It’s an all-American affair in the women’s beach volleyball final today in London. Misty May-Treanor and Kelly Walsh Jennings have ruled the sport for the last decade, winning Olympic gold in 2004 and 2008. In what may be their Olympic swan song, they’ll face the other American duo in the tournament, Jennifer Kessy and April Ross, who shocked a heavily favored Brazilian team in the semifinals. Also tonight in prime time, you’ll see the women’s 200 meter dash, where Americans Carmelita Jeter and Allyson Felix hope to get on the podium while 400 meter gold medalist Sanya Richards-Ross goes for another gold. You’ll also see the men’s 110 meter hurdles, where American Aries Merritt had the fastest first round time yesterday. The US men’s basketball team is four wins away from a gold medal. Their quarterfinal today pits them against Australia, a surprise qualifier that features former Husker star Aleks Maric.
