"December 12th is the deadline for teams to decide whether to tender contracts to arbitration-eligible players on their 40-man rosters. With that in mind, here is the first of two articles focusing on some potential non-tender candidates and the possible fallout for 2012.

The Marlins' closer is currently working through some complicated legal issues in his native Dominican Republic after coming clean in September to faking his identity. He posted a 4.06 ERA and a career-high fly ball rate this season and is poised to make about $6 million in his final year of arbitration, so there's a good chance he would have been a non-tender candidate regardless of his identity situation. The Marlins are hopeful he'll be able to secure a visa in time to pitch in the United States next season, but with a wealth of options available in free agency, fantasy owners should expect a new closer in South Florida for 2012.
