According to the Associated Press, Leo Nunez was sent back to the Dominican Republic this week because he was found to have been using a fake name.
Nunez was placed on the restricted list Thursday and is not expected to return to the major leagues this season. According go the AP's sources, the right-hander's real name is Juan Carlos Oviedo and he's actually a year older than his listed age of 28. The Marlins have reportedly known about the issue for several months, but it's not yet clear how they plan to resolve it.
