SAN FRANCISCO (AP) — Federal prosecutors say they will prove personal trainer Greg Anderson supplied Barry Bonds with the steroids that led to a positive test in November 2000, the offseason before the slugger hit a major league record 73 home runs.

In a court filing Wednesday, prosecutors provided a glimpse of their trial strategy against Bonds, who's accused of lying to a 2003 grand jury investigating steroids use among elite athletes. Prosecutors said they have two documents showing Bonds tested positive for anabolic steroids in 2000 and that Anderson supplied the drugs, but they did not give details.

Prosecutors made the claim in opposing Bonds' bid to have nine of the 15 felony charges against him tossed out.
