"I love how the organization has treated me since I've been over here," Hernandez said. "I can see myself living here one day past baseball. I'm definitely grateful and hopefully I can be here well after two years."
Hernandez joined the Diamondbacks via trade in 2011 from Baltimore for third baseman Mark Reynolds. Hernandez has a 3.15 ERA in 141 career relief appearances and has continued to improve over time, including setting career-highs last season with 11 saves, 74 games and 77 strikeouts. So far this season, he carries a 2.90 ERA with 45 strikeouts.
"He's been great for us since he's come over here," Diamondbacks manager Kirk Gibson said. "He's been dominant for us, he's healthy and he's got a golden arm. We believe in him and what he can do in the future."
