Fastball
Hop+
A fastball with hop has a flat approach angle and visually jumps through the zone. When thrown up in the zone, it is more likely to generate a higher swing and miss average. Hop+ of 100 is MLB average.
Fastball
Sink+
A fastball with sink has low backspin and drops through the strike zone. When thrown down in the zone, it is more likely to generate a higher ground ball percentage and lower launch angle. Sink+ of 100 is MLB average.
Fastball
Rise+
A fastball with rise has a high percentage of backspin. When thrown up in the zone, it is more likely to generate a higher fly ball percentage. Rise+ of 100 is MLB average
Curveball
Hammer+
A hammer breaking ball drops vertically with velocity through the zone, or 12-to-6 movement. Hammer+ of 100 is MLB average.
Curveball
Sweep+
A sweeping breaking ball moves horizontally with velocity through the zone. Sweep+ of 100 is MLB average.

OF John Strzechowski (St. Laurence, 2026) currently comes in as the No. 47 ranked prospect in IL. Listed at 6-foot, 160-pounds, Strzechowski has a lean and projectable build. The right-handed hitter has upside in his swing; working with a controlled stride, creating slight hand-separation before footstrike, still remains short and quick to the ball with a loose barrel through the zone, creating extension through contact. Upside athlete and bat to know within the state.
INF John Strzechowski (St. Laurence, 2026) is a two-way prospect to know in the class but he caught our attention as a position player on day one of the event. The right-handed hitter has a long, upside frame and his swing should only continue to tick up as he adds quality strength. He stays short and repeatable to the ball with loose hands and a mature approach utilizing the middle of the field.
RHP John Strzechowski (St. Laurence, 2026) caught some eyes with his above-average pitchability, especially for his age. Listed at a projectable 5-foot-11, 150-pounds with room to add on strength as he matures. The right-hander pounded the zone with all three of his pitches, striking out two against no walks in two innings of work. His fastball cruised at 78-80 mph, topping out at 80.9 mph with slight running action. Showed the ability to keep his curveball down and miss barrels, 67-71 mph with 11/5 shape. Confident in a heavy fading changeup that he could land for strikes in any count, 71-73 mph.
