Double-A pitcher Pena suspended

BOSTON -- Major League Baseball announced Monday that Boston Red Sox minor league pitcher Miguel Pena has been suspended 100 games without pay after a third positive test for a drug of abuse. The suspension is effective immediately.

MLB’s joint drug prevention and treatment program distinguishes between performance-enhancing drugs and drugs of abuse, which include marijuana, cocaine, LSD and opiates.

Pena, a 23-year-old left-hander currently pitching for Double-A Portland, was 2-2 with a 6.41 ERA in 13 starts this season. He was drafted in the sixth round of the 2011 MLB draft.

The suspension is Pena’s second in two years as he was suspended 50 games in April 2013 following a second positive test for a drug of abuse.
