Jack Jorgenson, Reedy (TX), 2025 Positional Profile: RHP RHP…aggressive on mound. Like the upside to FB. Can improve execution in zone with FB, especially working up/down. Slider/cutter shows solid action. Did show what I felt was a CB showing down action. Love the way he goes about it on the mound. Body: 6-1, 200-pounds. Solid build with strength present. Frame/build will continue to add strength. Delivery: Side step rocker, good job of using lower 1/2. Cross step delivery. Aggressive. Arm Action: RH. Arm speed present. Full circle, work well. HTQ slot with good finish. FB: T92, 89-91 mph. Fair down plane, ability to pitch up in zone. Arm side tail present. Must firm down/up execution. Will add more velocity. T2304, 2133 average rpm. SL: 80-80 mph. Short breaker, shows solid finish at times. Inconsistent release point. CUT: 84-84 mph. Solid action, good pitch.
