Let's take context here. Both Granite and Wade have spent time on the DL this season, and as noted, that makes it difficult to promote (side note, I do think Wade should get the call to AAA in the not so distant future).
They are very different injury cases. Granite was bothered by an injury during spring training, spent over 3 weeks on the DL, and still isn't hitting well. That has definitely complicated any 2018 promotion plans for him.
But Wade was fully healthy this spring, and healthy and hitting well into mid-May. He didn't get hurt until he collided with a wall on May 19. Given the Twins still hadn't even promoted him to AAA by that point, even while repeating AA with improved power etc., there really isn't a case that the injury has seriously impacted their promotion plans for him this year.
