  Scouting Report & Links      
         
  Physical Description: Tall, athletic frame with some remaining projection. Looks the part, has the room to add strength without impacting his athleticism.

Hit: Starts slightly open with his hands high. Had some pre-pitch hand movement in the past, but cut down on it heading into 2024. Utilizes a toe-tap timing device. Good separation in his swing. Quick hands, solid bat speed. Not the most fluid swing. Has the tendency to get long to the ball and get under it, resulting in a lot of weak popups. Will work counts and has some feel for the strike zone, but is still developing his approach. Will expand the zone against offspeed pitches, but has shown a willingness to take a walk. Is aggressive when he gets ahead in the count hunting fastballs he can hit. Ball makes a different sound when he squares it up. Will go to all fields. Hits the ball hard and was already producing major league-quality exit velocities as a teenager, but tendency to get under the ball has tended to pull down exit velocity metrics in full-season ball. Has struggled more against velocity as he has moved up the ladder. Still has a ways to go in developing his approach and has a wide variance of potential outcomes at the plate, but shows the raw tools to develop a below-average hit tool.

Power: Will show plus raw power in batting practice. As he physically matures, could add even more raw power. Has already shown the ability to impact the baseball in games as well. Hits the ball extremely hard and can drive the ball with backspin. Shows the makings of all-fields power. Batting practice is very impressive when he lets it fly. Hit tool variance clouds long-term power potential, as there are questions if he will make enough contact to tap into that power. Potential for above-average game power at his peak.

Run: Plus speed. Plays faster than he grades out due to his athleticism and agility. Moves effortlessly. Covers ground extremely quickly.

Field: Shows good instincts and reads in center field. Plus range. Takes long strides and glides to the ball. Projects to stick in center field, where he could be a plus defender.

Arm: Above-average arm strength. Plenty of arm for center field.
  Career Notes: Received the largest bonus in the Red Sox January 2021 international free agent class. Missed the first two weeks of the 2021 season for undisclosed reasons. Participated in the 2021 Fall Performance Program. Scouts praised him as the best position player in the FCL during the 2022 season. Would have received a late promotion to Salem in 2022, but was held back at the complex due to a lower back issue and ultimately did not move up. Entered 2023 as a consensus top 100 prospect in the game. Missed time in May and June 2023 due to a left shoulder subluxation before undergoing season-ending surgery in June. Participated in the 2023 Fall Performance Program. Prospect stock slid some entering 2024, ranking on some Top 100 lists. Entered spring training in 2024 in tremendous shape, with the organization very happy with the work he had put in while rehabbing his shoulder and preparing for the season. Started 2024 Spring Breakout game. Missed time in 2024 with several minor injuries/medical issues, including a root canal and a finger sprain suffered while sliding. Started in the 2025 Spring Breakout and Futures at Fenway South games. Began 2025 dealing with a quad injury.

Summation: Potential fourth outfielder who brings speed, defense and some power. Ceiling of an everyday regular capable of adding value in all facets of the game. Highest-variance prospect in the system with a wide range of potential outcomes. Major questions with his hit tool cloud future projection. Really struggled in 2024 after a promotion to Greenville, where he looked overmatched at times at the plate. Injuries have slowed down development considerably, as he missed most of 2023 with a shoulder injury and had several short injury/health-related absences in 2024 that led to roughly 20 games missed. That he was injured again to start 2025 does little to address health-related questions. At his best, will check all the boxes you look for in a prospect his age, and if he reaches his potential, all five tools could grade at least as average, but his highest variance tool is his hit tool, which makes him extremely risky. Swing easily gets out of sync and has not translated to on-field production since 2022.
