Career
Born in Jefferson County, Texas, Williams competed at the 2002 United States Junior Championships, taking bronze in the 200 meters and finishing in fourth place in the 100 m. His first major junior tournament was the 2004 World Junior Championships in Athletics. He followed this up with another gold medal in the 4×100 meters relay, setting a junior world record of 38.66 seconds with teammates Omole, Trell Kimmons, and LaShawn Merritt.
Shortly after, Williams broke the 10-second barrier for the first time, running a new 100 m personal best of 9.94 seconds in the quarter-finals of the 2008 United States Olympic Trials.
The time made him the fifth fastest American in the 100 m that year, and ninth in the world rankings. However, he failed to progress beyond the semi-finals: Williams was beaten into fifth place, and out of qualification, by Xavier Carter by just a thousandth of a second.
He ran a personal best of 6.52 seconds in the 60 meters at the 2009 United States of America Indoor Track and Field Championships, reaching the final as the fastest qualifier. However, he was disqualified in the final of the event for a false start.
At the United States of America versus The World relay competition at the Penn Relays, Williams took second place in 38.36 with the United States red team comprising Terrence Trammell, Mark Jelks, and Mike Rodgers.
In May 2009, Williams took part in the 150 meters street race at the Great City Games in Manchester. He finished in third with a time of 15.08 seconds, behind Marlon Devonish and Usain Bolt (who ran a world best 1435 seconds). He reached the final of the United States Championships but finished seventh, missing out on the 2009 World Championships in Athletics.
However, he was barred from competing at the championships after his sample from the United States championships tested positive for Carboxy THC, a marijuana metabolite.
He received a three-month suspension and his championship result was annulled. All information taken from IAAF Profile.
