Hernandez, 30, will provide a veteran presence in a Phillies' bullpen that is expected to include Ken Giles, Luis Garcia, Jeanmar Gomez, Elvis Araujo, Dan Otero and Mario Hollands last season. The ex-Diamondback posted a 4.28 ERA in 40 games last season after undergoing Tommy John surgery and missing all of 2014.
Hernandez is the owner of a lifetime 4.15 ERA in parts of six major-league seasons with the Orioles (2009-10) and Diamondbacks (2011-15). He broke into the majors as a starter with Baltimore before switching to relief work, and has been a reliable option out of the 'pen for the Diamondbacks since 2011.
