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.

RHP Graydon Leonard (Gibson-City Melvin-Sibley, 2027) is a young arm to watch moving forward. He has plenty to project on in his wiry 6-foot-1, 172-pound frame, and he is able to repeat his delivery and high ¾ release. His fastball played easy out of the hand in the 82-83 mph range with some carry traits and feel around the zone. To pair off the fastball he went to a curveball in the 70-72 mph range, flashing spin over 2,300 rpm and depth. His changeup has developing action and feel, but it plays clean out of the hand with some fade, 77-78 mph.
Positional Profile: RHP/SS
Body: 6-1, 172 pounds. Long-limbs, plenty more fill to come, highly projectable.
Hit: RHH. Wide setup, smooth load, toe-tap stride. Balanced, repeatable swing, on time and on the barrel. Worked gap-to-gap throughout. 61.8 mph bat speed with 4g of rotational acceleration.
Power: 83 mph max exit velocity (78.6 avg.); 248-foot max batted distance.
Arm: RH. INF - 79 mph. athletic, loose, ability to vary, primary 3/4 slot.
Defense: Patient, stays behind the ball, soft hands, athletic.
Athletic Testing: 7.36 runner in the 60-yard dash; 22.80-inch max vertical jump.
Vizual Edge: 77.81 Edge Score.
Positional Profile: RHP/SS
Body: 6-1, 172-pounds. Wiry, athletic build with room to add strength.
Delivery: Easy and simple delivery, repeats, slightly up-tempo, medium balance point, tall/fall, works in-line.
Arm Action: RH. Medium arm circle out of the glove, high 3/4 release.
FB: T83, 82-83 mph. Easy out of the hand, some carry traits. T1954, 1623 average rpm.
CB: 70-72 mph. Sharp 11/5 bite, developing control but flashed sharp action. T2314, 2119 average rpm.
CH: 77-78 mph. Clean out of the hand with feel, fading action. T1548, 1516 average rpm.
Possessing a slim 6-foot-2, 165-pound frame with a long lower half, Graydon Leonard dominated on the bump against the Illinois Gators. The righty threw five innings only allowing one run and three hits while striking out five. Mechanically, Leonard is tall on the mound with a medium leg kick and long stride striding toward the right-handed batter’s box. He throws with a 3/4 arm slot. Leonard’s loose mechanics make his pitching look effortless. He displays a 78-80 mph fastball which topped 82, with the ability to hit all the corners in addition to a 65-67 mph curveball. In addition to pitching, Leonard is impressive at the plate too. With loose mechanics that make his swing look effortless, Leonard keeps all his weight on his back leg displaying a long stride and quick hands that drive through the ball.
