Body: 5-7, 160-pounds.
Hit: RHH. Narrow, balanced setup. Taller posture, with knee bend present. Hands rest above the shoulder at ear level, with barrel lying flat. Begins load with toe tap backwards as weight is shifted into back side. Hands work to slot as barrel gets more vertical. Weight shifts back to front side during aggressive stride forward. Creates some separation, with hips firing quickly upon the stride. Hands work quickly thereafter, with solid bat speed and getting solid extension. Hands work directly through the zone and stay close to the body. Barrel path shows slight uphill trajectory. Gap-to-gap approach present, with feel for the pull side and up the middle. mph bat speed with g of rotational acceleration.
Power: 97 mph max exit velocity (86.5 avg.); 337-foot max batted distance.
Arm: RH. INF - 76 mph. Show full arm path out of the glove and creates good depth behind. Releases from higher slot, with some aggressiveness in arm action. Gets some carry on his throws and showing solid accuracy.
Defense: Exhibits solid footwork, soft hands, and good body control. Moves well laterally, with ability to show range. Gets decent reads and first step, but could show more urgency when working downhill.
Athletic Testing: 7.38 runner in the 60-yard dash; 23.20-inch max vertical jump.
Vizual Edge: 83.44 Edge Score.
