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.

Greyson Mazza: 3B/OF, (2026) Xaverian Brothers, MA. 155-pound athletic lean frame. Projectable at the plate, Mazza recorded an exit velocity of 80 mph. (62.3 mph bat speed average). (19.1 mph hand speed average). Started in a closed wide stance with a controlled load, then used a small stride. Bat speed is developing and quick, uses a loose flat swing plane and good extension on his finish. He barreled up multiple balls during the round. Gap to gap approach. Projectable in the outfield, his best throw of the day was clocked at 84 mph; had a natural exchange, developing soft hands, and developing consistent footwork. Fields the ball to the side, movements laterally were athletic. Used a high ¾ slot and a quick arm action while showing consistent accuracy to the base. Projectable on the mound, showed a ¾ arm angle and a loose consistent arm action with quick developing arm speed. Feel type pitcher who shows some effort. Displays in line shoulders and a consistent balance point. Lands closed with a falling off finish. Threw his fastball 81-82 mph; had running sinking action and command arm side around the zone. (Max spin 2011; Avg 1910). Showed sweeping action and glove side some command on his curveball (66-67). (Max spin 1873; Avg 1842). His changeup (74-75) shows arm side control and gradual fading action.
Greyson Mazza: 3B/RHP, (2026) Xaverian Brothers, MA. 5-foot-10, 150-pound lean athletic build. Raw capable at the plate, Mazza clocked an exit velocity of 75 mph. (67.9 mph bat speed average). (22.4 mph hand speed average). Begins in a balanced closed stance with a controlled load, then uses a small stride. Bat speed is developing and shows a rotational long swing plane. Through his round he found a few barrels with loud contact. Pull side approach. Raw while in the infield, recorded position velocities up to 71 mph; had firm developing hands, a natural exchange, and consistent developing footwork. Fields the ball out front, movements laterally were developing. Showed consistent accuracy to the base with a ¾ slot. Projectable on the mound, showed developing arm speed, also used a short arm action and a high ¾ arm angle. Feel type pitcher who shows some effort. Has a consistent balance point with in line shoulders. Lands closed with an athletic finish. Sat with his fastball at 74-76 mph; has running action and command arm side in the zone. (Max spin 1903; Avg 1726). Threw a tight curveball (62-64) that showed sweeping action and glove side command. (Max spin 1820; Avg 1776). His changeup (68-69) has gradual fading action and arm side feel command.
