It's possible, but Pardinho has 24 innings in A ball, Woods-Richardson has 78, and Manoah has 1 in A-. I don't think it's at all unreasonable to project a full season between A and A+ next year, perhaps with SWR hitting AA for half the year in 2020, then AA and AAA in 2021. They may get cups of coffee then, but 2022 seems reasonable just considering where they are and where they need to get to.
Of course, they could utterly dominate and move that timeline up.
