NEW YORK (AP) - Sports Illustrated has reported that Alex Rodriguez tested positive for steroids in 2003.

The magazine says in a story posted on its Web site Saturday that the New York Yankees star tested positive for two anabolic steroids. SI cited four unidentified sources.

SI reports that Rodriguez's name appears on a list of 104 players who tested positive for performance-enhancers in a 2003 baseball survey.

Rodriguez declined to discuss the tests when approached by SI on Thursday at a Miami gym. He told a reporter to speak to the players' union. Calls from SI to union head Donald Fehr were not returned.

Rodriguez played for the Texas Rangers in 2003, when he won the AL home run title and MVP award. He was traded to the Yankees in 2004.
