Marlins closer Leo Nunez has admitted to using fake documents and a fake ID to sign a professional contract more than a year ago. Central Electoral Commission President Roberto Rosario said at a news conference that Nunez signed a sworn statement in the Dominican Republic saying he is not the person identified in official documents. Nunez returned to his native Dominican Republic on Thursday amid accusations that he was playing under an assumed name. A source claims that his real name is Juan Carlos Oviedo, and he's 29, a year older than listed in the team media guide.
