Guo finished with 488.1 points, with France's Celine Goberville claiming silver in a shootoff with Ukraine's Olena Kostevych after both finished on 486.6. Guo threw her hands over her face in disbelief after scoring a 10.8 - just shy of the maximum 10.9 – to overhaul Goberville, who held a 0.5 advantage going into the 10th and decisive round. The 25-year-old Frenchwoman was only able to muster a disappointing 8.8 with her final effort. Guo's victory followed countrywoman Yi Siling's triumph Saturday when she won the first gold of the Games in the 10m air rifle as China made a strong start to London 2012. Later, Kimberley Rhode etched her name into the annals of great American Olympians when she easily won the women's skeet gold medal to become the first US competitor to win individual medals in five consecutive Games. Rhode finished with a total of 99 points, only missing one of the 100 clays she shot at all day, ahead of Wei Ning of China on 91 with Slovakia's Danka Bartekova (90) taking bronze after a shootoff with Marina Belikova of Russia. The American's total bettered her previous shared Olympic record of 93, which she set at the Beijing Games four years ago en route to a silver medal after a three-way shootoff. SK dominates archery South Korea won the Olympic women's team archery title for the seventh consecutive time on Sunday after beating China in the final at Lord's cricket ground. The Korean trio of Ki Bo-bae, Lee Sung-jin and Choi Hyeon-ju scored 210 points from their 24 arrows to beat the Chinese by a single point. South Korea's women have now won 13 of the last 14 archery gold medals. NK bags w-lifting gold North Korea's Om Yun Chol won Olympic gold after matching the world record in the clean and jerk, beating Chinese world champion Wu Jingbiao into second place. Eighteen-year old Valentin Hristov of Azerbaijan won the bronze. Earlier, Kazakhstan's Zulfiya Chinshanlo won her country's second gold medal with a world record in the women's 53 kg section. Taiwan's Hsu Shu-Ching took the silver, while the bronze medal went to Cristina Iovu of Moldova. Szilagyi wins saber gold Fencer Aron Szilagyi of Hungary won the gold medal in the men's individual saber by beating Diego Occhiuzzi of Italy 15-8 after the top four seeds all stumbled out before the semifinals. Nikolay Kovalev of Russia defeated Rares Dumitrescu of Romania 15-10 to win bronze. Two fresh dope cases Two athletes saw their Olympic hopes cut short Sunday after being suspended from the London 2012 Games for using banned performance-enhancing drugs, taking the tally of doping offenders after two days of competition to three. St. Kitts and Nevis sprinter Tameka Williams became the latest casualty Sunday after admitting to team officials she had used a banned substance and being sent home days before she was due to compete. Earlier Sunday, Uzbekistan's only gymnast at the Games, Luiza Galiulina, was temporarily suspended after her first sample came in positive for the drug Furosemide, often used as a masking agent for other banned substances. Radcliffe out of Olympics Paula Radcliffe's hopes of finally winning an Olympic medal are over, ruined by a foot injury that forced her to withdraw from the Games Sunday. It was the latest setback in a long list of Olympic disappointments for Radcliffe, one of the best female distance runners ever who holds the marathon world record but has failed to win a medal in four previous games. – Agencies
