  Scouting Report & Links      
         
  Physical Description: Sturdy, athletic catcher's frame. Thick lower half. Looks more than listed weight of 175, and still has room to fill out.

Hit: Average hit tool. Holds bat high, lowers on approach. slight toe tap device. Has some loft in his swing. Aggressive approach, does not work deep into counts. Makes solid contact in the zone but will chase some bad pitches on occasion. Really struggles against changeups and high velocity, does most of his damage against low-90s fastballs. Fares significantly better against left-handers.

Power: Fringe-average power. Impacts the ball, mostly a doubles hitter with occasional over the fence power.

Run: Below-average speed.

Field: Fringe-average defense. Doesn't have the softest hands and can be error prone. Fluid motions.
  Arm: Average arm strength.

Career Notes: Signed out of Venezuela on the first day of the international signing period in 2019 at the age of 16. Missed 2020 due to the pandemic, and then saw limited action in the complex leagues in 2021 and 2022. Was set to participate in the 2022 Fall Performance Program that was canceled due to Hurricane Ian. Entered the 2023 season as Salem's starting backstop and earned a quick promotion to Greenville. Participated in the 2023 Fall Performance Program. Late addition to the 2024 Red Sox Spring Breakout Showcase roster. Started in the 2025 Spring Breakout and Futures at Fenway South games at catcher and DH, respectively.

Summation: Potential solid organizational player. Has not shown the defensive skills to be a serviceable major league backup.
