Physical Description: Tall, sturdy pitchers frame. Heavier than listed. Thick lower half. Minimal remaining projection in lower half, but some in upper body.

Mechanics: Throws from a three-quarters arm slot from the first base side. Very quick arm. High-effort, hard-to-repeat delivery with a lot of moving parts. Doesn’t effectively incorporate his lower half. Starts in the stretch with his hands set at his waist. Utilizes a medium leg kick and has a long arm swing behind before landing on a stiff front leg and falling off to the first base side. Will cut delivery off at times and doesn’t stay in line to the plate. Inconsistent release.

Fastball: 93-96 mph. Has reportedly topped out at 100 mph. Pitch has some life, but is on the straight side. Velocity has steadily increased since he signed. Sat 91-93 mph during 2016 Fall Instructional League and then was 93-95 mph during 2017 Spring Training. Has the velocity to overpower hitters in the low minors, but fringy command profile will be tested at higher levels. Has shown surprisingly good control given his high-effort delivery. Potential plus-plus offering with refined command and control.

Slider: 83-85 mph. Short, vertical break. Inconsistent release and shape. Doesn’t stay over the ball consistently. Will wrap ball and yank glove side. At its best, pitch with flash above-average potential with depth.

Splitter: 86-89 mph. Hard late tumble down in the zone when at its best. Will flash solid-average potential. Pitch is inconsistent, but has already shown significantly more potential than his changeup.

Changeup: 90-93 mph. Looks like a fastball he takes something off of. Work in progress, lacks separation from fastball. Below-average potential. Seems to have scrapped the pitch in favor of a splitter as of Spring Training 2018.

Career Notes: Participated in Fall Instructional League in 2016 and 2018.

Summation: Signed late and still on the raw side, but shows the early makings of a very intriguing bullpen arm. Fastball has plus-plus velocity and if his slider or splitter take a step forward, has the potential to feature in a late inning role at the major league level. Significant gap between what he is now and his ceiling, with a lot of development remaining. One of the most interesting bullpen arms in the Red Sox low minors.
