Bolt hasn't lost since failing to defend his gold at the 2011 Dague world championships after being disqualified in the final for a false start.

Lerone Clarke was next in 10.10, completing a 1-2-3 sweep for Jamaica.

"When I came out from the blocks, I reacted good. But the execution, because I wasn't as comfortable as I wanted to be, wasn't that good during the first 30 meters," Bolt said. "Asafa got into his running form way quicker than me and got the top speed, while I had to work a little harder to get into my stride. But the good thing is I still got it. I ran past him, so I'm happy."

"I have run world records where my coach has said the race wasn't perfect," he added.

Bolt's 9.79 is his third fastest time of the season.

Powell, whose only win over Bolt came in 2008 in Stockholm, kept positive after the race.

"Tonight, I proved that I have it in me," said Powell. "I did my own thing. Normally, people say I can't perform under pressure. I think I performed under pressure tonight. I knew if I ran like I was supposed to, that it was going to be close. I was either going to win or it was going to be close.

"I am satisfied. I still have a long way to go (to the Olympics). You never know. You might see another result at the Olympics."
