7:52pm: Two sources familiar with Nunez's immigration status say the righty has been playing under an assumed name, reports Steven Wine of the Associated Press.
The Marlins have been aware of this for months, according to Wine's report. One of the sources says Nunez's real name is Juan Carlos Oviedo, and he's actually 29 years old, not 28.
1:14pm: The Marlins placed closer Leo Nunez on the restricted list for undisclosed reasons, according to Clark Spencer of the Miami Herald. Agent Andy Mota declined to comment on his client, who was headed to the Dominican Republic.
Juan C. Rodriguez of the South Florida Sun-Sentinel hears that Nunez isn't being disciplined for inappropriate behavior. He was placed on the list to return to the Dominican Republic and handle a personal matter.
Players on the restricted list do not count toward a team's 25-man or 40-man roster. Teams do not always pay players on the restricted list, so Nunez could be at risk of losing some of his $3.65MM salary depending on the circumstances of the move and whether the MLBPA objects on his behalf.
Nunez will be arbitration eligible for the fourth time this coming offseason and MLBTR's Tim Dierkes projects a $5.8MM salary for the right-hander in 2012, assuming the Marlins tender him a contract. Back in July, Rodriguez reported that the Marlins intended to keep Nunez in 2012.
