Ex-Girlfriend, Giambi May Testify Against Barry Bonds

Baseball player Barry Bonds’s former teammate and ex-girlfriend may testify at his March perjury trial that the slugger said he used performance-enhancing drugs, U.S. prosecutors said in a court filing.

A witness list filed today in federal court in San Francisco said the government may call former San Francisco Giant Bobby Estalella, who will testify that Bonds admitted using the substances. Kimberly Bell, Bonds’s ex-girlfriend, will testify that Bonds told her he was taking steroids prior to the 2000 Major League Baseball season and that she observed physical changes in him after 2000, including testicle shrinkage, according to the filing.

Former New York Yankee Jason Giambi will testify that he received performance-enhancing drugs from Bonds’s trainer, Greg Anderson, prosecutors said. Kathy Hoskins, Bonds’s former assistant and personal shopper, will testify that she saw Anderson give Bonds an injection, according to the filing. The potential witnesses are the same ones that prosecutors had planned to call at a March 2009 trial that was postponed.

Bonds, who broke Hank Aaron’s record of 755 career home runs in August 2007, is scheduled to go on trial March 21 on charges of obstruction and lying to a federal grand jury in 2003 when he said he never knowingly took steroids.

Bonds’s attorneys said they may call two trainers to testify about interactions with Bonds, Anderson and other government witnesses, according to a separate court filing. A medical doctor who is an expert on the effects of steroids may also be called to testify for Bonds, according to the filing.

Allen Ruby, Bonds’s attorney, didn’t return a voice-mail message left after regular business hours today.

The case is U.S. v. Bonds, 07-732, U.S. District Court, Northern District of California (San Francisco).
