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.

Lake Land commit. Ranked No. 289 in the state. Ultra-projectable, 6-foot-2, 150-pound frame, long levers. Loose, whippy arm on the mound, worked his fastball up to 84 mph, sitting 81-83 mph with heavy sink to the arm-side. Went to a sharp 11/5 breaking ball at 69-70 mph with some feel for the zone. Was dominant over his six innings of work, allowing just one hit, two earned runs and striking out eight.
RHP Taylor Siekierski (Fenton, 2023) stands 6-foot-2, 140-pounds with all sorts of room to add strength to his projectable frame. His limbs are long and loose, producing a fastball up to 84 mph with slight sinking action. His breaking ball plays with sharp 11/5 action with swing-and-miss potential at 72-75 mph. His third and final offering was a sinking changeup at 77-79 mph, coming from an identical fastball slot with arm-speed.
Positional Profile: RHP
Body: 6-2, 140-pounds. Long-levered, highly-projectable build.
Delivery: Athletic delivery, high leg-kick into a drop/drive lower-half, works in-line to the plate with a long stride. In-game stats: 2 IP, 1 H, 1 K, 0 BB, 0 R
Arm Action: RH. Short out of the glove into a loose 3/4 release, quick arm.
FB: T84, 82-84 mph. Life through the zone with slight running action. T2095, 2028 average rpm.
CB: 72-75 mph. 11/5 shape with feel for the zone, flashed sharp action. T2354, 2203 average rpm.
CH: 77-79 mph. Feel for the zone, plays with fading action, maintains arm-speed. T1663, 1546 average rpm.
Positional Profile: RHP/SS
Body: 6-2, 142-pounds.
Delivery: Worked exclusively from the stretch, drop/drive lower-half that works athletically down the mound, long stride that remains in-line to the plate.
Arm Action: RH. Loose/quick arm, long arm circle out of the glove that moves into a 3/4 slot, extremely whippy.
FB: T81.2, 80.2-80.9 mph. Natural arm-side life, some ride through the zone. T1676, 1456 average rpm.
CB: 70.1-71.0 mph. Short 11/5 break, thrown with intent. T2060, 2014 average rpm.
CH: 75.2-76.4 mph. Thrown with intent, dives to the arm-side. T1251, 1184 average rpm.
