The former trainer of Roger Clemens, Brian McNamee, while testifying in a perjury trial involving the pitcher said he understated the alleged use of performance enhancing drugs by the baseball star for protecting the player.

The former trainer said he underplayed the alleged use of anabolic steroids and human growth hormone by Clemens when he first met with agents in June 2007 in New York.

“It was basically to know that Roger knew I wasn’t going to rat him out and had his back … I gave up my whole life to Roger Clemens,” McNamee said when asked why he decided to deceive the agent.
