David Hernandez fell apart in relief on Tuesday, surrendering five earned runs on five hits while recording only two outs.

No one could have seen this coming. With Arizona up 3-1 in the eighth inning, the normally reliable Hernandez retired two of the first three hitters before giving up four straight hits, including a Troy Tulowitzki three-run bomb. Hernandez took the loss to fall to 3-3 on the season, while his ERA jumped 70 points to 3.47.

David Hernandez (ankle) allowed one run over one inning in his return Tuesday night against the Rockies.

Hernandez left Saturday's game with a right ankle contusion. He gave up one hit (a solo homer to Dexter Fowler) and struck out two.

David Hernandez returned to action on Tuesday August 30.

David Hernandez had X-rays on his right ankle, which came back negative, leaving him day-to-day with a contusion.

Hernandez said he hopes to be back by Wednesday at the latest.

David Hernandez picked up his 11th save of the season Sunday with closer J.J. Putz unavailable.

Putz pitched on Thursday, Friday and Saturday. Hernandez has proven that he can handle the closer's gig, but Putz isn't going anywhere. The incumbent has a 2.91 ERA and 29 saves in 33 chances this season.

David Hernandez tossed a perfect eighth inning on Sunday to set up J.J. Putz's save.

Hernandez was effectively day-to-day over the weekend after getting cut on his finger. The injury apparently had no impact on his performance, as he tallied two strikeouts while throwing seven of eight pitches for strikes.

David Hernandez returned to action on Sunday August 7.

Diamondbacks manager Kirk Gibson isn't sure when David Hernandez will be available to pitch due to a cut on his finger.

Hernandez suffered the cut, according to Gibson, when he "threw something" in frustration following his appearance on Sunday. It doesn't seem like a big deal, so we should consider Hernandez day-to-day.

David Hernandez earned his eight save of the season in Saturday's 3-2 win over the Dodgers.

Hernandez has not allowed a hit in six relief appearances since the beginning of July and is six-for-six in save opportunities over that span. The Diamondbacks are expected to turn back to J.J. Putz (elbow) when he returns from the disabled list later this month, but Hernandez has earned himself more late-innings looks.

David Hernandez earned his sixth save of the season Thursday in Arizona's win over the Cardinals.

Hernandez has provided a steady presence at the back end of the bullpen in the absence of J.J. Putz (elbow) but is likely to lose his job shortly after the All-Star break. Putz has been playing catch all week and could begin a rehab assignment this weekend.

David Hernandez gave up two runs on two hits in one inning of work in Arizona's 7-5 victory Tuesday over Philadelphia.

Entering the game, Hernandez had surrendered only one run in 10 innings this season. But after he got two outs, Ryan Howard singled and Ben Francisco launched his fourth home run. Hernandez has now given up four hits and three runs in his last two relief appearances.

Diamondbacks manager Kirk Gibson said David Hernandez will be the primary setup man for J.J. Putz this season.

Juan Gutierrez, Sam Demel and Aaron Heilman were others that could have been considered for the role, but Hernandez is the best choice. He tossed a scoreless inning Friday, touching 97 MPH on the radar gun a few times. "Just based upon his stuff," Gibson said. "He can overpower people."

Diamondbacks acquired RHP David Hernandez and RHP Kam Mickolio from the Orioles for 3B Mark Reynolds.

Hernandez, 25, posted a sparkling 1.05 WHIP and 79/18 K/BB ratio over 57 1/3 innings this year at the Triple-A level. He's been used as a starter in the past, but the Diamondbacks seem likely to use him as a long reliever at first. Paired with Mickolio, who has also shown some promise in the minors, the D'Backs got a nice package for the strikeout-prone Reynolds.

The Arizona Republic's Nick Piecoro hears that the D-backs "aren't crazy about" the Orioles' Chris Tillman but would be interested in David Hernandez in a deal involving Mark Reynolds.

Piecoro says Arizona views Hernandez as a potential eight-inning man, but it will take more than that to get Reynolds. Josh Bell's name has also been mentioned, and he would be a nice get for the D-backs. The Blue Jays are also interested in Reynolds and have had conversations with Arizona about him as recently as Thursday.

David Hernandez (ankle) is expected to be activated from the disabled list Tuesday.

He wrapped up his minor league rehab assignment with a scoreless inning of relief for Double-A Bowie on Monday night. Hernandez has been sidelined since early August due to a sprained left ankle. He's expected to return in a relief role.

David Hernandez (ankle) struck out all three hitters he faced in a rehab appearance for Double-A Bowie Saturday.

He'll make one more appearance for Bowie on Monday and then will be activated from the DL. Hernandez appeared to have found a home in the bullpen before suffering an ankle injury in early August, and he has some late-inning potential in a relief role.

David Hernandez (ankle) is scheduled to make a minor league rehab appearance with Double-A Bowie on Friday night.

Barring any setbacks, he'll throw there again Monday. It's possible he could return to the major league club sometime next week. Hernandez has been sidelined since early August due to a sprained left ankle.

David Hernandez (ankle) is scheduled to throw live batting practice on September 1.

He had a bullpen session Wednesday that went well. After the live batting practice, he could join Single-A Frederick or Double-A Bowie, if they make the playoffs, for a couple rehab appearances. After that he should be ready to rejoin the O's bullpen.

David Hernandez (ankle) will "definitely" not return from the disabled list when he's eligible on August 20, according to Orioles manager Buck Showalter.

Hernandez has been on the DL since August 5 with a sprained left ankle. A timetable for his return isn't known, but it's clear based on his manager's comments that he has yet to make much progress.

Orioles placed RHP David Hernandez on the 15-day disabled list with a sprained ankle.

The right-hander sprained his left ankle in Wednesday's game against the Angels. Hernandez seems to have found his calling since being moved to the bullpen, as he's posted a 3.29 ERA and 10.9 K/9 rate in relief for the O's. It's not clear how long this injury will keep him out.
