Nationals first baseman Ryan Zimmerman has been cleared of substance abuse allegations by Major League Baseball, the league announced Friday.
Zimmerman and Phillies first baseman Ryan Howard were named in a Dec. 2015 Al Jazeera report alleging the athletes received Human Growth Hormone (HGH) — a banned substance under the league’s Joint Drug Prevention and Treatment Program — from Charlie Sly.
Sly, a pharmacist, made the allegations on-camera in a documentary called “The Dark Side: Secrets of Sports Doping,” which aired Dec. 27 on the since shuttered cable network Al Jazeera America.
Zimmerman and Howard later filed separate defamation lawsuits against Sly, alleging Sly made false statements when he said both athletes took HGH. The league announced it has completed its investigation into Sly’s allegations, absolving both players of wrongdoing.
“The Office of the Commissioner has completed its investigation into the statements made by Charlie Sly concerning players Ryan Howard of the Philadelphia Phillies and Ryan Zimmerman of the Washington Nationals in the Al Jazeera documentary “The Dark Side.” This thorough investigation did not find any violations of the Joint Drug Prevention and Treatment Program by either Howard or Zimmerman.”
