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.

Luke Gremelspacher, ST THEODORE GUERIN (IN), 2026
Positional Profile: 3B/RHP
Body: 6-3, 195-pounds. Athletic, projectable frame. Still has room to fill out more.
Delivery: Moderate tempo with a compact leg lift keeping weight in back hip. Good stride distance down the mound, lands square consistently. Shoulders remain even down the slope, achieves decent shoulder separation however.
Arm Action: RH. Deceptive arm action from a 3/4 to sub 3/4 slot. Loose arm action.
FB: T80, 79-80 mph. Heavy sinker. T1977, 1882 average rpm.
CB: 70-72 mph. Slider T2306, 2274 average rpm.
SL: 70-72 mph. Effective slider movement, will tunnel off of sinker very well. T2269, 2214 average rpm.
CH: 72-74 mph. Lots of arm side movement. Similar movement profile to sinker. T1680, 1638 average rpm.
ATH: 7.83 runner in the 60.
Luke Gremelspacher, ST THEODORE GUERIN (IN), 2026
Positional Profile: 3B/RHP
Body: 6-3, 195-pounds. Athletic, projectable frame. Still has room to fill out more.
Hit: RHH. Sets up in a tall, narrow stance with open feet and hands high and tight. Load mechanism is primarily upper body as hands work back first achieving sufficient shoulder separation. Slight weight shift onto hind leg follows. Stride foot hovers forward back on plane with hips and shoulders, good hip separation. Hands remain low throughout swing, high intent swing with a fly ball, power approach. Rotational athlete with quick hands. Upper body torque responsible for majority of pop. 59.5 mph bat speed with 19 G's of rotational acceleration.
Power: 86 max exit velocity, averaged 78.9 mph. 303' max distance.
Arm: RH. INF-79 mph. Quick, loose arm action from a 3/4 to sub 3/4 arm slot. Shoulder separation in throw is promising.
Defense: Smooth footwork for big frame, very confident in glove. Moderate ball to hand ability.
ATH: 7.83 runner in the 60.
