The United States opens Day 8 with a narrow lead over China both in the total medal count and gold medal count. With another full day of swimming and tennis gold medals on the line, the USA will look to have another strong day on Saturday.
There are two tennis gold medal matches scheduled for Saturday and the United States will be involved in both. In the women's singles gold medal match, Serena Williams will take on familiar foe Maria Sharapova for the gold. The USA will also have a shot at gold in the men's doubles final as brothers Bob and Mike Bryan go for gold against the French team of Michael Llodra and Jo-Wilfried Tsonga.
The United States has already racked up 28 swimming medals, including 14 golds, but they will go for more on Saturday. The United States team holds the world record in the 4x100m medley relay and they will have a good shot at gold Saturday. The USA team posted the fastest qualifying score in the event. Other swimming finals on Day 8 include the women's 4x100m medley relay, the men's 1500m freestyle and the women's 50m freestyle.
