Former Red Sox great Roger Clemens, his legacy as imperiled as baseball’s integrity by the steroid scandal, was indicted yesterday on multiple charges of lying to Congress when he denied plying himself with illegal performance-enhancing drugs.

Baseball’s all-time leader with seven Cy Young Awards, William Roger Clemens was charged by a federal grand jury with one count of obstruction of Congress, three counts of making false statements, and two counts of perjury stemming from his sworn testimony in 2008 before a House committee investigating baseball’s steroid era.

Under federal sentencing guidelines, Clemens, 48, could face 15 to 21 months in prison if convicted. The maximum sentence would be 30 years and a $1.5 million fine.
