Siobhan Haughey, winner of the 2013 Student of the Year: Sportsperson award, struck silver in the pool on Sunday night to secure Hong Kong's first medal of the Nanjing Youth Olympics.
The 16-year-old swimming prodigy clocked two minutes 13.21 seconds to finish second in the 200m individual medley behind Nguyen Thi Anh Vien of Vietnam.
"I was without my glasses. I couldn't see the screen clearly and it took me a while to find that my little HK red flag ranked second," said Siobhan. "I am really delighted as this is also the first medal for the Hong Kong team."
"My target was to have a personal best time. I realised that goal but did not expect a medal."
The teen star was second after finishing the butterfly leg and dropped to fifth with the backstroke. But she managed to catch up and powered through for second place.
She won a silver medal in the same event at the East Asian Games in Tianjin last year.
Her big achievement came at the world junior swimming championships in Dubai last August when she won gold in the 100m freestyle and bronze in the 50m freestyle. She will compete in those events, as well as the 200m freestyle in Nanjing.
"I won't set medals as my target. All I want to do is to reach the finals and have a personal best time in every event," she said.
