Nunez is a possibility, though he'd probably be a wasted roster spot in 2023 (He's a baby). I don't think any of the pitchers could be kept on the roster all season. I think Kelley might eventually be a solid #2 starter, but he won't be ready for even limited use in 2023. Morris is far worse than Cam Devanney, whom the Brewers exposed in the rule 5 draft, so they're certainly not keeping Morris on the 26 man roster.
