Usain Bolt and Yohan Blake have both won their semi-final heats in the 200 metres sprint event at the Jamaican National Championships and Olympic trials in Kingston.
Blake, who set a world-leading time of 9.75 seconds in the final of the 100 metres yesterday, was quickest again with a time 19.93 seconds.
Bolt also won his heat, clocking a time of 20.26 seconds, and the pair will meet in the final later today.
Blake is yet to compete in the finals of an Olympics, while Bolt won three gold medals in Beijing four years ago.
