The former San Francisco Giants star has long faced speculation about whether he took drugs to boost his performance.
In 2007 he was indicted on a number of charges for allegedly lying to a grand jury during the government's investigation of a drug company. During the hearings he testified that he never knowingly took any illegal steroids.
Bonds' trial began in San Francisco, California in March (11) and on Wednesday (13Apr11) he was convicted of obstruction of justice.
The jury was unable to reach a decision on a number of perjury charges. He now faces up to 21 months in prison.
Bonds, the son of baseball player Bobby Bonds, broke numerous records during his stellar sports career, hitting an all-time high of 762 home runs in Major League Baseball and holding the record for most home runs in a season, having reached 73 in 2001.
