Miami Herald:

SANTO DOMINGO — The Florida Marlins pitcher known as Leo Núñez will be criminally charged in his home country for using a false identity, after making a startling confession earlier this week to Dominican authorities: his real name is Juan Carlos Oviedo, the prosecutor’s office said Friday.
The relief pitcher, who returned home Thursday, was placed on Major League Baseball’s restricted list and removed from the Marlins’ roster.
Jacqueline Lamarche, spokeswoman for the Dominican Attorney General’s Office, said Oviedo faces jail time if convicted but did not know when he would be charged. With a false identity and possible conviction on his record, he could have problems obtaining a United States visa to return.
His team bio says the pitcher, who turned pro in 2000 when he signed with the Pittsburgh Pirates, was born in 1983 and is from Jamao del Norte. But the player now says he was born a year earlier, and he’s from Bonao. Núñez? His best friend.
