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.

Uncommitted. Listed at 5-foot-7, 148-pounds with athleticism and some present strength. Started at second base and batted third. Showed a quality look from the left-side of the plate, simple, fluid load with control and balance throughout. Hands stay short to the barrel with ease and minimal effort. Finished the day with one hit, driving a ball on the outer half to the opposite field for an RBI single. He’s a confident defender on the infield with clean actions and sure hands. An uncommitted name that continues to impress this spring for a talented Monticello team.
Started at second base and batted second for Monticello. Was the spark plug for the Sages’ offense, blasting a two-run home run in his first at-bat of the game; finished the game 2-for-4 with a home run, double, three RBIs and two runs scored. A left-handed hitter, Williams has a quality look in the box; fluid load that stays tall through contact, slightly uphill bat path. Showed quality speed rounding the bases on his double, and showed clean/fluid defensive actions up the middle. A name-to-follow throughout the rest of his prep career.
