The Associated Press reports that former Major League right-handed pitcher Roger Clemens has entered a not guilty plea Monday to charges of lying to Congress about whether he used steroids or human growth hormones.

If convicted, Clemens could face up to 30 years in prison and a $1.5 million fine in addition to damages to his reputation, future earning potential and chances of getting into the Baseball Hall of Fame.

In 24 seasons with the Boston Red Sox, Toronto Blue Jays, New York Yankees and Houston Astros, Clemens was 354-184 with a 3.12 ERA.
