Indians Minor League pitcher Juan Nivar was suspended on Monday after testing positive for a banned steroid.
The Office of the Commissioner of Baseball said Nivar, a right-hander with Cleveland's Rookie-level Dominican Summer League affiliate, 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 immediately.
Nivar, 19, was 4-1 with a 1.36 ERA in 10 starts for the DSL Indians after signing with Cleveland as a free agent last February. He appeared in 10 gamess out of the DSL Tribe's bullpen last season.
Nivar is the 58th player to be suspended for violating the Minor League drug program this year.
