John Michael Szefc, Miller School (VA), 2026 Positional Profile: SS/2B Body: 5-9, 158-pounds. Wiry, athletic frame. Hit: LHH. Quiet, balanced setup. Short, slightly uphill barrel path. 66 mph bat speed with 18 G's of rotational acceleration. Power: 93 max exit velocity, averaged 87.3 mph. 322' max distance. Arm: RH. INF-81 mph. Short, quick arm action. Defense: Soft hands, with fluid footwork. ATH: 7.07 runner in the 60. 28.80 max vertical.
6/21/22
5-foot-9, 138-pound lean projectable build. Advanced projectable in the box, Szefc had a max exit velocity of 83 mph. (60.3 mph bat speed average). (20.2 mph hand speed average). Began in a balanced quiet stance with a smooth active load, then used a controlled small leg kick. Had a short simple swing plane, quick efficient bat speed and good extension on his balanced finish. Found multiple barrels with loud contact. Gap to gap tough out approach. Projectable confident while in the infield, made throws at velocities up to 75 mph; had consistent hands, in control fluid footwork, and a clean natural exchange. Fielded the ball out front with athletic movement laterally. Showed a ¾ slot and a short quick arm action with consistent accuracy to the base. During the event, ran the 60-yard dash in 7.38.
