ATLANTA -- Patrick Corbin's second stint in the big leagues will be both more and less familiar.
More in the sense that the D-backs left-hander has been here before, but less in that he will be pitching out of the bullpen for the first time in his professional career, other than a couple of appearances as a reliever during Spring Training.
Corbin was scratched from his Triple-A Reno start Tuesday after Daniel Hudson suffered an elbow injury. With Josh Collmenter stepping into Hudson's spot in the rotation, Corbin will be the long man in the bullpen.
Corbin was 2-3 with a 5.27 ERA in five starts for the D-backs earlier this year.
"Not as much nerves," Corbin said of getting the news of his promotion this time around. "I've kind of gone through this, so I'm just going to come here and feel more relaxed and ready to pitch."
Corbin talked to pitching coach Charles Nagy on Wednesday about how to stay loose in the bullpen by playing catch with the outfielders in between innings.
"It's something we'll have to be careful about, and make sure give him appropriate time to get loose in the bullpen," D-backs manager Kirk Gibson said when asked about Corbin's lack of bullpen experience.
The D-backs will try and make sure that when he's brought in Corbin will be starting an inning rather than be asked to get loose quickly and come in during the middle of an inning.
"Not knowing when I'm going to throw is going to be a little different," Corbin said. "We'll see how that goes, I've never done it. I think I'll be all right though."
