D-backs right-hander Argeny Hiciano was suspended for 50 games Friday after testing positive for a banned steroid.
The Office of the Commissioner of Baseball said Hiciano received a 50-game suspension without pay after testing positive for metabolites of boldenone, a performance-enhancing substance in violation of the Minor League Drug Prevention and Treatment Program. The suspension is effective at the start of Hiciano's season with the Dominican Summer League D-backs in June.
Hiciano, 17, has not yet appeared in a Minor League game. He signed with Arizona as a 16-year-old on Aug. 7, 2013, for $70,000 out of the Dominican Republic and is currently assigned to the D-backs' Rookie-level DSL roster.
Boldenone, more commonly known and marketed as Equipoise, is an anabolic steroid developed for veterinary use, primarily to treat horses. Side effects include increased muscle growth, red blood cell counts and appetite.
Hiciano is the 26th player to be suspended this year for violating the Minor League drug program.
