I wouldn't know Humphreys if he walked into my living room, but by going thru his numbers and every scouting report I can find, he is a poster boy for a Tribe SP prospect. He's probably at least two years away, and will run up against the options clock. I wouldn't be surprised to see the Tribe petition to extend the clock, due to TJS.
Good size kid, average fastball with two average to better than average off speed offerings....impeccable command and control to both sides of the plate. Sounds like just about everybody in the present and immediate future rotation.
Just a thought about any comparison to Plutko. Plutko plus a few ticks on his fastball turns into Civale and Bieber...not as an end result, but as a mold.
The kid pre TJS didn't walk many, didn't give up many hits, didn't give up dingers, and had a ridiculous K/BB ratio. Post TJS he was sitting 93 MPH.
He was a lowly 18th rounder out of HS, but a few years of collegiate results similar to what he did in lower level pro ball would have zoomed him up the draft board.
We may never hear his name again, or he may be assigned to the pen at some point, but right now he certainly profiles as a Tribe starter.
