I'll go ahead and ask the question - why not Yorke? He's now had 50 games at AA and is certainly producing offensively (.901OPS / 144 wRC+, whichever one prefers) and I believe he is regarded as acceptable defensively (SoxProspects calls him "fringe average"), but maybe somebody that sees him more in Portland can chime in there.
You tell him there is no pressure (because the team is predictably in last place in the division already as it is), and he's heading back down once Story and Mondessi are ready with the expectation to work on whatever flaws MLB pitchers expose in his game because they aren't getting exposed at his current assignment.
Plenty of what I think we consider "smart" organizations are bringing guys up after less than 100 games at the high minor levels and letting them learn in the majors and then sending them back if necessary with things to actively work on.
Just a few examples of guys that have come up and stuck, or come up, gone down, come back up, off the top of my head - Cleveland did it with Kwan with only 51g in AA, 26 in AAA and up; Walls only had 55g at AA in 2019 (then the pandemic) followed by 52 in AAA and then up; Atlanta did it with Harris (43g in AA) and Grissom (22g in 2022 and then 40g in AAA this year). I'm discounting the top 10 in the game type prospects like Julio Rodriguez (46g in AA); Franco (skipped AA but 47g in AA) because I don't personally see Yorke as that kind of prospect, and don't believe the industry does either, but I do equate him to someone like Kwan, Walls or Grissom.
He could very well be worse than Kike, Arroyo, Chang, Reyes or Valdez but seeing as to how the "best" among them (Arroyo at an 86 OPS+) to worst among them (Chang at a 35 OPS+) have all ranged between terrible to unfathomably terrible, he could also be better.
At least he'd be more interesting.
