From what I read here, he will be a draft eligible Sophomore and he is still a growing lad. He should be a bulldog, tune his craft, and then rise in the draft...

"Fristoe's stuff and performance varied on the showcase circuit last summer, as he mixed good and rough outings at the PDP League, struggled to throw strikes at East Coast Pro and rebounded with his best effort at the Area Code Games. Scouts were looking forward to seeing what progress he might make this spring, but the Kentucky high school season got cancelled before he even took the mound. That may make it difficult to take him early enough to divert him from Mississippi State, where he'd be Draft-eligible as a 21-year-old sophomore in 2022.

Fristoe's fastball ranged from 88-90 mph to 91-94 at different times last summer, featuring some armside run. He has a very projectable 6-foot-4 build and could sit in the mid-90s once he matures physically. He lacks consistency with his secondary offerings but shows the promise of a four-pitch arsenal with flashes of a low-80s slider, a curveball with more depth than power and the makings of a changeup.

Because he's still growing into his tall frame, Fristoe doesn't always keep his long limbs in sync in his delivery on a consistent basis. His control and command are still works in progress but should get better as he improves his strength and mechanics. He could blossom into a top-two-rounds prospect after a couple of seasons in the Southeastern Conference."
