James Tomlin, IV, St. John Bosco High School (CA), 2029
Positional Profile: OF/RHP Projectable outfielder with a fluid, consistent, and powerful swing at the plate
Body: 5-9, 141-pounds. Athletic build with lean strength and room for continued physical development.
Hit: RHH. Starts from a wide, slightly open stance. Repeatable load into the back hip initated by an easy heel lift. Hands push backwards to create tension throughout the load. Steep, direct bat path that backspins balls with authority to all parts of the field. Rotates powerfully and maintains posture.
Power: 89 max exit velocity, averaged 83.2 mph. 303' max distance.
Arm: RH. OF-84 mph. Compact and tight arm action that fires from the ear. Ball fires out of the hand with moderate carry.
Defense: Utilizes a twichy, athletic lower body to work around the ball and generate power from the ground up. Carries significant momentum from the gather into the throw.
ATH: 7.63 runner in the 60.
