Dodgers left fielder Manny Ramirez hadn't obtained a therapeutic-use exemption for the drug he took, so he dropped an appeal of his 50-game suspension. Ramirez dropped the appeal within hours of a scheduled hearing last week, after the banned substance turned up in his medical records. The substance -- human chorionic gonadotrophin (HCG) -- is classified as a performance-enhancing substance in baseball's drug policy.
