Giants Minor League third baseman Nathanael Javier received a 50-game suspension on Tuesday after testing positive for a banned steroid.
The Office of the Commissioner of Baseball announced that Javier was suspended without pay after testing positive for metabolites of Stanozolol, a performance-enhancing substance, in violation of the Minor League Drug Prevention and Treatment Program. The suspension will be effective at the start of the 2014 Dominican Summer League season.
Javier, 17, signed with the Giants for $475,000 in July 2012 and batted .229 with two homers, 13 doubles, 28 RBIs, four stolen bases and a .276 on-base percentage in 59 games with the DSL Giants this season.
According to Baseball America, Javier was the Giants' second-most expensive international signing last year. His brother, Sony Javier, appeared in seven games with the DSL Marlins this season.
Stanozolol, commonly sold under the name Winstrol, is a synthetic anabolic steroid derived from testosterone that is sometimes prescribed by veterinarians to encourage muscle growth, red blood cell production, bone density and to stimulate the appetite of weakened animals. It's has been linked to 13 Minor Leaguers in 2013.
Javier is the 54th player suspended this year for violating the Minor League drug program.
