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.

Grip Strgth (LH)
Grip strength is a measure of a players bat control and ability to transfer power and speed during impact, measured in pounds of force generated; collected with elbow bent at 90 degrees.
Grip Strgth (RH)
Grip strength is a measure of a players bat control and ability to transfer power and speed during impact, measured in pounds of force generated; collected with elbow bent at 90 degrees.
6-foot-2, 170-pound right-handed pitcher and right-handed hitting corner infielder. On the mound, the delivery is quick in tempo and the arm is extremely quick. The fastball sat in the low 90's and he flashed the makings of an above average slider. Defensively, the glove and feet work well in the infield. He threw 90 mph across the diamond. The bat had an exit velocity of 98 mph. The hands work freely and the path is flat to contact.
6-foot-3, 170-pound corner infielder and right-handed pitcher. He ran a 6.75 sixty at the event. The skill set at third is solid as he moves through the baseball as he fields it. The arm is special, throwing 89 mph across the diamond. The bat had an exit velocity of 95 mph. The setup at the dish was even in base and the front foot gains ground to the baseball. The path is flat and long to contact. On the mound, the delivery is solid in tempo and repeated. The fastball was 88-89 mph with good life. He showed the makings of a power breaking ball at 73-74 mph. The changeup showed fade and sink. It would not surprise me if he was pitching in the low to mid 90's next season as his arm is very quick.
