Roger Clemens repeatedly denied using steroids during a conversation with Brian McNamee, but the former trainer would not confirm or deny his assertation. On Monday, Clemens and his lawyer played a tape of a 17-minute conversation between the two as the pitcher continues his defense of allegations in the Mitchell Report that he used performance-enchancing drugs. McNamee told the Mitchell commission that he injected the seven-time Cy Young award winner with steroids and human growth hormone. "For the life of me, I'm trying to figure out why you told guys I did steroids," Clemens says to McNamee on the tape. "I understand that," McNamee responds. Over and over, Clemens makes statements like, "I just want the truth out there and like I said, I can't believe what is being said."
