SAN FRANCISCO Barry Bonds' personal trainer told federal agents he gave steroids to several baseball players, according to documents released Tuesday.
No players were identified in the documents and it was unclear whether the trainer, Greg Anderson, gave specific names to the federal agents.
Anderson was one of four men charged last week in a steroid-distribution ring that allegedly supplied athletes with banned substances. All four pleaded innocent. No athletes have been charged.
Federal officials released two affidavits Tuesday that supported search warrants used in raids on Anderson's home in September.
''Inside Anderson's residence, agents found steroids, syringes and other paraphernalia associated with steroid distribution activities,'' the documents said. ''In addition, agents found files identifying specific athletes. These files contained calendars, which appear to contain references to daily doses of steroids and growth hormones.''
The indictment announced last week said federal agents found about $63,920 in cash in a locked safe at Anderson's residence during the first raid.
''Some of the money was broken up into separate envelopes with the first names of known athlete clients written on them,'' the documents released Tuesday say.
The new documents say Anderson initially denied distributing steroids in discussions with federal agents but later said he sometimes ''gave'' steroids to people he knew.
''Upon further questioning, Anderson admitted that he had given steroids to several professional baseball players,'' the documents say.
Federal agents followed Anderson on Sept. 11, 2002, as he made a quick visit to the Bay Area Laboratory Co-Operative the nutritional supplements lab allegedly at the center of the steroid-distribution ring.
''Anderson returned to his vehicle and proceeded to drive directly, without stopping, to Pacific Bell Park, a professional baseball stadium,'' the documents say. ''Anderson was followed until he entered the players' parking lot area of the professional baseball stadium, past a gate and guarded entrance.''
The Giants played a home day game against the Los Angeles Dodgers on Sept. 11, 2002. Bonds went 2-for-4 with an RBI double, but the Giants lost 7-3.
Anderson was not immediately available for comment. A spokeswoman for Bonds said he would not have any comment Tuesday.
The newly released documents also say BALCO founder Victor Conte admitted giving steroids to Anderson.
''Conte acknowledged that he knew Greg Anderson and stated that he gave Greg Anderson steroids to give to professional baseball players,'' the documents say. ''Conte stated that he knew it was illegal to do this and that he 'assumed' Anderson knew it was illegal.''
Conte and his attorneys were not immediately available for comment.
