  Scouting Report & Links      
         
  Physical Description: Smaller, athletic frame. Skinny and needs to add strength. Likely will always be on the thin side as his frame does not look like it can support much added size.

Hit: Starts square and in a crouch with his hands low. Simple swing mechanics and short, compact swing. Contact-oriented approach with strong bat-to-ball skills. Tends to slap at the ball and makes a lot of contact on the ground. Rarely swings and misses. Advanced approach and pitch recognition. Sees a lot of pitches and will take what the pitcher gives him. High walk rate in the low minors, but it will be interesting to see if that holds as he moves up and pitchers challenge him more. Needs to hit the ball harder, as right now he primarily finds gaps with weaker contact. Potential above-average hit tool with added strength.

Power: Not a major part of his game. Swing is not designed for power, but rather for contact on the ground or line drives into the gaps. In batting practice, will occasionally elevate to the pull side. Well-below-average raw power at best and game power is below that.

Run: Fringe-average speed. Solid baserunning instincts, but not a major stolen base threat.

Field: Smooth, fluid actions. Solid range and instincts and has a reliable glove. Comfortable charging or ranging in either direction. Has the actions and range for either middle infield position, but lack of arm strength will likely push him to second base. Began to see time in the outfield midway through the 2025 season. Potential average defender at second base.
  Arm: Below-average arm strength. Accurate arm. Lacks arm strength for shortstop and even on the light side for second base, but passable there.

Career Notes: Tore his ACL 12 games into the 2023 season and missed the rest of the year. Was named to the Horizon League All-Freshman Team and the Horizon League All-Tournament Team in 2022. Had a setback during his rehab after signing and as a result, did not make his pro debut until beginning a rehab assignment in July 2024, almost a year after he signed.

Summation: Potential emergency up-and-down middle infielder. Ceiling of a contact-oriented utility infielder. Strong approach and contact skills, but lack of impact limits upside. Needs to get stronger and get his exit velocities to even fringe-average to reach his potential. Lack of impact will be more noticeable as he moves up the ladder. High baseball IQ. Lack of arm strength could limit him to second base, but value would increase if he can stick at shortstop.
