2012 Summer Olympics Best and Worst moments

The Williams sisters and Bryan twins made it a sweep for the U.S. in tennis doubles gold medals at the 2012 Olympic Games. This is the first men's doubles gold medal for the U.S. since 1988. However, the U.S. women have won doubles gold every year since tennis became an Olympic sport, except in 2004, when Serena couldn't play with Venus due to injuries.
