The Tampa Bay Rays officially announced Thursday the signing of Juan Carlos Oviedo, a right-hander who adds depth to the back of the bullpen in 2014 and could emerge as the closer.

Oviedo signed a one-year, $1.5 million contract that can be worth as much as $2.9 million with incentives.

Oviedo, who saved 92 games for the Marlins between 2009 and 2011 when he was known as Leo Nunez, signed a minor league deal with a $2 million club option last January. He spent the season rehabbing from Tommy John surgery on his right elbow and did not pitch for the Rays. The Rays declined his option after the season and paid him a $30,000 buyout.
