Prep Baseball was at the American Dream Facility in Fuquay-Varina for a Scout Day with ZT Prospects.  ZT Prospects, formerly known as American Dream Baseball, is a young and upcoming program, drawing talent from around the Triangle area.  This scout day featured players from the ZT Prospects as well as a handful of players outside of the organization that the ZT Prospects allowed to workout during the Scout Day.

The day started with players running a laser timed 30 and 60.  Ten yard splits were taken off of each run, giving players some feel for their start and their split interval times and speeds.  From there hitters took multiple rounds of BP with TrackMan tracking each ball put in fair play.  After the offensive evaluations, players were evaluated at their primary defensive positions.  To finish the day, pitchers threw controlled bullpens, again with TrackMan tracking each pitch and giving analytic data on each player.

Below we begin to break down the player performances from the workout.  To see the full roster with all of the stats from the workout, you can CLICK HERE.

FASTBALL STATS

Peak Velocity

Rank Name State School Class Pos Velocity (max)
1 Cassius Grimsley NC Fuquay-Varina 2026 OF 85.0 mph
2 Cason Pope NC South Johnston High 2026 RHP 82.1 mph

4 Kason Brown NC Triton High 2026 RHP 78.0 mph
5 William Fansler NC Willow Spring High 2028 RHP 74.6 mph


Average Effective Velocity

Effective velocity is taking into account the velocity of each pitch, its release distance, the pitches time to the plate / hitting area, and the pitches movement.  With all of this information, Effective Velocity is allowing coaches and scouts to more accurately compare how a pitch is affecting a hitter.

Rank Name State School Class Pos Eff Velocity (avg)
1 Cassius Grimsley NC Fuquay-Varina 2026 OF 82.9 mph

4 Austin Tew NC West Johnston High 2028 OF 1821 rpm
5 Cassius Grimsley NC Fuquay-Varina 2026 OF 1770 rpm


Average Induced Vertical Movement

Induced vertical movement tracks how the ball rides through the zone, or sinks through the zone.  For the purpose of this board we are tracking which fastballs showed the most ride, typically leading to more swing and miss opportunities

4 Cason Pope NC South Johnston High 2026 RHP 15.2 in
5 Thurman Thomas NC Willow Springs 2028 OF 14.4 in


Average Horizontal Movement

Horizontal movement is often referred to as run.  This measurement does not distinguish between early and late movement, just the overall amount the ball tracks to the arm side out of the hand.

Rank Name State School Class Pos HM (avg)
1 Cassius Grimsley NC Fuquay-Varina 2026 OF -17.9

4 William Fansler NC Willow Spring High 2028 RHP -5.9
5 Joshua Rosser NC WAKE CHRISTIAN ACADEMY 2028 1B -5.9


Peak Spin Score

The Spin Score is a measurement linking velocity and spin.  It is calculated by dividing the spin rate by the velocity of each pitch.

Average Induced Vertical Movement

This is a measurement of how much the ball drops from its original position and trajectory.  It does not measure how late the movement happens.  This can be referred to as depth on a breaking ball.
