Arizona Diamondbacks: 5 unanswered questions before the wild card game

What about the rest of the bullpen?
The middle relievers have been hit and miss this season for the Diamondbacks.
At this point, I would not trust any of them to get big outs in key situations.
I could see Jimmy Sherfy playing a role if the Diamondbacks have a large lead late, and a large lead against the Rockies means a margin of seven-plus runs in the seventh inning.
But Sherfy has also been banged up. He did throw a simulated game to live hitters earlier this week.
Jorge De La Rosa can match up against righties or lefties, but his specialty is stranding inherited runners. Andrew Chafin can get a ground ball or two, but he struggled in the second half.
I would only use David Hernandez against the bottom the order, guys that are not a home run threat.
As far as Fernando Rodney in the ninth, I am not very confident tin his ability to hold a lead late. If the D-backs have a four or five run lead going into the final inning, than fine. But if it is a close game and Bradley is available, I trust him to get six outs more than Rodney to get three.
