The Diamondbacks are moving forward with their offseason plans under the assumption that right-hander Archie Bradley will remain in the bullpen. What they haven’t yet determined is what role he’ll fill, a variable that gives them some flexibility as they pursue bullpen help.

“We’re going to keep our options open for how the bullpen gets built,” Diamondbacks General Manager Mike Hazen said. “We’re looking to acquire impact bullpen guys. We’re open-minded to role. I think we’re in a little different space than we were last year, where we didn’t have this part of the equation.”

That is to say, they didn’t have a pitcher - Bradley - coming off one of the most dominant seasons of any reliever in baseball. This year, in his first full season in the bullpen, Bradley logged a 1.73 ERA in 73 innings.

Hazen said Bradley will come to spring training and stretch out as a starting pitcher before likely opening the year back in the bullpen. Building him up keeps the option open to start in case of injuries, Hazen said, noting that it’s also the way Bradley is accustomed to getting ready.

Keeping Bradley in a relief role in 2018 makes sense for a number of reasons. The club already has a strong five-man rotation with what looks to be a decent array of depth options, not to mention the eventual midseason return of Shelby Miller from Tommy John surgery.
