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
Slider
Hammer+
A hammer breaking ball drops vertically with velocity through the zone, or 12-to-6 movement. Hammer+ of 100 is MLB average.
Slider
Sweep+
A sweeping breaking ball moves horizontally with velocity through the zone. Sweep+ of 100 is MLB average.
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.

Cooper Hershenhorn, Team Ontario Astros, 2027 (No. 107) Uncommitted
Positional Profile: OF/LHP
Body: 6-0, 172-pounds.
Hit: LHH. 31% Sweet Spot%, 25% Line Drive%, 31% Flyball%.
Power: 93.5mph max exit velocity, averaged 84.6mph. 303ft max distance, averaged 176ft. 19% Hard-Hit%.
Arm: LH. OF - 86mph.
ATH: 4.11 runner in the 30-yard, 1.76 10-yard split.
Lots to like from the 5-foot-11, 167-pound two-way out of the Astros system. Strong for his class and looks right in the box from the left-side. Middle of the order type bat with some legitimate pop. Furthermore, Cooper is a promising southpaw that moves well downhill, attacks from more of a 3/4 slot, and shows feel for the whole arsenal. He will be a name to monitor in the years to come and has the potential to make some serious noise when it is all said and done.
