AP Sources: Marlins' Nunez faces ID issue - Baseball- NBC Sports Florida Marlins closer Leo Nunez has been playing under an assumed name, and the issue prompted him to return Thursday to his native Dominican Republic, two people familiar with his immigration status said. Both people said the Marlins have been aware of the issue for several months. One of the people said Nunez's real name is Juan Carlos Oviedo and he's 29, a year older than listed in the team media guide.
More money goes to 16 and 17 year olds then the older prospects in the DR. Same reason why Tejada lied about his age too.
