Diamondbacks recalled RHP David Hernandez from Triple-A Reno. Hernandez has spent the past few weeks trying to right the ship at the minor league level, posting a 0.93 ERA, 1.14 WHIP and 12/5 K/BB ratio over 9 2/3 innings. With the struggles at the backend of the Diamondbacks bullpen this season, he could quickly work his way back into a late-innings role.
