Brazil rested seven starters, including its influential captain Marta, but despite dominating possession was held to a goalless draw by South Africa in Manaus. The point for Brazil was enough to ensure top spot in Group E and set up a last eight clash Friday with Australia, which advanced from Group F as one of the best third placed teams following a 6-1 demolition of Zimbabwe. Germany went through in second place in Group F, despite its defeat by Canada in Brasilia, and will now play China in the last eight after the Asians drew 0-0 with Sweden in Group E. The United States will face the Swedes, who finished third in Group E, in knockout action Friday. The triple reigning champion Americans will hope for a better showing from goalkeeper Hope Solo, who was at fault for both Colombian goals scored by Catalina Usme. Solo let the ball squirm through her legs for Colombia's opener after 26 minutes and then completely missed a cross ball for the second in the final minute. The US topped Group G ahead of France, which set up a quarterfinal with Canada in Sao Paulo after easily beating New Zealand 3-0 Tuesday. While the goals flowed for France, Brazil struggled to convert their chances against South Africa even after introducing Marta for the second half in Manuas. South Africa had a good shout for a penalty turned down when a cross hit the hand of Brazilian defender Monica, while host's goalkeeper Aline produced a marvelous save to defy Thembi Kgatlana after 70 minutes. Brazil is looking for its first gold medal in women's football after silver showings at the 2004 Athens Games and four years later in Beijing. In both finals it lost to the United States, who it could face in the semifinals in Rio. The men's tournament continues Wednesday, with Brazil needing to beat Denmark to progress to the quarterfinals.
