(dpa) - Zou Kai took Olympic gold in the men's floor exercise Sunday while in the women's vault, North Korea's Hong Un Jong won after Cheng Fei paid the price for landing on her knees on her second vault.
There were no such worries for Zou, who celebrated a clear win thanks to a score of 16.050 points for his routine with Gervasio Deferr of Spain taking silver with a score of 15.775.
Russia's Anton Golotsutskov claimed bronze after scoring 15.725 while Romania's Marian Dragulescu, Olympic silver medallist in 2004, finished down in seventh place.
China's Cheng looked to be well on her way to gold when scoring 16.075 on her first vault but a score of 15.050 on her second one left the 20-year-old with an average total of 15.562, good enough only for third place and bronze.
Jung took full advantage of Cheng's error, sealing victory with an average points total of 15.650 thanks to scores of 15.550 and 15.750 for her two vaults.
Germany's Uzbekistan-born Oksana Chusovitina, who won Olympic gold with the United Team in 1992 and at the age of 33 was the oldest gymnast in the eight-woman final, took silver with an average 15.575 thanks to vaults of 1.5725 and 15.425.
There was disappointment for Russia's Anna Pavlova who appeared to be well in contention for a medal after an opening vault of 15.625 but she failed to score on her second one, finishing last as a result.
