Barry Bonds tested positive for steroids three times in 2000 and 2001, according to hundreds of documents filed by the US government that were released yesterday.
Prosecutors said a urine test supplied by baseball’s career home run leader also tested positive for performance-enhancing substances in 2003, which was part of an anonymous programme that baseball conducted in 2003.
That information likely will be at the crux of the government’s case against Bonds, who is scheduled to go on trial for perjury charges on March 2.
Bonds is scheduled to be tried on 10 counts of perjury and one count of obstruction of justice related to his BALCO grand jury testimony.
Bonds testified to a federal grand jury in 2003 that he used the “cream” and the “clear” but did not know that they were performance-enhancing drugs.
The urine samples could prove the existence of other steroids in his body.
During testimony, Bonds said he never took steroids but the government alleges that Bonds lied under oath and that at least two of his positive tests stemmed from injections of steroids.
Bonds steadfastly denied during his testimony that he had been injected by his former personal trainer Greg Anderson.
Anderson, who already has served more than a year in jail for his refusal to testify before the BALCO grand jury and repeatedly has refused to testify against Bonds, is alleged to have supplied the former San Francisco Giants star with steroids.
Bonds will be arraigned today.
