David Hernandez, who pitched for Arizona last season, signed a one-year deal with the Phillies as a potential closer

With rumors swirling about the Phillies potentially dealing closer Ken Giles, they moved to reinforce the back end of their bullpen Wednesday with the signing of reliever David Hernandez. The 30-year old pitched in 40 games with the D'backs last season after returning from Tommy John surgery.

After missing the 2014 season because of Tommy John surgery, David Hernandez returned to the Diamondbacks bullpen last season, posting respectable numbers, with a 4.28 ERA in 33 2/3 innings of work. He walked just 2.9 batters per nine innings, while striking out 8.8 batters. 

In 2011, Hernandez served briefly as the Diamondbacks closer, saving 11 games out of the 74 that he appeared in for Arizona. Over his six seasons in the majors, the right-hander has notched a total of 19 saves with Baltimore and Arizona. Hernandez has pitched in 282 major league games out of the bullpen and made 27 starts while pitching for the Orioles in 2009 and 2010. His career ERA stands at 4.15, with a record of 25-35.

The Phillies and Hernandez agreed on a one-year deal that will pay him $3.9-million in 2016, with opportunities to earn more based on the number of games that he finishes for Philadelphia. If Ken Giles were to be dealt, Hernandez could be in a good spot to win the closer's role out of spring training, upping his chances to pad his income in 2016.
