Two Minor League players suspended

MESA, Ariz. -- Cubs Minor League pitcher Ricardo Estevez received a 50-game suspension after testing positive for taking two substances that are in violation of the Minor League drug prevention and treatment program.

The Office of the Commissioner of Baseball announced the suspension on Friday.

Estevez, a right-handed pitcher, tested positive for metabolites of Stanozolol and Nandrolone. A member of the Dominican Summer League Cubs, his suspension will be effective at the start of this season.

Free agent Minor League left-handed pitcher Jorge Navarrete also received a 50-game suspension after refusing to take a drug test. The suspension of Navarrete is effective immediately upon his signing with a Major League organization.
