The commissioner's office announced two drug suspensions late Friday afternoon, only one of them affecting a player currently under contract.

Giants minor league righthander Edward Concepcion received a 25-game suspension for a "violation of the drug-testing program," according to a press release. The 22-year-old native of the Dominican Republic appeared in 28 games for low Class A Augusta this season, his sixth in professional ball. With the Greenjackets, Concepcion went 1-1, 3.51 while collecting 36 strikeouts and 24 walks in 33 1/3.

Righthander Andy Moss, whom the Cardinals released in May, received a 50-game suspension after testing positive for a metabolite of Drostanolone, according to the release. A St. Louis 35th-round pick in 2009, Moss went 1-2, 1.32 in 13 appearances for Rookie-level Johnson City that summer to win the Appalachian League's ERA title. Pitching for low Class A Quad Cities this season, the 24-year-old went 2-0, 5.79 in six relief appearances.
