USAIN BOLT set a new Olympic record time in retaining his 100-meter sprint crown on Sunday in the London Games.

Reigning world champion Yohan Blake made it a 1-2 for Jamaica with a 9.75-second performance.
Justin Gatlin of the United states, winner in the 2004 Athens Summer Games, clocked 9.79 in taking the bronze.
Bolt seeks to complete a sweep of the sprint double when he sees action in the 200 meter dash.
