  Scouting Report & Links      
         
  Physical Description: Small frame, but physically mature for his age. Athletic build and strong lower half. Has some remaining projection in his upper body, even after adding 40 pounds since signing.

Hit: Starts open and vertical with his hands high. Utilizes a leg kick timing device. Strong contact skills and feel at the plate for his age. Average bat speed, shows above-average barrel control. Swing is short and direct to the ball. Good feel for the strike zone and will rarely chase. Potential average hit tool at least.

Power: Average raw power. Sneaky power for his size, but swing is mainly geared towards doubles on line drives in the gap right now. Projects for below-average in-game power.

Run: Below-average speed. Not a major part of his game. Plays faster than his speed grade due to athleticism and instincts.

Field: Potential fringe-average defensive profile. Fluid in the field. Hands work. Average range at present and given lack of athleticism, could become an area of concern based on how he physically matures. Primarily played shortstop early in his pro career, but has also seen time elsewhere in the infield and primarily played second base in 2022, mostly in deference to Marcelo Mayer.
  Arm: Plus arm. Plenty for the left side of the infield. Confident in his arm.

Career Notes:
Signed to a mid-range bonus on his 16th birthday in 2018. Has reportedly already drawn trade inquiries early in his career. Participated in the Fall Instructional League in 2019 and 2020, and stood out as a standout prospect for scouts at 2020 Instructs. Participated in the 2021 Fall Performance Program. Participated in 2022 Winter Warm-Up. In 2023, reported to camp late due to visa issues and started the season in extended spring training, technically on the injured list. Missed two weeks in June 2023 with a strained left hamstring. Missed the final three weeks of the 2023 season after being placed on the restricted list for unreported reasons, then later was removed from the Arizona Fall League after two games, reportedly for a violation of the Minor League Domestic Violence, Sexual Assault, and Child Abuse Policy. During his suspension, played abroad, including representing Venezuela in the WBSC U-23 World Cup, where he was named to the All-World team.

Summation: Potential up-and-down utility player. Ceiling of a solid utility player with contact skills and positional versatility. Not physically imposing, but has a blend of instincts and ability that stands out. Has feel for hit and at least an average defensive profile to go along with a plus arm. Will stick on the left side of the infield for now.
