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 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.

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.
