Prosecution witness Brian McNamee names 3 other players he says took HGH in Roger Clemens trial WASHINGTON - The key witness in the Roger Clemens perjury trial testified Monday about three other baseball players who he said took human growth hormone. Brian McNamee, Clemens' longtime strength and conditioning coach, told jurors that he provided HGH to current Yankee pitcher Andy Pettitte and former Yankee infielder Chuck Knoblauch. McNamee also testified that former Yankee pitcher Mike Stanton obtained HGH from drug dealer Kirk Radomski, after McNamee put them in touch. McNamee hadn't been allowed to name the players before, but U.S. District Judge Reggie Walton said Monday he would allow it to rebut the suggestion made by Clemens' lawyer during cross-examination that McNamee solely targeted the former pitcher. Both Pettitte and Knoblauch told congressional investigators in 2008 that McNamee injected them with HGH. Clemens, a seven-time Cy Young Award winner, denied McNamee's accusations to Congress that year, and he's on trial for allegedly lying to Congress in making those denials. Prosecutors, who hope the information about the three players will help rehabilitate McNamee's credibility, finished their redirect questioning of McNamee on Monday. The trial is now in its sixth week.
