Lawyers object to voice mails

SAN FRANCISCO -- Barry Bonds' lawyers in his perjury trial are objecting to the introduction of voice mails the former baseball star left with his girlfriend.

In the voice mails, Bonds sounds irritated because he can't reach Kimberly Bell in most of the 11 messages she collected between 1994 and 2003. Prosecutors want to play the recordings for the jury to bolster their contention that Bonds' short temper was a side effect of steroid use.

Bonds is charged with lying to a grand jury when he said he never knowingly took steroids. His trial starts March 21.

Bonds' lawyers say the recordings don't prove steroid use because they argue cross words naturally occur between lovers. They also argue the recordings will unduly prejudice the jury by casting Bonds in an unflattering light.

The judge hears arguments March 17.
