KINGSTON - Jamaican Olympic champion Usain Bolt held his nerve after two false starts by competitors and powered to the year's fastest 100 metres at the Jamaica International Invitational on Saturday.

The 100 and 200 metres world record holder clocked a dazzling 9.82 seconds in his first individual race of 2012, exploding from the blocks to take control at 40 metres.

"It's a good start, I would say," said Bolt, who erased the previous season-leading time of 9.90 by his training partner and world champion Yohan Blake three weeks ago.

"I feel better than last year, so I'm definitely happy with myself," Bolt added.

"I don't think my execution was perfect, but I think for my first race it was good."  

Michael Frater, a member of Jamaica's world record 4x100 metres relay team, finished a distant second in exactly 10 seconds.

Bolt was disqualified from last year's 100 final at the world championships because of a false start, but was not perturbed by the delays.

"A couple of false starts will throw you off, but I stayed focused and went out there and executed as best as possible, so I'm just happy with myself," he said.

Although pleased with the last 50 metres of the race, the lanky sprinter, who owns world records of 9.58 seconds in the 100 and 19.19 in the 200, said he must continue to work on the first phase of the shorter race.

"I always try to work on my first 40 metres because the last 40 metres is always the best part of my race," he said. "So over the season as I get more fit and get more fluent it will definitely get better."

Women's world champion Carmelita Jeter was also impressive in the 100.

The American sped to a season-leading 10.81 ahead of Kelly-Ann Baptiste of Trinidad and Tobago, who finished in 10.86. Jamaican Olympic silver medallist Kerron Stewart was third in 10.98.

"I feel good with that win and I'm injury free," Jeter said. "I know there's some things I didn't do right and I'm sure my coach is going to get on me, but it's a long season.

"Right now I just have to stay healthy ... to stay humble, stay focused ... I can't get ahead of myself, I can't get big-headed because you never know who is going to show up."

Jamaican Brigitte Foster Hilton, the 2009 world champion who struggled in 2011, appeared to have regained her form in the 100 hurdles, winning in 12.51 seconds.

The time was just 0.02 behind the world leading performance of 12.49 by current world champion Sally Pearson of Australia.
