  Scouting Report & Links      
  Physical Description: Tall, athletic frame. Loose and projectable with room to add strength as he physically matures. Likely to add good weight upon being introduced to a professional strength and conditioning program.

Hit: Starts open and vertical with his hands high. Quiet load with a very short leg lift. Fluid swing with strong feel for hit. Quick hands. Plus bat speed. Ball jumps off his bat and has already shown the ability to turn on velocity. Knows the strike zone and has strong bat-to-ball skills. Advanced approach for a high school hitter. Will use all fields and does not try to do too much at the plate. Potential plus hit tool.

Power: Strong for his frame with good extension in his swing. Has already shown the ability to drive the ball in the air to all fields. Needs to add some strength, and if he does, will turn doubles in the gap into home runs. Fringe-average power right now, but has the potential for above-average to plus power at his peak.

Run: Fringe-average speed. Good instincts, but not a burner. Will play faster than his foot speed because of how he reads the game.

Field: Instinctual defender with very fluid actions. Looks like he is gliding on the field. Soft hands and solid footwork. Moves well and has plenty of range for shortstop. Confident defender; will take a flashy infield. Potential above-average to plus defender at short.
  Arm: Plus arm, plenty for shortstop. Able to make all the throws with plenty of zip.

Notes: Was seen as the consensus top prospect in the 2021 MLB Draft. Attended the same high school as ex-Red Sox Adrian Gonzalez and Twins 2019 first-round pick Keoni Cavaco, with whom he shared an infield, putting him on scouts' radars early. Switch-hit when he was young but decided to focus on hitting left-handed after the eighth grade. Was committed to USC when drafted.

Summation: Has all the tools you look for in future everyday shortstop. Game comes easy to him. Potential for four above-average-or-better tools. Should be able to stick at shortstop and hit for a high average with power. Hit-over-power at the plate at this point, but both tools project as at least above-average. One of the best, if not the best, defenders in the 2021 draft. Complete profile on both sides of the ball gives him an all-star ceiling.

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