David Hernandez likely needs Tommy John surgery

The latest pitcher headed for Tommy John elbow surgery is Diamondbacks reliever David Hernandez, who was diagnosed with a torn ulnar collateral ligament.

Ken Rosenthal of FOXSports.com reports that Hernandez will seek a second opinion, but surgery is likely and would cost him the entire season and perhaps some of 2015 as well.

Hernandez posted a career-worst 4.48 ERA last season thanks to serving up 10 homers in 62 innings, but his 66/24 K/BB ratio was very good, he had a combined 2.94 ERA in 2011 and 2012, and he posted a 2.16 ERA in eight appearances this spring.

Arizona has devoted a lot of money and resources to the bullpen under general manager Kevin Towers, so the Diamondbacks are relatively well-equipped to handle the loss of Hernandez, but he was slated to be a primary setup man for closer Addison Reed.
