Yang Hak-Seon won the men's vault title on Sunday to take South Korea's first medal of the 2011 world gymnastics championships in Tokyo. He scored the event's highest mark of 16.866 points in his first vault and followed up with 16.266 in the second for an average 16.566, to earn South Korea's first world gold since 2007, when Kim Dae-Eun won the men's parallel bars. Russia's Anton Golotsutskov scored an average 16.366 to grab a second successive silver and Makoto Okiguchi finished third on 16.291. Yang, 19, was fourth at last year's championships in Rotterdam.
