The Singapore boys' swim team delivered just two bronzes at the inaugural Asian Youth Games in 2009. But, four years on, they have already won four golds with one more day of competition left.
On Thursday, Quah Zheng Wen and Darren Lim both struck gold in Nanjing, winning the 200-metre individual medley and the 50m freestyle finals respectively.
It marked Zheng Wen's third gold at the AYG in Nanjing. He won the 200m butterfly on Monday and, two days later, took another gold in the 200m backstroke.
The 16-year-old also clinched silvers in the boys' 200m freestyle and the 4x100m freestyle relay on Tuesday and, together with team-mates Christopher Cheong, Jerryl Yong and Darren, added another bronze last night in the 4x100m medley relay.
For 14-year-old Darren, his moment of glory came when he touched home in 23.09 seconds, 0.37sec faster than Malaysia's Lim Ching Hwang. South Korea's Kim Da San finished third, 0.01sec behind Ching Hwang.
However, Darren was unable to break Ang Peng Siong's national record of 22.69 set in 1982 - which was also a world record at that time.
Ang's elusive mark remains the oldest national record across all age groups in the sport in Singapore.
Darren told The Straits Times: "I'm really happy to win the gold medal but am a bit disappointed as this wasn't my personal best and I missed out on the record again."
