Major League Baseball has suspended Nationals minor league catcher Michael Albaladejo, who was playing for the organization’s Gulf Coast League affiliate, for 50 games for testing positive for the banned stimulant Methylhexaneamine.

Albaladejo, 22, played baseball at Florida Atlantic before signing a free agent contract with the Nationals in early July. In 17 games for the GCL team, Albaladejo was hitting .234 (11 for 47) with four runs batted in.

This isn’t the first Nationals minor leaguer suspended or disciplined for violating the league’s drug policy.

In June, Class AAA Syracuse reliever and George Washington alum Josh Wilkie was suspended 50 games for doing so. At the same time, Class AA Harrisburg reliever Rafael Martin and Syracuse infielder Josh Johnson entered MLB’s drug treatment program as first-time offenders for a drug of abuse, not a performance-enhancer.
