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.

Heisl came on as a surprise in a starter’s role for his team, standing at a wiry and projectable 6-foot, 150-pound frame. The right-hander topped out at 85 mph with the fastball, sitting between 82-84 mph throughout his four-inning start. The uncommitted prospect only allowed one hit, flipping up a 12/6 curveball that earned consistent swings and misses. Heisl’s two-pitch mix was noteworthy, raising his stock as a pitcher as he enters his senior year in the fall.
Heisl stands a projectable 6-foot, 150 pounds with an athletic frame. His delivery shows good movement patterns with proper sequencing between his lower and upper half. His fastball topped out at 84 mph with high spin metrics (2583 RPM’s) on the pitch. His 70-71 mph curveball has an alarming 3000 RPMs with 10/4 shape and break at the plate. His slider featured huge sweeping action and spun at an astonishing 2900 RPM’s. The ability to spin the baseball with both the fastball and his secondary weapons has put Heisl firmly on the list of names to know in the state going forward.
Positional Profile: RHP/SS
Body: 6-0, 150-pounds.
Delivery: Deliberate side step into a high leg-lift, drop/drive lower-half stride works in-line.
Arm Action: RH. Long out of the glove into a high 3/4 slot.
FB: T84, 81-83 mph. Carry through the zone with feel. T2583, 2338 average rpm.
CB: 70-71 mph. Sharp with a late break, can really spin it. T3058, 2973 average rpm.
SL: 70-71 mph. Similar to the curveball with more lateral break, can really spin it. T3047, 2895 average rpm.
