The first day of Olympic competition in London’s Summer Games kicked off Saturday with an array of upsets. American Ryan Lochte bested teammate Michael Phelps and took the gold in the 400-meter individual medley. It was the first time Phelps, who finished fourth, didn’t medal in an event since 2000. Defending champ Norway lost to France in women’s handball in its opening game by a score of 24-23. Men’s cycling saw one of the most dramatic upsets of the day as 38-year-old Alexander Vinokourov of Kazakhstan beat out the heavily favored British team. Vinokourov had nearly retired last year when he broke his leg during the Tour de France. In tennis, American Serena Williams advanced to the second round of the singles draw with a straight-set win over Jelena Jankovic.
