I would also like to add that Outman has taken his defensive chops to Detroit as well. The last Tigers game I watched, he took a bad route and let a ball get over his head.
This would be my arguments for Roden promoted over Jenkins at this current moment:
Roden is on the 40-man. Jenkins is not. This plays out in multiple ways, the least of which is that the Twins would have to make a roster move to DFA someone. There is enough chaff on the 40-man that they could DFA someone today and make room for him if you needed him. It matters more in roster construction after the season. I took this off of Copilot (results may vary), but it doesn't sound like that the Twins need to add him to the 40-man in November to protect him from the Rule-5 draft. If there is a labor stoppage, he could still report to spring training and the minors since he is not on the 40-man roster and could be promoted as soon as baseball resumes. The MLBPA is making a hard push to change the number of years before arbitration or free agency, and I wouldn't want the best prospect to lose a year of that due to some crazy grandfather rules or adjustment to the arbitration rules. I'd rather the Twins go into this with their eyes wide open, as they have been shut for most of the past 3-5 years.
Rule 5 Draft context (taken from Copilot)
Players signed at age 18 or younger must be on the 40-man roster within five seasons; those signed at 19+ must be protected within four years.
Jenkins is 21, so he’s not in immediate Rule 5 risk, but if Minnesota doesn’t add him to the 40-man list before the 2027 deadline, he could become eligible for the Rule 5 Draft
While Roden is touted as a great OF, he is not considered the backbone of the future like Jenkins is. Both have injury history. If I'm going to sacrifice somebody to the rigors of MLB vs AAA, I'd rather it would be Roden. I want Jenkins to prove that he can stay healthier longer than a Klondike bar can stay frozen in a corn field during a hot Southern Minnesota day before I trust to start his clock. Jenkins probably would have been up here already had he not been injured.
As for current roster construction, you can bring Roden up right now. Since roster construction typically works itself out, we now do not have enough LHB to fill out a platoon whereas at the beginning of the season, we had too many options. Roden could come in for Fedko and Jeffers would take Gray's spot. If Kreidler did get hurt, Arcia or Gray would be a train ride away and you could fill in-game issues with Lee, Lewis, Caratini, and Bell. This arrangement is likely only for a few weeks if you expect Jeffers to be traded by the deadline.
We need Roden for more immediate help. That doesn't mean that Jenkins isn't ready as he likely is. There is more to a roster than just saying that the player is ready. Until the economics change in baseball, the Twins have to do shrewd moves like this to keep their players in-house and cheap for as long as they can. Ultimately, that is why Jenkins will need to stay in the minors at least until 2027.
