Scientific tests have linked Roger Clemens’s DNA to blood in syringes that a personal trainer says he used to inject the former star pitcher with performance-enhancing drugs, according to two sources familiar with the investigation.
The DNA results, which are preliminary and subject to verification tests, could prove critical if prosecutors seek an indictment of Clemens on charges that he lied about the use of steroids, according to the sources.
Clemens told the House Oversight and Government Reform Committee last year that he has never taken performance-enhancing drugs. Testifying at the same hearing, the pitcher’s former personal trainer, Brian McNamee, said he injected Clemens nearly 40 times with steroids and human growth hormone from 1998 to 2001.
McNamee’s attorneys have said their client gave federal investigators syringes, gauze pads and other items that he claimed he used to inject Clemens. He stored the items in a FedEx box in his basement.
Clemens and his defense team have long challenged McNamee’s credibility, saying the former trainer has lied about the pitcher’s alleged drug use. They also have said that McNamee may have cooked up the evidence.
