Major League Baseball has found no evidence of PED use by Phillies first baseman Ryan Howard or Nationals first baseman Ryan Zimmerman after the two players were implicated in an Al Jazeera documentary on doping in sports.
"[MLB] did not find any violations of the Joint Drug Prevention and Treatment Program by either Howard or Zimmerman," the league said in a statement on Friday, according to the Associated Press.
An investigative report Al Jazeera released in December alleged that Zimmerman and Howard bought and used the drug Delta-2, a hormone supplement, and human growth hormone from an Indianapolis anti-aging clinic.
