Lab workers take stand at Bonds trial

- Associated Press - Tuesday, April 5, 2011

SAN FRANCISCO (AP) - Prosecutors began day 10 of the Barry Bonds perjury trial trying to close the loop on the slugger's 2003 urine sample that tested positive for steroids.

Prosecutors on Tuesday morning called three chemists from the UCLA Olympic Analytical Laboratory to discuss how they handled and tested the sample.

Bonds provided the sample in 2003 as part of Major League Baseball's initial steroids testing program. Federal investigators seized the sample in 2004 and had the UCLA lab test it in 2006.

The former head of the lab, Dr. Don Catlin, is expected to testify next.

Bonds is on trial for allegedly lying to a grand jury when he denied knowingly taking steroids. The trial is in its third week.
