Arizona Diamondbacks pitcher Jason Grimsley admitted to federal investigators that he has used illegal performance-enhancing drugs and identified "several other Major League Baseball players by name whom he suspected of using anabolic steroids or human growth hormone," the Arizona Republic reported Wednesday. Federal investigators searched Grimsley?s house Tuesday as part of their investigation of steroid use in baseball. The Arizona Republic also said that Grimsley told investigators that amphetamines are being used "like aspirin," according to a document filed by the top investigator in the steroids scandal in Major League Baseball.
