NEW YORK -- San Francisco Giants infielder Marco Guzman has been suspended for the first 50 games of the season following a positive test under the minor league drug program.
Guzman tested positive for metabolites of Nandrolone, the commissioner's office said Friday.
The 19-year-old hit .254 with nine doubles, one homer and 10 RBIs in 46 games last year for the Dominican Summer League Giants.
There have been five suspensions this year under the minor league program. There were 60 last year along with 16 under the major league program.
