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

In a court filing Wednesday, prosecutors say they have two documents showing Bonds tested positive for anabolic steroids in 2000 and that Anderson supplied the drugs.

Bonds has pleaded not guilty to 14 counts of making false declarations to a grand jury and one count of obstruction of justice.
