FILE - This June 5, 2012 file photo shows San Francisco Giants' Melky Cabrera reacting after striking out during the first inning of a baseball game against the San Diego Padres in San Diego. Cabrera has been suspended for 50 games without pay after testing positive for testosterone. The commissioner's office says the suspension is effective immediately. Major League Baseball said on Wednesday, Aug. 15, 2012, that Cabrera tested positive for the banned performance-enhancing substance, which violates MLB's joint drug prevention and treatment program.
