Diamondbacks placed RHP David Hernandez on the 15-day disabled list, retroactive to March 27, with a torn right elbow ligament.

Hernandez will visit Dr. James Andrews for a second opinion on his right elbow Monday, at which point it's likely Tommy John surgery will be recommended. He'll obviously miss the 2014 season.

David Hernandez will visit Dr. James Andrews for a second opinion on his right elbow Monday.

An MRI Friday showed the right-hander has a torn ulnar collateral ligament in the elbow, so he's likely headed to season-ending surgery. If Andrews' diagnosis confirms the injury, Hernandez will likely undergo the surgery Tuesday.

An MRI has revealed that David Hernandez has a torn ulnar collateral ligament.

It's more awful news for the D'Backs, as they're going to lose one of the key cogs in their bullpen for the season. Hernandez will get a second opinion, but Tommy John surgery is almost surely on the horizon. The hard-throwing has posted a 3.42 ERA with 241 strikeouts over 200 innings across the last three seasons for Arizona.

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.

Diamondbacks optioned RHP David Hernandez to Triple-A Reno.

It's been a nightmare season for Hernandez, who owns a 5.59 ERA after allowing two more runs Saturday night. He's more talented than what he's shown this year, so maybe some time in Triple-A will get him straightened out. A corresponding roster move will be made on Sunday.

David Hernandez struck out two in a perfect ninth Friday to earn a save against the Brewers.

The Diamondbacks used both J.J. Putz and Heath Bell in the eighth tonight and then picked Hernandez over Brad Ziegler for the ninth. It all worked out fine, even though Hernandez has given up seven runs over his last 5 1/3 innings of work. On the season, Hernandez has given up eight homers in 41 1/3 innings, which isn't what one wants to see from a closer. It's as many as he allowed in 137 2/3 innings total in 2011-12. Obviously, Hernandez is in the mix for saves now, but he can't be counted on to help in the category.

With Heath Bell having pitched three straight days, David Hernandez got the call in the ninth on Friday and protected a one-run lead against the Phillies.

It was Hernandez's first save of the year. After a rough April, he's turned in four scoreless innings over the last week. The Diamondbacks would prefer Bell hold on to the closer's gig, but Hernandez is ready and waiting should Bell falter.

Called upon with J.J. Putz unavailable, David Hernandez blew a save against the Giants Wednesday, allowing a game-tying homer to Brandon Crawford in the ninth inning.

Hernandez had to pitch out of a jam even after allowing the one-out dinger, as he gave up a two-out single and a walk before getting Marco Scutaro to end the threat. Both Hernandez and Putz have struggled of late, but it will surely be Putz that gets the next save chance.
