  Scouting Report & Links      
         
  Physical Description: Average frame and build without much remaining projection.

Mechanics: Works out of the stretch from the middle of the rubber. Three-quarters arm slot. Long arm swing behind and big recoil with his arm after release.

Fastball: 92-95 mph. Will show some run to the arm side. Good velocity but very hittable. Well-below-average command and control.

Cutter: 85-88 mph. More promising than the fastball but does not throw as often.

Slider: 81-87 mph. Inconsistent pitch that will vary in shape. At higher velocities, blends into the cutter. At lower velocities, will show bigger, 10-to-4 break when he finishes the pitch.
  Changeup: Mid-80s. Clear third pitch he does not throw often.

Career Notes: Moved into a full-time relief role in 2024 after starting in the DSL and working long outings, often in a piggyback role, in 2023 in the FCL. Really struggled in his initial exposure to Low-A in 2024 and was demoted back to the complex after walking 18 hitters in 8 innings over seven April appearances.

Summation: Potential low-minors depth arm. Has shown interesting velocity, but has been very hittable and showed poor control.
