Incheon - Qatar's Femi Ogunode won the Asian Games 100 metres gold in a new continental record time of 9.93 seconds despite wet conditions on Sunday.
Nigeria-born Ogunode, who won the 200-400m double at the 2010 Asiad, beat China's Su Bingtan, with Japan's Kei Takase third.
Hopes for an Asia-born athlete finally breaking the 10s barrier sank with Su crossing in 10.10 and his Chinese team-mate Zhang Peimeng timing 10.18 in fourth.
Ogunode's win is Qatar's second athletics gold of the tournament, pulling them level in their shootout with fellow wealthy Gulf state Bahrain.
His time bettered the 9.99 that teammate Samuel Francis ran at the Asian Championships in 2007. Francis, visibly struggling with a leg injury, finished last.
