bar gold medallist Zou Kai and teenager Sui Lu led one-two finishes for China in individual events at the World Gymnastics Championships Sunday. China finished top of the table, as it did last year, with 12 medals including four golds. The United States also grabbed four golds, with a total medal haul of seven. Host Japan won two titles and seven medals in all.Zou, 23, regained the world horizontal bar title, which he lost in his absence last year, by narrowly beating defending champion and teammate Zhang Chenglong by 16.441 to 16.366. Japan's Kohei Uchimura, who in the past two days won an unprecedented third straight all-around title as well as the floor exercise, finished third on 16.333 to lift what he called an “unexpected” medal. Sui, 19, who already has the 2009 world floor exercise bronze in her medal collection, scored 15.866 points on the balance beam to lift her first world title. Her teammate Yao Jinnan finished second on 15.233 and American Jordyn Wieber, who won the women's all-around title, third on 15.133. On the floor exercise, Sui yielded the gold by 0.067 points to Russia's Kseniia Afanaseva who won with 15.133. Zou finished runner-up to Uchimura on the floor on Saturday when China's Olympic rings gold medallist Chen Yibing won his fourth world championship title on his trademark apparatus. The Chinese men, who won a fifth straight world team title in Tokyo adding to their 2008 Olympic gold, featured Olympic and world champions, but lacked solid all-arounders like Uchimura. Sui, who combined with Yao and other teammates to finish third behind the United States and Russia in the women's team final, admitted of her beam performance: “I was so tense during my routine that I almost lost my head. In other events, US national champion Danell Leyva won the parallel bars. Yang Hak-Seon won the men's vault title to become South Korea's fourth world champion and the first since 2007, when Kim Dae-Eun won the men's parallel bars.
