ESPN reports on Roger Clemens' exclusive interview with "Mike & Mike in the Morning" today.

He maintained his innocence, declaring it "impossible" for his DNA to be linked to the materials that Brian McNamee supplied to the government because he says McNamee never injected him with the drugs alleged. He has provided a DNA sample and has not been summonded to appear in front of a federal grand jury.

He also spoke on the Daily News' new book, "American Icon: The Fall of Roger Clemens and the Rise of Steroids in America's Pastime." He called the excerpts he's read "completely false."

He has only talked with Andy Pettitte a few times following Pettitte's admission to using performance enhancing drugs, though he still considers him a friend.

"I know what your polls say," he said, referring to the general public perception of his guilt. "I've been getting great responses everywhere I've gone in the cities I've traveled to. All I can do is be me and give them the message I just told you about that steroids are bad for these kids. You don't want to have anything to do with them the way they tear your body down."

"But I can't defend a negative. When you've got somebody that's out there that is really just crawling up your back to make a buck, which is what this is, other than speaking out, what else can you do?"
