London Olympics: Brilliant Usain Bolt scorches to sprint gold

LONDON: Usain Bolt achieved his aim of becoming a sporting legend on Sunday as he scorched to the second-fastest 100 metres ever, a superb 9.63 seconds, to become the first man to win back-to-back Olympic sprint titles on the track. 

The Jamaican's 9.58-second run to take the 2009 world title is the only quicker time and Sunday's brilliant display silenced the doubters who predicted his hamstring problems would open the door for his rivals in one of the most eagerly-anticipated races in history. 

World champion Yohan Blake made it a Jamaican 1-2 when he won silver in 9.75 seconds and 2004 Olympic champion Justin Gatlin of the United States grabbed bronze in 9.79 as the first seven men all broke 10 seconds.
