Barry Bonds, the all-time home run leader whose connection to performance enhancing drugs has kept him out of the Hall of Fame, had his conviction on obstruction of justice upheld by a federal appeals court on Friday and will begin serving his sentence immediately, according to the Associated Press.

The conviction came after a 2003 hearing before a grand jury looking into the Bay Area Laboratory Co-Operative, commonly referred to as BALCO, and the role the lab played in distributing steroids and other performance enhancers to elite athletes. During the hearing it was ruled that Bonds' testimony was evasive and intended to hinder the investigation, the Associated Press reports.

"Meanwhile, I also intend to seek further judicial review of the important legal issues presented by the appeal that was decided today," Bonds said in a statement. "This has been a long and difficult chapter in my life and I look forward to moving beyond it once I have fulfilled the penalties ordered by the court."

Bonds was sentenced to 30 days of house arrest and two years of probation. In addition to those penalties Bonds is also ordered to serve 250 hours of community service working with youths, according to the Los Angeles Times.

The obstruction of justice charge came from one specific answer during the hearing. Bonds had been asked by the prosecution if Greg Anderson, Bonds' personal trainer, had every given him something that he could inject himself with. Bonds went on to give a long, rambling answer that went on tangents about growing up the child of a celebrity, fishing and friendship before eventually answering no, according to the Los Angeles Times.

"When factually true statements are misleading or evasive, they can prevent the grand jury from obtaining truthful and responsive answers," Judge Mary Schroeder said. "They may therefore obstruct and impede the administration of justice."

Bonds still has the option to have the same panel reconsider his case for a second time or to petition the U.S. Supreme Court to hear his appeal, according to the Associated Press.
