It was a relatively quiet Trade Deadline for the D-backs, but that doesn't mean they didn't check a couple of items off their to-do list. 

By trading free-agent-to-be David Peralta to the Rays a few days before the Deadline, D-backs GM Mike Hazen helped clear a spot in the outfield for the team to get a good look at rookie Jake McCarthy.

It seems likely that outfielder Corbin Carroll, the team's No. 1 prospect per MLB Pipeline, will make his debut at some point this year, and if Peralta had still been with the team, there would have been less outfield playing time to go around.

In addition, the D-backs acquired third baseman Emmanuel Rivera from the Royals in exchange for right-hander Luke Weaver.

Rivera gives the D-backs something they did not have a lot of: A right-handed-hitting infielder, and by dealing Weaver they saved themselves from likely non-tendering him this winter.

Could they have done more? Sure, they could have traded some of their veterans for prospects in the lower levels of the Minor Leagues, but rather than add "lottery tickets" as high-upside youngsters are sometime referred to because of their uncertainty, the D-backs valued having mentors in the clubhouse.

"You just have to get to a point where you feel like you're making a good deal [in order] to make a deal, and I just never felt like that was something that we got to," Hazen said. "And so we just held our position where we were. Trading somebody away for a lottery ticket five to six years from now was something we probably could have entertained, versus the value of having those players on our team right now. For me, given that our roster is going to skew younger still as we move through the season, having guys on your team that can help those players along with helping us win games, there was a level of importance [in that]."

Putting the veterans they kept aside, the D-backs could have been big players in the market had they decided to make players like outfielders Alek Thomas and Daulton Varsho or second baseman Ketel Marte available, but they simply were not going to part with players they see as foundational pieces for their next playoff team.

 "We received numerous overtures on all of the above, and we just didn't really engage with it at this point," Hazen said.
