A pair of Cubs prospects were among five players who received 50-game suspensions from Major League Baseball for violations of the league's drug policy.

Erick Castillo, an 18-year-old Venezuelan catcher who had signed with the Cubs in November for $30,000, tested positive for DHEA. Cubs righthander Amalio Reyes, who signed for $8,000 out of the Dominican Republic in November, tested positive for Stanozolol, an anabolic steroid commonly sold as Winstrol.

MLB also announced that three amateur free agents will face 50-game suspensions upon signing, though the league did not elaborate on the players' countries or ages. Pitcher Junior Astacio tested positive for Boldenone, an anabolic steroid, and outfielder Pedro Nunez tested positive for Nandrolone, an anabolic steroid often sold as Deca-Durabolin. Pitcher Tony Feliz also received a 50-game suspension for failing to take a drug test.
