  Scouting Report & Links      
         
  Physical Description: Medium, athletic frame. Sturdy lower half, some remaining projection in his upper body.

Mechanics: Throws from a high-three-quarters arm slot starting on the first base side of the rubber. High leg kick which he tucks in behind his lead elbow. Long arm swing behind. Quick forward from a more vertical slot and high release. Slight head whack, falls off to the first base side. Repeats delivery well. Slightly above-average extension at 6.41 feet on his fastball.

Fastball: 95-98 mph. Has topped out at 100.2 mph. Velocity took off during his first spring training and jumped multiple grades after he sat 92-94 mph and topped out at 97.7 mph at LSU as a junior. Low-spin fastball with solid life. Tough to square up from a vertical angle. Strong command and control profile. Throws a ton of strikes, but struggles to miss bats with it. Potential plus offering.

Slider: 86-89 mph. More vertical than horizontal. Can really snap off with depth. Lower spin rate, but missed a ton of bats in college. Does not land in the zone that often, but throws it competitively enough most of the time, leading to a high chase rate. Significantly improved at LSU his junior year. Potential plus offering.

Curveball: 80-83 mph. 12-to-6 shape with a lot of vertical depth. Throws it competitively frequently and effectively uses it in sequence with his improved arsenal. Uses a lot against left-handed hitters. Potential above-average offering.

Changeup: 87-89 mph. Low-spin offering with late dive. Feel is improving and is still learning to consistently land it competitively. Potential fringe-average offering.
  Career Notes: Transferred from UC San Diego to LSU for his junior season following a breakout summer in the Cape Cod League and playing for the Team USA Collegiate National Team. Was the Saturday starter for LSU behind 2025 3rd-overall pick Kade Anderson. Finished third in Division I in strikeouts as a junior behind Anderson and Tennessee's Liam Doyle, the 5th-overall pick. Was a roughly consensus top 50 draft prospect and fell to the Red Sox at the 87th pick overall. Pitched in the 2026 Spring Breakout game, in which he was arguably the breakout player on the Red Sox roster after showing big velocity gains in his one inning of work.

Summation: Potential mid-rotation starter with ceiling for more if his improved stuff from Spring Training 2026 carries over into the season. Has a polished arsenal and solid control profile already, and now has shown flashes of high-end raw stuff. Was seen as more of a high-floor, lower-ceiling type coming out of college. Fastball was on the lighter side, but gained velocity quickly in the Red Sox pitching program. Feel for spin stands out, and both slider and curveball have at least above-average potential. Changeup offers a viable fourth pitch but could use some refinement. Solid arm to add into the Red Sox pitching development program who brings a different look given his release height and approach angle. Strong makeup, hard worker.

Note: This page will be updated with a complete scouting report after the scouting team has seen the player in regular season game action.
