TALLINN, Estonia -- Justin Gatlin has won his second race in a week at the Ergo Games in Tallinn, Estonia, during his low-key return to track after a four-year doping ban.

The 28-year-old former Olympic champion finished the 100 meters in 10.17 seconds, beating fellow American Justin Williams by 0.08 seconds at the small meet in the Estonian capital Sunday. Aleksandr Linnik of Belarus was third in 10.59.

Gatlin got off to a sluggish start, but his acceleration at the halfway point helped him to pull away from the rest of the field and finish the race comfortably in first place.

The sprinter made his comeback at a small meet in the northeastern Estonian town of Rakvere on Tuesday, winning in 10.24.
