Scouting grades: Fastball: 65 | Curveball: 60 | Slider: 60 | Cutter: 60 | Changeup: 45 | Control: 50 | Overall: 55

Scouts have followed the Witherspoon twins since high school, with the Diamondbacks trying to sign Malachi to an over-slot bonus as a 12th-rounder in 2022. Though they have similar stuff, Kyson since has surpassed him as a prospect after performing significantly better in their time at Northwest Florida State JC and Oklahoma. He has much more of a starter look and should be the first college right-hander drafted in 2025.

Witherspoon has swing-and-miss stuff, starting with a mid-90s fastball that peaks at 99 mph and stands out more for its power than its modest life. His mid-80s slider can touch 91 mph while featuring both horizontal action and depth, and he'll turn it into an upper-80s cutter that he uses just as often. He's showing more consistency with his low-80s downer curveball, giving him another plus offering, while his upper-80s changeup is a work in progress that gets too firm but will show interesting fade at times.

Witherspoon uses a compact arm action to generate quality stuff with little effort. His athleticism and mechanics have translated into improved control and command this spring, and better location has made it easier for him to get hitters to chase outside of the strike zone. He has all of the ingredients to become a frontline starter.

The Witherspoon twins began attracting attention as Florida high schoolers, with the Diamondbacks making a run at signing Malachi for an over-slot bonus as a 12th-rounder in 2022. Kyson surpassed his brother as a prospect after outperforming him in three college seasons together at Northwest Florida State JC and Oklahoma. After he topped the Southeastern Conference with a 5.4 K/BB ratio last spring, he unexpectedly lasted 15 picks in the Draft before the Red Sox gladly signed him for $5 million.

Witherspoon can get chases and miss bats with all five of his pitches, the best of which is a mid-90s fastball that reaches 99 mph and compensates for relatively modest life with plenty of deception. His top secondary offering is an upper-80s cutter that reaches 92 mph, with his tight mid-80s slider and big-breaking upper-70s curveball close behind. He doesn't have the same trust and consistency with his upper-80s changeup, which is too firm but flashes interesting fade.

If Witherspoon can do a better job of commanding his slider and landing his curveball in the zone, he could have four plus offerings. He has a compact arm action that produces quality stuff with little effort and makes it difficult for hitters to pick up his pitches. His athleticism translated into more consistent mechanics and location during his junior year with the Sooners, giving him the look of a frontline starter who should move quickly in pro ball.
