The US sprinter Justin Gatlin has clocked 10.17 seconds to win his second consecutive 100 metres final since coming back from a four-year doping ban.
Gatlin, the 2004 Olympic 100 metres champion, was running at the Ergo World challenge meeting in Tallinn as he works towards the London 2012 Olympic Games.
Before August 3rd, when he also ran in Estonia, he had not raced competitively since June 2006 after being banned because of a positive test for the male sex hormone testosterone and its precursors.
Gatin bettered his final time from the August the 3rd meeting where he ran 10.24 seconds.
His personal best is 9.85.
Fellow American Rubin Williams was second on Sunday in 10.25.
