  Scouting Report & Links      
         
  Physical Description: Large frame. Soft body. Thick lower half with minimal remaining projection.

Mechanics: Throws from a three-quarters arm slot from the first base side. Begins facing the third base dugout, then steps toward first to start delivery. No wind-up, medium-high leg kick. Short arm action behind. Short strider.

Fastball: 94-97 mph. Tops out at 98 mph. Primarily throws a sinker that shows hard, boring action and induces a high groundball rate. Will mix in a four-seam fastball at times as well up in the zone. Command is below-average and needs to improve. Had a substantial velocity increase midway through the 2024 season jumping from the low-90s to the mid-90s. Potential above-average pitch.

Slider: 83-86 mph. Slurvy with long, horizontal shape. Lacks feel and consistency. Potential below-average offering.

Curveball: 79-82 mph. Vertical shape. Potential below-average offering.
  Changeup: 82-85 mph. Firm pitch that looks like a fastball he took something off of. Lacks movement and feel. Work in progress that he uses infrequently. Potential well below-average offering.

Career Notes: Participated in 2020 Fall Instructional League. Participated in the Fall Performance Program in 2021. Worked as a starter/piggyback reliever until moving into more of a traditional bullpen role in 2023, although the organization leaned on his ability to throw spot starter/bulk innings in 2024 as well, at least until his midseason velocity spike made him a more interesting short-relief prospect.

Summation: Potential mid-minors depth reliever, but is trending upward with recently added velocity. Ceiling of an organizational reliever. Fastball can generate groundballs, but has missed more bats as the 2024 season has gone on. Secondary pitches are still works in progress. Has a ways to go developmentally and has to drastically improve his command and secondary offerings in order to push towards the high minors.
