A federal judge in the perjury case against Barry Bonds has decided to allow an audio recording in which, prosecutors say, the retired baseball star's personal trainer discussed his steroids use.
Bonds' lawyers had asked that the recording be excluded from his upcoming trial on charges that he lied to a grand jury when he said he'd never knowingly taken performance-enhancing drugs.
They argued that since the personal trainer, Greg Anderson is refusing to testify there's no way to authenticate the topic of discussion.
But prosecutors plan on calling Bonds' childhood friend and former business partner as a witness.
Stevie Hoskins says he secretly recorded the conversation in March 2003 to convince Bonds' father that his son was taking steroids.
The trial is scheduled to start March 21.
