The government’s only eyewitness to Roger Clemens‘s alleged use of performance enhancing drugs, Brian McNamee, was allowed to name other former teammates of New York Yankees who allegedly used human growth hormone.

Testifying for a sixth day in the perjury trial of Clemens, McNamee, told jurors that he offered HGH to Andy Pettitte and Chuck Knoblauch while helping Mike Stanton to obtain the drug.

“You cannot infer Mr. Clemens is guilty merely because he said other ballplayers used these substances and he provided these substances to them,” Walton told the jury.
