Highlights of the fifth day of competition at the 2012 Summer Games:
-- Nathan Adrian made a name for himself by winning the 100-meter freestyle, lunging to the wall to edge James "The Missile" Magnussen by one-hundredth of a second -- the slightest margin possible -- to again deny Australia its first individual swimming gold.
-- Seventeen-year-old Missy Franklin won her second gold, swimming the leadoff leg of the 4x200 freestyle relay. Allison Schmitt and Dana Vollmer also got their second golds, and rounding out the relay team was Shannon Vreeland.
-- American Kristin Armstrong defended her title in the women's time trial, beating Judith Arndt of Germany by more than 15 seconds to get the gold.
-- Kohei Uchimura of Japan added Olympic gold to the gymnastics world titles he's won the last three years. Marcel Nguyen of Germany got the silver, and American Danell Leyva got the bronze.
-- Serena Williams routed No. 13 seed Vera Zvonareva, while Maria Sharapova, Victoria Azarenka and Kim Clijsters also advanced. Venus Williams was eliminated in the singles competition by No. 7-seeded Angelique Kerber of Germany but still has a shot at a gold with sister Serena in doubles. On the men's side, Britain's Andy Murray outlasted Marcos Baghdatis, Novak Djokovic beat Lleyton Hewitt, and Roger Federer won.
-- Host Britain picked up its first two gold medals of the games. Helen Glover and Heather Stanning won the final of the women's pair at the rowing regatta, and cyclist Bradley Wiggins, who won the Tour de France last month, took the time trial.
-- China completed a sweep of the synchronized diving events as Qin Kai and Luo Yutong won the men's 3-meter springboard to increase its total to 17 gold medals and 30 overall. The United States had 12 golds and 29 total medals.
Four badminton teams were kicked out of women's doubles for trying to lose on purpose to earn an easier matchup in the knockout round. A top IOC executive said the conduct strikes at the heart of Olympic competition. The eight doubles players from China, South Korea and Indonesia were cited by the Badminton World Federation for "conducting oneself in a manner that is clearly abusive or detrimental to the sport."
London's eccentric Mayor Boris Johnson provided comic relief by getting stuck midway on a zip wire at an open-air Olympic viewing site in east London. "Can you get me a rope? Get me a rope, OK?" he was heard saying in a video posted to the ITV News website. Said his office: "Unlike Team GB, he won't be bagging any gold medals today but he remains unbowed."
-- Women's gymnastics: women's all-around gold medal final.
-- Swimming: gold medal finals men's 200-meter backstroke, men's 200-meter individual medley, women's 200-meter breaststroke, women's 100-meter freestyle.
-- Men's beach volleyball: Rogers/Dalhausser (U.S.) vs. Benes/Kubala (Czech Republic).
-- Rowing: women's eight gold medal final.
