KINGSTON, Jamaica -- Usain Bolt is revving up for the world championships in August, but he says he has a lot or work on before the Moscow meet. The worlds fastest man clocked a 9.94 seconds in the 100 metres to win the finals of the Jamaica national championships on Friday night. But he sounded less than thrilled with his performance. "Its all about getting through and getting it done and thats what I did," Bolt told reporters after the race in the islands national stadium, which was half empty on a calm Friday night in Kingston. He said his start and his "execution wasnt the best" but he was "feeling all right, not t tired." He said he was fairly pleased with his acceleration - or his "turbo," as he calls it - but its not yet where he wants it to be. "Ive got a lot more work to do," the 100 and 200 world record-holder said after the race, adding, "As long as the coach is not worried, Im not worried." Behind Bolt was Kemar Bailey-Cole at 9.98 and Nickel Ashmeade at 9.99. Former world record holder Asafa Powell did not finish in the top three to qualify for the worlds, shocking some of the decorated sprint stars many fans in Jamaica. At Fridays 100 metre finals, Bolts night was certainly made easier by the absence of teammate Yohan Blake. The Olympic silver medallist withdrew from the meet because of a hamstring injury that his agent says hasnt completely healed. But since Blake won the 100 metres at the 2011 worlds he has automatic qualification for the race at the August competition in Moscow. Bolt has dominated global sprinting for years. The powerful Jamaican has set world records (his mark stands at 9.5 and captured two straight Olympic 100-meter finals. But earlier this month at the Golden Gala meet in Rome, Bolt lost by a hundredth of a second to American Justin Gatlin in the 100. It was Bolts first significant loss since his false-start disqualification at the 2011 world championships in South Korean. At the U.S. championships in Iowa on Friday night, American sprinter Tyson Gay overcame a slow start to win the 100 metres, surging past Gatlin halfway through the race. Gay finished in a time of 9.75 seconds, the fastest in the world this season. At Jamaicas meet on Friday, Kerron Stewart won the womens 100 metres. She ran 10.94 seconds, beating Sherone Simpson and Schillonie Calvert. Two-time Olympic champion Shelley-Anne Fraser-Pryce qualified for the worlds after dominating the Diamond League. Decorated female sprinter Veronica Campbell-Brown is also missing Jamaicas national championships due to a positive drug test being investigated by an island anti-doping panel. Three-time Olympic gold medallist Campbell-Brown, or "VCB," as she known in sprinting circles, tested positive for a banned substance at a meet in May and will serve a suspension while anti-doping officials rules on the positive drug test. Earlier this week, Campbell-Browns manager, Claude Bryan, said the accusation came as a "shock to her" and the reigning 200-meter world champ is determined to clear her name. Just before Fridays meet got under way, Warren Blake, president of the Jamaica Athletics Administrative Association, urged people not to rush to judgment, saying everyone should wait for the official ruling from the disciplinary panel. A day after Jamaican officials announced Campbell-Browns provisional suspension, a spokesman for the International Association of Athletics Federations told AP that "all evidence seems to point to this offence being a lesser one."
