Bonds' ex-trainer back in jail

A former trainer of San Francisco Giants outfielder Barry Bonds returned to jail for failing to fully testify before a grand jury investigating steroid use.

Greg Anderson, 40, was charged Monday by U.S. District Judge William Alsup with contempt of court and may remain jailed until he changes his mind or the grand jury's term expires in about 16 months.

"Sometimes, sitting in the cooler for a long time may have a therapeutic effect, and may change his mind," Alsup said. "Maybe in 16 months he will change his mind."

Anderson, who has refused to testify five times, spent 15 days in a Dublin, Calif., jail last month, only to be released July 20 when that grand jury's term expired.

Earlier, he was ordered to serve a three-month prison term and three months of home detention upon pleading guilty to steroid distribution and money laundering stemming from the U.S. government's investigation into the Bay Area Laboratory Co-operative (BALCO).

Attorney Mark Geragos argued Monday that Anderson refuses to testify because it would be a violation of the terms of the plea bargain, which state that he wouldn't co-operate with the government.

Alsup rejected the lawyer's argument, telling Geragos that returning Anderson to jail might test "how loyal your client wants to be."

BALCO president and founder Victor Conte, vice-president James Valente and Anderson were convicted last Oct. 15 of operating an illegal steroid distribution ring.

BALCO allegedly supplied steroids to elite athletes, including Bonds, Jason Giambi of the New York Yankees, former NFLer Bill Romanowski and sprinters Tim Montgomery and Marion Jones.

The name of Gary Sheffield, another Yankee slugger, also came up during Monday's hearing as Alsup recited questions that went unanswered by Anderson.

According to court documents, federal authorities wanted Anderson to testify about doping calendars obtained at his home. The charts allegedly have Bonds' name on them.

Bonds testified that he did not "knowingly" take performance-enhancing drugs and that Anderson provided him with flaxseed oil and arthritic balm.

Authorities suspect that Bonds lied under oath. He is being investigated for perjury and tax evasion.
