Australian Patrick Constable has scored the biggest win of his cycling career, taking out the sprint in the last round of the track World Cup.
Australia won two gold medals and a silver in the Hong Kong event, with a young men's team pursuit squad impressing and Stephanie Morton taking second in the keirin.
Constable claimed a big scalp in his semi-final, beating British Olympic gold medallist Jason Kenny two heats to nil.
The Adelaide rider then also dispatched China's Chao Xu 2-0 in the gold medal ride-off.
Constable had only qualified 12th-fastest and also had to come from one heat down to beat Russian Nikita Shurshin.
