Red Sox Minor Leaguer Miguel "Micky" Pena was suspended for 100 games on Monday after testing positive a third time for a banned substance.
The Office of the Commissioner of Baseball said Pena received a 100-game suspension without pay after a third positive test for a drug of abuse in violation of the Minor League Drug Prevention and Treatment Program. The suspension is effective immediately.
Pena, 23, had previously received a 50-game suspension on April 17, 2013, after his second positive test for a drug of abuse. He returned and split the season between two levels, going 7-8 with a 4.29 ERA in 18 starts between Class A Advanced Salem and Double-A Portland.
The southpaw, Boston's sixth-round pick in 2011, will now miss the remainder of the 2014 season with Portland. He's 2-2 with a 6.41 ERA in 60 1/3 innings over 13 Eastern League starts in his first full season at the Double-A level.
Players are typically issued a warning following a first positive test for a drug of abuse and a 50-game suspension for a second offense. A third violation carries a 100-game ban. Substances considered "drugs of abuse" by Major League Baseball include cocaine, marijuana, heroin, LSD, ecstasy and other opiates. Minor Leaguers who test positive for a performance-enhancing substance are subjected to an immediate 50-game suspension.
Pena is the 29th player to be suspended for violating the Minor League drug program and the fifth to receive a 100-game ban in 2014.
