Physical Description: Athletic, projectable frame. Has some room to fill out, but will always be on the thin side. Low-mileage arm.   

Mechanics: Max-effort, arm-heavy delivery. Doesn’t utilize his lower half. Live, quick arm. Throws from a three-quarters arm slot. Brings his arm back and then whips it forward violently. Finishes upright with hard leg recoil and head whack, and does not get much extension. Unique mechanics are off-putting for hitters.

Fastball: 94-97 mph. Tops out in the high-90s when on. Potential plus-plus offering. Pitch shows some life and some natural cut. Loose arm and elite arm strength help him generate easy velocity even though he doesn’t use his lower half to great effect. Well below-average command and control.

Curveball: 75-80 mph. Average potential. Loose and rolls to the plate at lower velocities. Shows sharper break and depth through the zone when he snaps it off at higher velocities, but doesn’t consistently work in that velocity band. Pitch has progressed since he joined the organization, starting out in the low-70s and working in the mid-to-low 80s during the 2016 season. Pitch is at its best in the high-70s. Lacks consistency and feel for the pitch. Will show well-below average some outings and average during others.

Splitter: 84-86 mph. Work in progress, but has flashed at least average potential. Pitch shows late drop at its best and is thrown with deceptive arm speed.

Slider: 81-84 mph. Short 10-to-4 break. Thrown sparingly as a pro.

Changeup: Scrapped the pitch for a splitter during the 2016 season. Was 82-83 mph with below-average potential. Thrown with similar arm speed to fastball. Showed drop and fade in on right-handed hitters. The pitch looked much improved in 2014 Fall Instructional League, but he struggled with the offering during the 2015 season.

Career Notes: Moved to the bullpen full-time in 2016. Redshirted his freshman season at Duke as an outfielder, then transferred to Seminole State to become a pitcher. Brother Jarred is a major league pitcher who has pitched for the Astros, Marlins, and Padres. Participated in 2014, 2015, and 2016 Fall Instructional League.

Summation: Potential to develop into a seventh-inning reliever if he can continue to refine command and control and develop a secondary offering to compliment his fastball. Unique mechanics provide deception, but also put a tremendous amount of stress on his arm and as a result, greatly increases his injury risk. High-risk prospect with low floor, but some upside if things work out.
