I think Wisdom is a quality reserve in a vacuum but I'm not sure he's got a proper niche to carve out on this roster. So if you're thinking about whether to keep Wisdom you've got to ask yourself three questions:
1. How do you really think Morel can handle 3B? Morel is also a plus-power minus-contact low ball hitter you can't totally trust (currently) at 3b. If Morel becomes a real option at 3B, I think he and Wisdom can both coexist on the roster. If he can't they are just too similar and with Morel's age/contract advantages obviously you keep him
2. Do you have a good compliment for Wisdom, and feel comfortable also rostering him? Wisdom has platoon splits, but I don't think of him as a platoon hitter per se. He hits the bejeezus out of low pitches, particularly soft ones, and I think it just so happens more lefties lean on changeups and curveballs. Do you pseudo platoon him with Madrigal or Tauchman or someone else?
3. Do you like any of the NRI's better? Garret Cooper just straight mashes lefties, no pitch type considerations needed. You give up some raw power and nominal ability to play 3rd, but maybe that's worth it. In a situation where Morel's not cutting it at 3B, maybe you'd like a Smith or a Peralta to pair with him in the DH mix? There's probably only room for one bat-only type on the roster and Wisdom’s a solid choice but not a slam dunk one
