"A couple of years ago I probably would have been more ecstatic, but I've grown to like the bullpen, just the variety of roles you get used in," Collmenter said. "It's definitely closer to an equal in terms of the likability of each role, but if that's where the team wants me, that's absolutely where I'll be."
D-backs manager Kirk Gibson said the team is considering shifting Collmenter to the rotation if starters like Randall Delgado and Trevor Cahill continue to struggle.
Though he has not started a game since 2012, Collmenter had several long stints out of the bullpen last year, including a six-inning one against the Marlins in June. His ability to get stretched out quickly has long been an asset for him.
Collmenter worked four innings and threw 55 pitches in relief Wednesday night against the Giants, which should put him in position to be an option for the rotation next week if the club decides to add him.
"I got stretched out a decent amount in Spring Training," Collmenter said. "A couple of three-inning outings or at least throwing parts of three innings, so it wouldn't take long. That's kind of the nice thing about how my arm works; it doesn't take too long to get there. So maybe one three-inning outing, I'm sure I could go five, no problem."
