Former Olympic champion Justin Gatlin claimed victory on Tuesday in his first competitive race following a four-year doping ban.

The American sprinter, who comfortably won his 100metres heat earlier in the day, finished with a time of 10.24 seconds to triumph in the final at the Kuldliiga meet in Estonia.

That was an improvement of 0.10secs on the 28-year-old's time in his heat, but some way off his personal best of 9.85.

Compatriots J-Mee Samuels and Rubin Williams were 0.07 and 0.30secs further back respectively.

Gatlin, who won gold in the 100m at the 2004 Athens Olympics as well as triumphing in the 100m and 200m at the 2005 World Championships, was banned in 2006 after testing positive for excessive testosterone.
