NEW YORK (AP) - Barry Bonds failed a test for amphetamines last season and originally blamed it on a teammate, the Daily News reported Thursday.
When first informed of the positive test, Bonds attributed it to a substance he had taken from teammate Mark Sweeney's locker, the New York City newspaper said, citing several unnamed sources.
Bonds, who always has maintained he never has tested positive for illegal drug use, already is under investigation for lying about steroid use.
A federal grand jury is investigating whether the 42-year-old Bonds perjured himself when he testified in 2003 in the Bay Area Laboratory Co-Operative steroid distribution case that he never knowingly used performance-enhancing drugs. The San Francisco Giants slugger told a 2003 federal grand jury that he believed his trainer Greg Anderson had provided him flaxseed oil and arthritic balm, not steroids.
Under baseball's amphetamines policy, which went into effect last season, players are not publicly identified for a first positive test. A second positive test for amphetamines results in a 25-game suspension. The first failed steroids test costs a player 50 games.
Bonds did not appeal the positive test, according to the Daily News, which made him subject to six drug tests by MLB over the next six months.
