Former Red Sox pitcher Roger Clemens has vehemently denied ever using steroids despite multiple accusations, and he was found not guilty at his perjury trial in June of 2012.
Clemens' trainer for years, Brian McNamee, testified before a federal grand jury that he had injected Clemens with HGH, along with Pettitte. The seven-time Cy Young winner has been in and out of court for years stating that his longevity in baseball is due to his work ethic rather than any unnatural substance. His lawyer claimed that he wasn't one of the players that tested positive for banned substances in 2003. "He's never injected me with HGH or steroids," Clemens said of McNamee's assertions to baseball investigator George Mitchell.
A first trial on charges he lied to Congress when he testified in 2008 was declared a mistrial.
