"I ask you to be as merciful as a human being can be,'' said Jones, who cried on her husband's shoulder after she was sentenced.
The disgraced former Olympic champion was ordered to surrender March 11 to begin her term.
U.S. District Judge Kenneth Karas said he gave her the maximum under her plea deal to send a message to athletes who have abused drugs and overlooked the values of "hard work, dedication, teamwork and sportsmanship."
"Athletes in society have an elevated status, they entertain, they inspire, and perhaps, most important, they serve as role models," Karas said.
Later Friday, the judge sentenced Jones' former coach, Olympic champion Steve Riddick, to 5 years and 3 months in prison for his role in the check-fraud scam, less than what the sentencing guidelines recommended. Riddick also was given three years' probation and must pay back $375,000.
The 31-year-old Jones also was given two years' probation and supervised release, during which she will be required to perform 800 hours of community service.
"I respect the judge's order, and I truly hope that people will learn from my mistakes," added Jones.
Talk about showing no mercy towards Marion Jones. I can only imagine what the court will do to Roger Clemens and Barry Bonds where they took steroids in a much more popular sport.
