  Scouting Report & Links      
         
  Physical Description: Tall, sturdy pitcher's frame. Heavier than listed. Thick lower half. No remaining projection.

Mechanics:
Throws from a high three-quarters arm slot from the first base side. Quick arm. High-effort, hard-to-repeat delivery with a lot of moving parts. Does not 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 struggles to stay in line to the plate. Inconsistent release.

Fastball:
93-95 mph. In the past, has sat 94-97 and reportedly topped out at 100 mph. Lacks life, 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 well-below average command profile will be tested at higher levels. Pitch can miss bats, but command and control have a long way to go. Plus-to-better velocity, but pitch plays closer to above-average due to lack of command and life.

Slider:
83-86 mph. Short, hard 11-to-5 break. Inconsistent release and shape. Struggles to consistently stay over the ball and land it for strikes. Will wrap the ball and yank glove side. At its best, pitch with flash above-average potential with depth.
  Splitter: 87-89 mph. Hard, late tumble down in the zone when at its best. Pitch is inconsistent, but has already shown more potential than his changeup. Below-average potential, but lacks consistency and has rarely thrown in outings scouted in 2022.

Changeup:
Scrapped in favor of the splitter in 2018. Was 90-93 mph. Looked like a fastball he took something off of. Work in progress, lacked separation from fastball. Had below-average potential.

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

Summation:
Projects as a mid-minors depth relief arm. Ceiling of a Triple-A organizational reliever. Fastball has shown impressive velocity in the past, but lacks command and needs either his slider or splitter to take a step forward.
