Philadelphia’s Ryan Howard and Washington’s Ryan Zimmerman have been cleared by Major League Baseball of allegations they used banned performance-enhancing substances.

Pharmacist Charlie Sly claimed in an Al-Jazeera America documentary “The Dark Side: Secrets of Sports Doping,” which was broadcast Dec. 27, that the two used banned performance-enhancing substances.

In a brief statement Friday, MLB said its investigation “did not find any violations of the Joint Drug Prevention and Treatment Program by either Howard or Zimmerman.”
