Astros right-hander Yoanys Quiala and a pair of Dominican Summer League pitchers were suspended on Friday after each tested positive for performance-enhancing drugs.
Quiala, Mets righty Jaison Paniagua and the Rangers' Yosiel Serrano were all punished for violating the the Minor League Drug Prevention and Treatment Program -- Quiala was handed an 80-game suspension while Paniagua and Serrano both received 72-game bans.
The Office of the Commissioner of Baseball said Quiala, 24, tested positive for Drostanolone, a banned anabolic steroid that is similar to testosterone. The substance was originally intended to treat breast cancer in women but has since been banned as a performance-enhancer. It's considered a Schedule III controlled substance in the U.S.

Paniagua and Serrano both tested positive for Stanozolol, also a banned steroid. The 20-year-old Paniagua signed with the Mets out of the Dominican Republic on April 5 and has appeared in 4 2/3 innings over five relief appearance for the DSL Mets 2.
