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.

Positional Profile: LHP/OF 2027 LHP who will throw harder. Solid delivery showing some arm speed. FB will get better, shows late action and strikes. Secondary will firm. Lot to like from this young pitcher.
Body: 5-9, 169-pounds. Solid build with strength/thickness to lower. Upper will get stronger.
Delivery: Solid delivery. Simple delivery with side straddle rocker step. Gathers on back leg, stride is on line with spin off finish.
Arm Action: LH. Full circle, works fine out of glove, hooks to bottom of arm circle. Doesn't hinder FB, some hinderance to secondary action if doesn't come out of it early enough.
FB: T82, 81-82 mph. Solid plane, some carry present up, minor tail action to arm side. Will throw harder. Solid strikes with FB. T2075, 1957 average rpm.
CB: 67-71 mph. Flashes solid action at times, occasionally lacks depth. Will improve. T1583, 1396 average rpm.
CH: 69-70 mph. Tail action, some sink present. T1821, 1761 average rpm.
