  Scouting Report & Links      
         
  Physical Description: Small but strong frame. Good athlete, minimal remaining projection.

Hit: Starts slightly open with his hands high. Pronounced leg kick timing device. Violent swing that he gets his entire body into. Very quick hands, plus bat speed. Makes a lot of contact in the air. Approach is a work in progress. Will chase frequently and contact skills are a work in progress. Does a lot of damage against fastballs.

Power: Above-average raw power. Makes a lot of contact in the air, specifically to the pull side. Hits the ball hard and optimizes his angles.

Run: Average speed. Not a major stolen base threat.

Field: Will initially be developed at both second base and shortstop. Not a standout defender, but should be solid enough to stay in the infield. Has also played outfield in the past, which could provide an avenue to versatility down the line.

Arm: Average arm strength. Profiles best at second base.
  Career Notes: Followed both his grandfather and father in playing baseball at Arizona. Played for Brewster and Chatham in the Cape Cod League. Graduated as Arizona's career leader in extra-base hits and second all-time in home runs.

Summation: Potential bat-first infielder whose upside will be determined by how his hit tool develops. Checks a lot of boxes with what the Red Sox look for in players with his ability to impact the baseball. Extremely quick hands, hits the ball hard consistently, and can elevate to the pull side. Approach and contact skills are both works in progress, creating a wide amount of variance in his hit tool. If he hits, has MLB regular upside. Not likely to add a ton of value on defense, but also will not hurt a team there and could develop positional versatility.

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