Experts believe that former Major League pitcher Roger Clemens could be federally indicted for committing perjury when he denied using steroids at the Feb. 13 Mitchell Report hearing, according to The New York Daily News. "The threshold for an indictment is extremely low," said former federal prosecutor Mathew Rosengart. "Prosecutors just need to establish that there is enough evidence to suggest a crime was committed. They just need to establish probable cause." The perjury would be largely based on the testimony of Andy Pettitte and former trainer Brian McNamee. They'd suggest the evidence was tainted," Rosengart said. "They'd ask, 'Why didn't he bring this to Sen. (George) Mitchell?' They'd want jurors to ask why he hung on to old syringes in the first place. The government might think twice about using this."
