New York Yankees’ Alex Rodriguez tested positive to steroids in 2003, according to a report from Sports Illustrated.
Rodriguez, perhaps the most successful player in the history of baseball, holding a range of records including most home runs, refused to answer questions about the allegation.
SI claims that Rodriguez is on a list of positive results obtained in 2003 under an agreement that no results or player names would be released as part of an assessment into how widespread steroids were in the sport.
If at least 5% of the tests were positive, however, baseball would institute random testing, with players testing positive publicly identified and suspended. Of 1,198 players tested, 104 came back positive.
The list of names is subject to a court battle, after the US government seized the test results as part of the BALCO investigation.
