( CNN ) -- Disgraced American sprinter Justin Gatlin made a successful return to competition on Tuesday following his four-year ban for drug use . The 28-year-old , who won Olympic gold in the 100 meters in 2004 and two world titles the following year , made his comeback at an athletics meet in Eastern Europe . He was the fastest in the 100m heats with a time of 10.34 seconds , qualifying ahead of his compatriots J-Mee Samuels and Rubin Williams at the Kuldliiga meeting in Estonia . Gatlin , who tested positive for excessive levels of testosterone in April 2006 , then triumphed in 10.24 in the final from Samuels ( 10.31 ) and Williams ( 10.54 ) . He had told reporters ahead of the event that he hoped to break the 10-second mark , but was nowhere near threatening his personal best of 9.85 . He will again run on Sunday at an event in the Estonian capital of Tallinn . Gatlin had equaled Asafa Powell 's former world record of 9.77 in May 2006 , but this was later expunged from the books . During his time away from the track , Gatlin spent time working with American NFL teams Tampa Bay Buccaneers , Tennessee Titans and Houston Texans but did not manage to earn a playing contract .
