London, England (Sports Network) - Iran's Ghasem Gholamreza Rezaei and Kim Hyeonwoo of South Korea claimed gold medals in the 96- and 66-kilogram greco- roman wrestling brackets on Tuesday.
Rezaei won at the higher weight, besting Russia's Rustam Totrov. It marked a vast improvement from his 16th-place finish at the 2008 Beijing Games, which came one year after taking bronze at worlds.
Totrov, meanwhile, finished third at the 2011 World Championships but failed to keep the gold in Russia following countryman Aslanbek Khushtov's Beijing win.
Bronze medals in the class went to Swede Jimmy Lindberg and Artur Aleksanyan of Armenia.
Kim, meanwhile, scored a victory over Tamas Lorincz of Hungary to win the 66kg gold. He made his senior debut in 2010 and took a bronze at last year's worlds.
"There is a saying in Korea that my coach uses all the time - 'If you work hard the sky will know.' I worked hard and I think the sky recognized my efforts," said Kim, who fought most of the tournament with an injured eye.
Bronze was claimed by Georgia's Manuchar Tskhadaia and France's Steeve Guenot.
