The release says drugs, but my sources tell me it was really for letting Deadspin take his drug test for him:
The Office of the Commissioner of Baseball announced today that San Francisco Giants Minor League infielder Marco Guzman has received a 50-game suspension without pay after testing positive for metabolites of Nandrolone, a performance-enhancing substance in violation of the Minor League Drug Prevention and Treatment Program.
Guzman is on the roster of the Dominican summer league Giants. So, no, this doesn’t exactly resonate.
But at least it’s not a Hall of Fame post, right?
