LONDON (Reuters) - Zou Kai won his showdown with Japan's all-around champion Kohei Uchimura to give China a second gymnastics gold medal at the London Olympics when he tumbled to glory in the men's floor exercise final on Sunday.

Zou's gravity-defying tumbles and balancing strength maneuvers allowed him to become only the second man, after the Soviet Union's Nikolai Andrianov in the 1970s, to win successive Games titles on the apparatus with a score of 15.933.

Uchimura had the same 15.800 score as Russia's Denis Ablyazin but was awarded the silver on the tiebreak rule.

The result meant Uchimura will leave London with one gold and two silvers as he did not qualify for any other apparatus final.

Ablyazin, who scraped into the final thanks to the tiebreak rule after three gymnasts finished with the same score in qualifying, leapt into the arms of his coach when he realized he had secured the bronze.
