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 too 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 9.58) 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."Johnny Bench Jersey Large .

No one was injured.Lochte, 32, in a statement posted on social media describing the incident, also said he will aim to qualify for the Tokyo Games in 2020.?Lochte and his teammates were returning to the athletes village by taxi after a night out at the French Olympic teams hospitality house in the Rodrigo de Freitas area in the upscale south zone of the city. The outing was several hours after Olympic swimming ended Saturday night at the Rio Games.Their taxi was stopped by individuals posing as armed police officers who demanded the athletes money and other personal belongings, USOC spokesman Patrick Sandusky said in a statement. All four athletes are safe and cooperating with authorities.Sandusky told The Associated Press the robbers took cash and credit cards only, and that no Olympic medals were lost.Traveling with Lochte were Gunnar Bentz, Jack Conger and Jimmy Feigen. Lochte swam in two events at the Rio Games, winning gold in the 4x200-meter freestyle relay. He is a 12-time Olympic medalist.Bentz and Conger were also part of that relay, their only event in Rio. Feigen was on the 4x100-meter freestyle relay, another gold-medal winner for the U.S. in Rio.We got pulled over, in the taxi, and these guys came out with a badge, a police badge, no lights, no nothing -- just a police badge -- and they pulled us over, Lochte told NBCs Today show Sunday. They pulled out their guns, they told the other swimmers to get down on the ground -- they got down on the ground. I refused, I was like we didnt do anything wrong, so -- Im not getting down on the ground.And then the guy pulled out his gun, he cocked it, put it to my forehead and he said, Get down, and I put my hands up, I was like whatever. He took our money, he took my wallet -- he left my cellphone, he left my credentials.USA Today and Fox Sports Australia first reported the news, citing Lochtes mother, Ileana Lochte.Word of the robbery touched off a chain of confusion between Olympic and U.dddddddddddd.S. officials. An International Olympic Committee spokesman said reports of the robbery were absolutely not true, then reversed himself, apologized and said he was relying on initial information from the USOC that was wrong.I couldnt believe it, said Michael Phelps, a good friend of Lochtes and one of his roommates in the athletes village. Phelps spent the evening with his family and wasnt out with his teammates.Brazils sports minister, Leonardo Picciani, said that the swimmers were outside their places of competition and outside the appropriate time. He said no athlete had run into problems at the venues or in the athletes village.We obviously regret that the violence has [gotten] so close to athletes, Rio Games spokesman Mario Andrada said Monday. We?have requested security authorities that they need to make sure everybodys safe everywhere in the city. We apologize to those involved. Once again, we regret that violence is still an issue at these games.Street crime was a major concern of Olympic organizers going into the Games. Brazil deployed 85,000 soldiers and police to secure the Games, twice as many as Britain used during the 2012 London Olympics.Last week, a Brazilian security officer was fatally shot after taking a wrong turn into a dangerous favela, or slum. Two Australian rowing coaches were attacked and robbed by two assailants in Ipanema, and Portugals education minister was held up at knifepoint on a busy street.In addition, stray bullets have twice landed in the equestrian venue, and two windows were shattered on a bus carrying journalists in an attack that Rio organizers blamed on rocks and others claimed was gunfire.American swimmer Nathan Adrian said hes not concerned about his safety.Rio is an amazing city, he said. Theres going to be problems anywhere you go. We have been briefed on how to mitigate those risks as well as possible.Now that swimming is over, Adrian added, the athletes want to see the sights and sounds of Rio.We just came off an amazing performance, he said. All of us are ready to enjoy that a little bit after a long time working really hard.Information from The Associated Press was used in this report.? ' ' '
