Right-hander Domingo Acevedo, a three-year major league veteran pitching with Colorado's Triple-A Albuquerque Isotopes, was suspended for 80 games Wednesday for a positive test for the performance-enhancing substance Stanozolol under the minor league drug program. Acevedo, 32, started this season with Piratas de Campeche in Mexico and signed a minor league contract with the Rockies on May 1.
