  Scouting Report & Links      
         
  Physical Description: Medium, athletic frame. Filled-out, strong, physical build. Minimal remaining projection.

Mechanics: Throws from a low three-quarters arm slot, starting on the first base side of the rubber. Max-effort delivery. Starts with his back to the hitter and front side facing the third base dugout. High leg kick that he tucks behind his lead arm. Long arm action and then comes across his body. Head whack. Falls off hard to the first base side. Shortens leg kick from the stretch.

Fastball: 94-96 mph. Has topped out at 99 mph in the past, but has not shown that velocity in 2025. Throws both a four-seam and a sinker. Uses the four-seam mostly with left-handed hitters, but will throw it up in the zone to hitters from both sides. Primarily uses the sinker to throw inside to right-handed hitters. Command and control are works in progress. Has the tendency to yank the pitch and miss glove-side. Potential average offering.

Cutter: 90-93 mph. Short, horizontal break. Throws frequently, especially early in counts. Designed to get ahead and generate weak contact. Potential fringe-average offering.

Slider: 84-86 mph. True slider with two-plane break. Inconsistent shape, but flashes bat-missing ability. Fringe-average potential.
  Sweeper: 79-81 mph. Long, horizontal break. Able to land in the zone or bury down and away, out of the zone. Changed grip on the pitch late in the 2024 season. Potential average offering.

Changeup:
85-87 mph. Firm, two-seamish shape. Shows sink on occasion. Inconsistent, struggles to land in the zone, with most not competitive. Potential below-average offering.

Career Notes: Played in the MLB Draft League in 2023 after his final year at Rider. Was not drafted and spent the next year revamping his arsenal at Tread Athletics while acting as a volunteer coach at Rider. Increased his max velocity from 95 mph in college to 97-98 mph after graduating. Signed with the independent Indy Ballers in 2024, but continued to work out at Tread and signed with Boston in April 2024 before playing in any independent games.

Summation: Potential organizational depth arm. Ceiling of an emergency up-and-down, multi-inning reliever. Fastball, cutter, and sweeper all will flash bat-missing ability, but needs to refine command and control and find more consistency with his higher-octane arsenal. Lacks a go-to out pitch, though his sweeper looks like it could get there. Velocity gains shown during the 2024-25 offseason have not held. Pitches backwards often.
