Japan's Ryusei Kawakami and Taiwan's Chen Min-hsin won the Youth Olympic singles titles in Dakar on Thursday evening, both by four games to two.

Kawakami, the top seed, won the first three games against Colombia's Emanuel Otálvaro, who won the next two before Kawakami closed out the match 11-6. Kawakami, who won the mixed doubles gold with Miku Matsushima on Tuesday, now has two gold medals in Dakar. Otálvaro, 16, had knocked out China's Li Hechen in the quarter-finals.

Chen, 17 and the fifth seed, beat Singapore's 16-year-old Loy Ming Ying, the 10th seed, 4-2. Chen also won the mixed doubles bronze with Lin Chin-ting.

Loy's silver equals Singapore's best Youth Olympic table tennis result, Isabelle Li's runner-up finish at the first Games in Singapore in 2010. "I am happy to be able to fly the Singapore flag," she said, adding that she struggled to return Chen's serve towards the end.
