egendary Major League Baseball pitcher Roger Clemens was found not guilty Monday of perjury and related charges stemming from accusations that he lied to Congress in 2008, when he testified that he never used performance-enhancing drugs. Had he been convicted on all charges, Clemens faced 15 to 21 months in jail. Former strength and conditioning coach Brian McNamee had testified that he injected Clemens with steroids and human growth hormones in 1998, 2000, and 2001, which Clemens denied in a sworn deposition before the House Committee on Oversight and Government Reform. A mistrial in an original perjury case was declared last summer when prosecutors introduced evidence that the judge had previously ruled inadmissible.
