Pivotal player in potential Bonds indictment remains silent

ESPN.com investigative sports reporter Mike Fish reports on Greg Anderson, the personal trainer whose testimony prosecutors believe could put Barry Bonds behind bars and, in turn, derail his record home run chase. Federal prosecutors "convinced U.S. District Judge William Alsup that Anderson's cooperation is pivotal to their ability to indict [Barry Bonds]. Because Anderson isn't talking despite being subpoenaed to appear before two grand juries, he remains locked up for contempt of court." Anderson will remain behind bars until the grand jury session is scheduled to end in July, unless the U.S Attorney grants a six-month extension.
