On February 7, 2009, "Sports Illustrated" reported that Rodriguez tested positive for testosterone and the anabolic steroid Primobolan in 2003. Rodriguez's name appears on a government-sealed list of 104 major-league players (out of 1200 tested) who came up positive for performance-enhancing drugs. The report was compiled as part of Major League Baseball's 2003 survey to see whether mandatory random drug testing program might be necessary. At the time, there was no penalty or punishment for a positive steroid test. Rodriguez did not immediately confirm the allegations, deferring at first to the players' union. Two days after the allegations, Rodriguez admitted to steroid use from 2001 until 2003, claiming that he ceased using such substances after spring training that year.
