Sir Chris Hoy began his bid to regain the Track Cycling World Championships keirin title with victory in his heat on the final day in Melbourne.
Just one rider was to advance at the first time of asking and Hoy - the 2007, 2008 and 2010 world champion and Olympic champion in Beijing in the event which begins behind a motorised Derny bike - was a comfortable winner of his heat.
Australia's Shane Perkins, who succeeded Hoy as world champion last year in Apeldoorn as the Scot claimed silver, finished fourth in the first of the six heats, won by Yudai Nitta of Japan, and fell into the repechage.
Hoy beat Perkins to sprint bronze on day four at the Hisense Arena.
Jason Kenny, sprint silver medallist behind Gregory Bauge of France on Saturday night after beating Hoy in the semi-final, was second in his heat behind Japan's Kazunari Watanabe to fall into the repechage.
Matt Crampton joined his team-mate after finishing a narrow second to Awang Azizulhasni in his heat, which featured a crash at the final lap bell for Matthew Glaetzer of Australia.
