Parnell, 30, made just one appearance for the Mets last season before he was forced to undergo Tommy John Surgery in April. Because of the rehab, Parnell is not expected to be ready to work out of the bullpen for the start of the 2015 season.
Parnell has spent his entire career with the Mets since debuting in 2008. His best two seasons came in 2012 and 2013. In 2012, Parnell threw 68.2 innings and finished the year with a 2.49 ERA while striking out 61 batters. In 2013, he pitched 50 innings with a 2.16 ERA with 44 strikeouts and 22 saves.
New York's biggest offseason acquisition has been outfielder Michael Cuddyer, who signed a two-year, $21 million deal. The Mets also have been rumored to be interested in trading for Colorado Rockies shortstop Troy Tulowitzki.
The Mets finished second in the NL East with a 79-83 record last season.
