Superstar sprinter Usain Bolt has eased into the 100 metres semi-finals at the London Olympics showing no signs of the hamstring injury which hampered him at the Jamaican trials.

The world record holder and reigning Olympic champion stumbled at the start of his heat but recovered to win it, easing up in 10.09 seconds.

Several runners ran faster times, with two Americans - Justin Gatlin and Ryan Bailey - setting early markers by going under ten seconds.

Bolt told reporters after the race that his legs were feeling good and he was happy, Reuters reports.

"My reaction was good but I made a bad step and I stumbled a little. But overall it was good."

Bailey was the quickest qualifier with his blistering run of 9.88 seconds to match his personal best.

Gatlin, who has served a four-year doping ban since winning the title at the Athens Games, had just set the standard with his run of 9.97 in the second heat.

The semi-finals will be raced on Sunday.
