The second weekend of competition for the 2012 Summer Olympics means continued jostling between the United States and China for the overall medal lead.
As of late-afternoon Greenwich Mean Time in London, the two countries are knotted at 48 overall medals, with the U.S. extending their lead in number of gold medals won based on Friday's swimming results.
On Saturday, however, the Chinese kept pace, winning the gold medal in women's doubles badminton over Japan.
The Chinese duo of Tian Qing and Zhao Yunlei defeated Mizuki Fujii and Reika Kakiiwa of Japan 21-10, 25-23 to win the event on Saturday afternoon that overall was marred by scandal and controversy.
In a more traditional and popular raquet sport, the U.S.'s Serena Williams cruised past Russia's Maria Sharipova in the women's tennis singles event at Wimbledon. Sharipova's silver medal was the 13th overall for the country, giving them the second most silver medals so far in the Olympics.
Shortly after Williams captured gold, American men's doubles players Mike Bryan and Bob Bryan did the same, defeating France's Michael Llodra and Jo-Wilfried Tsonga.
Here's a more complete look at the medal count:
United States: 48 (24 gold, 11 silver, 13 bronze)
China: 48 (22, 16, 10)
Great Britain: 26 (11, 7, 8)
Russia: 25 (3, 13, 9)
France: 22 (8, 6, 8)
