WASHINGTON (Reuters) - Roger Clemens, one of the best pitchers in baseball history, goes on trial on Wednesday on charges of lying to Congress when he denied taking steroids or other performance-enhancing drugs.
He has pleaded not guilty to the charges -- three counts of making false statements, two counts of perjury and one count of obstructing Congress.
A number of famous sports figures have been convicted in previous prosecutions brought by the U.S. Justice Department. They include:
* Baseball homerun king Barry Bonds was convicted in April by a federal jury in San Francisco on one count of obstruction of justice in an investigation of performance-enhancing drugs in sports.
The jury deadlocked on three other counts accusing Bonds of lying to a federal grand jury. U.S. prosecutors have yet to decide whether to retry Bonds on those charges. Defense lawyers have asked that the one conviction be thrown out or that the charge be retried.
Bonds finished his career in 2007 with 762 home runs, the most in Major League Baseball history. He also set the single-season home run record with 73 in 2001.
* Olympic sprint star Marion Jones received a six-month prison sentence on January 11, 2008, after pleading guilty to lying to federal prosecutors about her steroid use and misleading them about her knowledge of a check fraud case involving her ex-boyfriend, former 100-meters world record holder Tim Montgomery.
Jones, who was stripped of five Olympic medals for using performance-enhancing drugs, was released from prison on September 9, 2008.
* All-Star baseball player Miguel Tejada received a sentence in 2009 of one year of probation and a $5,000 fine for lying to Congress about his knowledge of other players using steroids.
U.S. Magistrate Judge Alan Kay in Washington, D.C., also required that Tejada perform 100 hours of community service. The Dominican Republic native apologized to his fans, Congress and the court after pleading guilty.
He currently plays for the San Francisco Giants.
* Former National Football League player Dana Stubblefield pleaded guilty in 2008 in federal court in San Francisco to lying to a federal agent regarding steroid use.
The defensive lineman and three-time Pro Bowl performer spent seven of his 11 years in the NFL with the San Francisco 49ers before retiring after the 2003 season.
Stubblefield, who cooperated with the federal government's investigation, received a sentence of two years of probation.
