Gold medallist Gabrielle Douglas of the US waves as she stands on the podium after the women's individual all-around gymnastics final in the North Greenwich Arena at the London 2012 Olympic Games Thursday. — Reuters LONDON – Make it a pair of Olympic gymnastics gold medals for Gabby Douglas, who added the all-around title Thursday to the one she won with the US team two nights ago at the London Games. Douglas became the third straight American to win gymnastics' biggest prize, taking the lead on the first event Thursday and never really letting anyone else get close. She finished with a score of 62.232, less than three-tenths ahead of Viktoria Komova of Russia. Aliya Mustafina won the bronze. Douglas brought the house down with her energetic floor routine, and US teammates Jordyn Wieber, McKayla Maroney and Kyla Ross jumped to their feet and cheered when she finished. Douglas flashed a smile and coach Liang Chow lifted her off the podium. Ki Bo-bae wins archery gold South Korea's Ki Bo-bae won gold in the women's individual archery Thursday after Mexican Aida Roman lost her nerve in a tense sudden-death shoot-off for the Olympic title. It was Ki's second title of the games after her gold as part of the South Korean women's team. With the scores locked at 5-5 in sets, the top-seeded Ki only managed an eight in the decisive shoot-off for the individual title. But just needing to put her arrow in the yellow center ring, Roman lost out at the end as she also shot an eight, and her arrow was further away from the center than Ki's. The gold was South Korea's third medal in the archery. The men's team won bronze. Roman's silver was the second medal of the day for the young Mexico team after 18-year-old teammate Mariana Avitia beat American veteran Khatuna Lorig 6-2 in the bronze match at Lord's cricket ground. First judo gold for US Kayla Harrison became the first American to win an Olympic judo gold medal Thursday, beating Gemma Gibbons in the final of the women's 78-kilogram category. Harrison dominated the final from the start, getting a stronger grip on Gibbons and managing to throw her twice. It was the second American judo medal this week, as teammate Marti Malloy won a bronze in the women's 57-kg division. The 22-year-old Harrison is a former world champion and was in top form on Thursday. She dispatched several of her opponents with a match-ending ippon, one in less than a minute. The bronze medals were won by Audrey Tcheumeo of France and Mayra Aguiar of Brazil. Tagir Khaibulaev of Russia won the men's 100-kg gold with Russian President Vladimir Putin and British Prime Minister David Cameron looking on. Khaibulaev defeated defending champion Tuvshinbayar Naidan of Mongolia with a match-ending ippon throw that Putin and Cameron both stood to applaud. The 28-year-old Khaibulaev has not lost at any international event since taking the last world championship title. Russia has already won two judo gold medals and a bronze earlier this week. They are the country's first judo golds since the breakup of the Soviet Union. The bronze medals were won by Dimitri Peters of Germany and Henk Grol of the Netherlands. — Agencies
