Estalella was a teammate of Bonds' on the Giants during the 2000 and 2001 seasons.
In his leaked testimony during the BALCO investigation, Estalella admitted to a grand jury that he had used the "cream," the "clear" and human growth hormone that was provided to him by Greg Anderson, Bonds' personal trainer.
Estalella also was named in the December 2007 Mitchell report on the use of performance-enhancing drugs in baseball, in connection with an assessment by the Los Angeles Dodgers of his value as a free agent in late October 2003. According to the Mitchell report, Ellen Harrigan, an administrator in the Dodgers' scouting department, recorded an observation by one of the participants in a meeting discussing Estalella that he was a "poster boy for the chemicals."
Bonds testified in front of the BALCO grand jury in 2003 that he used the "cream" and the "clear," but didn't know they were performance-enhancing drugs. The government alleges he lied under oath, leading to the March 2 perjury trial date.
The government also has subpoenaed Anderson to testify at the trial, but Anderson's attorney, Mark Geragos, has told ESPN that Anderson will not appear or testify.
Estalella, one of several of Bonds' former teammates expected to be subpoenaed for the trial, played for six teams during his nine-year major-league career from 1996 to 2004.
