DAEGU, South Korea -- Usain Bolt won his heat Saturday in 10.10 seconds and qualified for the semifinals in the 100 meters at the world championships.
The world-record holder from Jamaica is looking to defend his 100 and 200 titles in Daegu, South Korea. Two years ago, the Olympic champion set records in winning both events -- just as he did at the 2008 Beijing Games.
Bolt also will be looking for a third gold medal with the Jamaican 4x100 relay team.
Although Bolt said another world record in the 100 is unlikely in Sunday's final, he is expected to easily retain his title because challengers Asafa Powell and Tyson Gay are injured and not competing.
Dodson will compete
U.S. sprinter Jeremy Dodson will attend the world championships after being allowed to travel at a court hearing Friday following his recent arrest on suspicion of identity theft.
Dodson was arrested last week and released on a $10,000 bond. As a condition of his bond, he had to surrender his passport, putting his status for the 200 meters in jeopardy.
Following an advisement hearing in Colorado on Friday, Dodson's agent, Vince Ewing, told The Associated Press in an email that the sprinter had been cleared to leave the country and may arrive as soon as Saturday.
USA Track and Field confirmed he would compete.
