Federal prosecutors plan to call Barry Bonds' former personal shopper to testify at his trial next month that she saw the former Major League Baseball star's personal trainer inject him. Prosecutors also said in a court filing on Friday that former teammate Bobby Estalella will testify Bonds told him about using performance-enhancing drugs. Bonds' former personal shopper, Kathy Hoskins, is the sister of the MLB home run king's former business partner, Steve Hoskins. She is expected to testify she saw personal trainer Greg Anderson inject the San Francisco Giants slugger. The filing did not say whether she believed the syringe contained steroids. Bonds has pleaded not guilty to charges that he lied in 2003 to a grand jury when he said he never knowingly used steroids. Prosecutors said they plan to call Jason Giambi of the Oakland Athletics, his retired brother, Jeremy, and five other former players: Benito Santiago, Armando Rios, Randy Velarde, Marvin Benard and Estalella. Prosecutors also said they intend to call former Bonds girlfriend Kimberly Bell and Anderson to the witness stand at Bonds' trial, scheduled to begin on March 2. In several court filings on Friday, prosecutors said they plan to have Anderson jailed again if he refuses to testify at the trial. Anderson's attorney has said the trainer will refuse to testify. Anderson already has spent more than a year in prison for refusing to testify in front of a federal grand jury investigating Bonds. A judge could jail Anderson for the duration of the trial, which is expected to last about a month. Also on Friday, Bonds lawyers said in a court filing they may introduce the 2006 grand jury testimony of Giants general manager Brian Sabean and interviews former San Francisco 49ers Jerry Rice and Terrell Owens gave to investigators in June 2003. Sabean testified in 2006 before the grand jury investigating Bonds, and the two NFL wide receivers had connections to Steve Hoskins, who is expected to testify against Bonds at trial.
