Augusta GreenJackets pitcher Edward Concepcion has been suspended for violating the Minor League Drug Prevention and Treatment Program, according to a team official.
The right-handed reliever will serve a 25-game suspension starting tonight when the GreenJackets play a double-header in Savannah to start the second half of the regular season.
The 22-year-old Dominican is in his sixth season in the San Francisco Giants minor league system. In his first year of full-season ball, he has posted a 1-1 record and 3.51 ERA in 28 relief appearances for Augusta. He hasn't allowed an earned run in his last eight outings, a stretch of 11 consecutive scoreless innings.
