  Scouting Report & Links      
         
  Physical Description: Tall, sturdy frame with some room to add strength in his upper body.

Mechanics: Throws from a high-three-quarters arm slot starting on the third base side of the rubber. Jerky delivery with a lot of moving parts that he struggles to consistently repeat. Pronounced arm swing behind. Medium leg kick. Very high release. Stiff arm action coming forward. Short strider for his height.

Fastball: 94-96 mph. Topped out at 97 mph in spring training look in 2026, but topped out at 101.8 mph in college. High-spin pitch that is a potential outlier fastball both in terms of velocity and shape. Pitch plays up in the zone and averaged just under 23 inches of IVB. Type of fastball shape that is very difficult to find and has potential for premium bat-missing ability. Command and control are major works in progress; struggles to throw strikes.

Slider: 88-91 mph. Short, tight rotation at its best. Pitch showed bat-missing ability in college, but he struggled to consistently land it in the zone.

Splitter: 84-86 mph. Work in progress. Late dive at its best. Rarely used in college, but flashed bat-missing ability. Showed intriguing shape during spring training 2026, looking like a screwball at times with a very low spin rate.
  Career Notes: Attended Nicholls State for two years, working as a starter, before transferring to LSU for the 2025 season. Had his best performance as a freshman, when he was named National Freshman Pitcher of the Year by both Collegiate Baseball and the NCBWA. Pitched out of the bullpen at LSU as they won the National Championship. Participated in the MLB Draft League after the 2025 college season ended.

Summation: High-variance arm with great size and extremely intriguing fastball characteristics, but a very inconsistent track record of throwing strikes. Fastball has the potential to be a premium offering, but needs considerable work with his strike-throwing. Both secondaries flash potential but are very inconsistent. High-ceiling, low-floor profile, but at his best will show late-inning stuff.

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