The suspension makes Ramirez the biggest star penalized under baseball's testing program that started in 2003.
Manny Ramirez has tested positive for performance-enhancing drugs and will be suspended 50 games starting today, The Times has learned.
The test result and suspension is expected to be announced later today. The Dodgers informed triple-A outfielder Xavier Paul this morning that he was being promoted to Los Angeles.
Ramirez is expected to attribute the test results to medication received from a doctor for a personal medical issue, according to a source familiar with matter but not authorized to speak publicly.
With the suspension taking effect with tonight's game at Dodger Stadium, Ramirez will not be eligible to return to the team until July 3.
Ramirez would become the biggest star suspended under an oft-criticized major league testing program that started in 2003. He had been a model citizen since arriving in Los Angeles last August, following a stormy tenure with the Boston Red Sox.
This is the second drug scandal to rock baseball within four months. In a year in which baseball officials hoped their greatest concern would be the slumping economy, the two highest-paid players in the game have been revealed to have failed a drug test.
Alex Rodriguez, the game's highest-paid player, acknowledged during a February news conference that he used steroids from 2001 to 2003. The admission followed a Sports Illustrated report that he failed a drug test in 2003, when players were not subject to suspension.
