San Francisco, CA (Sports Network) - A recording discovered by a key witness in the perjury trial of Barry Bonds was disallowed by the judge on Tuesday.

U.S. District judge Susan Illston said the recording between Steve Hoskins and Dr. Arthur Ting was mostly inaudible and therefore irrelevant and inadmissible as evidence.

The prosecution hoped the recording would back Hoskins' testimony after Ting contradicted him by saying the pair never discussed Bonds' use of steroids.

Instead, the prosecution read a transcript of Bonds' 2003 grand jury testimony.

It also called four lab employees to testify on the findings of urine samples collected from Bonds in 2003. One of them tested positive for the designer steroid THG, also known as "the clear."

After 25 witnesses and 2 1/2 weeks, the prosecution rested its case and the defense begins its arguments on Wednesday.

The defense's presentation could include Bonds himself as one of six witnesses on the stand. If all goes according to plan, closing arguments would begin on Thursday morning and the trial would then be in the hands of the jury.

Bonds is accused of four counts to lying to a grand jury that he knowingly took steroids and one count of obstruction of justice.
