According to people briefed on the case, drug items that trainer Brian McNamee used to inject Rogers Clemens had performance-enhancing substances on them. McNamee has been claiming that he used syringes, vials and gauze pads to inject Clemens with steroids and human growth hormone in 2000 and 2001. Clemens said McNamee did inject him, but the substances were vitamin B-12 and lidocaine. "I assumed, and I am not surprised, that the tests were positive for both DNA and for performance-enhancing drugs, because that's what Brian said all along, and there's not much doubt that Brian's been telling the truth," McNamee's lawyer, Richard Emery, told The Associated Press. "The confirmation of that fact, once again, just seems to me to be another significant step towards jail for Clemens."
