Positional Profile: OF/2B
Body: 6-0, 165-pounds.
Defense: RH. OF - 87.00 mph. Moves well through baseball, some stiffness to field, has above avg. arm strength from field with longer footwork to throw.
Hit: LHH. Wider stance with body load, balanced in box, above avg. bat speed, drives baseball well consistently to mid/pull side of field.
Power: 92 mph max Trackman exit velocity in bp.
Run: 6.78 runner in the 60.
Positional Profile: OF/SS
Body: 5-11, 150-pounds.
Defense: INF - 78.00 mph. OF - 79.00 mph. IF- higher fielding position, needs development with routes and angles, long release with avg. accuracy to bag. OF- aggressive to field, tends to use two hands to field, avg. momentum on throws to target.
Hit: LHH. Open stance, knee to knee trigger, lays barrel at 90 degrees creating flat path through zone, easier swing with solid contact to pull side of field.
Power: 83.5 mph exit velocity during bp.
Run: 6.92 runner in the 60.
