Roger Clemens has filed a defamation suit against Brian McNamee and this is getting really messy. We are finally given a reason why McNamee would lie about injecting Clemens.

The suit, first reported by the Houston Chronicle, states that when McNamee told others that when he first was interviewed by federal law enforcement last June, he denied Clemens had used steroids or human growth hormone. The suit quotes McNamee as saying he was pressured by Assistant U.S. Attorney Matthew Parrella and IRS Special Agent Jeff Novitzky — key members of the BALCO prosecution — to implicate Clemens. The suit did not attribute where the quote from McNamee was obtained.

“After this exchange, and for the first time in his life, McNamee stated that he had injected Clemens with steroids in 1998, 2000 and 2001,” the suit said. “Following his recantation, McNamee has relayed that he magically went from a ‘target’ in a federal criminal drug investigation to a mere ‘witness,’ so long as he continued to ‘toe the line.’ “

What do you all think about Clemens, this news item and his appearance on “60 Minutes” on Sunday?
