Harper JC Scout Day: Statistical and Data Analysis


Illinois Scouting Staff

On Friday, August 29th, the PB Illinois staff traveled to Harper Junior College in Palatine, IL, to host the annual Harper JC Scout Day, an open event for all members of the Harper Hawks.

More than 30 players participated in a pro-style workout, gathering unrivaled access to data through our state-of-the-art tech partners, as well as in-depth scouting analysis from our Prep Baseball Illinois staff.

Today, we will be looking at the top statistical performers from the event, found below.

TRACKMAN

We'll continue to roll out the data we gathered from this event, starting with the analytics we have at our disposal from our TrackMan units. Below we'll look at which players had noteworthy batted ball and pitch data.

MAX FASTBALL VELOCITY & AVERAGE SPIN RATE

Rank Name State School Class Pos Velocity (max)
1 David Essien IL Fremd 2023 RHP 96.1 mph
2 Gavin O'Neil IL Lake Park 2025 OF 88.6 mph
3 Zack LaBrec IL Cary-Grove 2022 RHP 86.8 mph
4 Riley Blackwell IL Hersey 2025 LHP 84.2 mph
5 Zach Zalewski IL Wheeling 2023 RHP 84.2 mph

Rank Name State School Class Pos Spin Rate (avg)
1 David Essien IL Fremd 2023 RHP 2484 rpm
2 Jonah Elvidge IL Lincolnwood 2025 SS 2320 rpm
3 Logan Sarna WI Mukwonago 2024 RHP 2185 rpm
4 Daniel Gross IL J Sterling Morton West 2025 LHP 2167 rpm
5 Gavin O'Neil IL Lake Park 2025 OF 2112 rpm

Max Fastball Velocity: This metric calculates the speed of the pitch as it’s released from the pitcher’s hand.

Spin Rate: This metric calculates the rate of spin on the baseball as it leaves the pitcher’s hand, measured in revolutions per minute (rpm). Historical data shows that high-spin fastballs lessen the impact of gravity, allowing for more ‘rise’ (or less fall, in other words) as it carries through the zone. Low-spin fastballs typically indicate the pitch has greater horizontal action, often making it tougher to square up, but generally easier to make contact with, leading to more ground balls, while high-spin fastballs show a correlation with swings and misses.

AVERAGE FASTBALL HORIZONTAL MOVEMENT

Rank Name State School Class Pos HM (avg)
1 Zach Zalewski IL Wheeling 2023 RHP 17.0
2 Riley Blackwell IL Hersey 2025 LHP -16.3
3 Evan Fahey IL Hersey 2024 2B 15.9
4 Gavin O'Neil IL Lake Park 2025 OF 13.7
5 Aaron Buckholtz IL Lyons Township 2023 LHP -12.7

Horizontal Break: Outlined on TrackMan’s own website: “... horizontal movement is measured in inches between where the pitch actually crosses the front of home plate side-wise, and where it would have crossed home plate side-wise if had it traveled in a perfectly straight line from release. A positive number means the break was to the right from the pitcher’s perspective, while a negative number means the break was to the left from the pitcher’s perspective.”

BLAST MOTION

With the help of our Blast Motion sensors, we're analyzing the swing metrics measured at this open showcase.

HAND SPEED (PEAK & AVERAGE)

Rank Name State School Class Pos Velocity (max)
1 David Essien IL Fremd 2023 RHP 96.1 mph
2 Gavin O'Neil IL Lake Park 2025 OF 88.6 mph
3 Zack LaBrec IL Cary-Grove 2022 RHP 86.8 mph
4 Riley Blackwell IL Hersey 2025 LHP 84.2 mph
5 Zach Zalewski IL Wheeling 2023 RHP 84.2 mph

Rank Name State School Class Pos Hand Speed (avg)
1 Collin Roche IL Nazareth Academy 2025 C 23.5 mph
2 Mitchell Hall IL Leo Catholic 2023 OF 22.9 mph
3 Connor Kave IL Hersey 2023 OF 22.8 mph
4 Jaxon Cook IL Springfield Southeast 2024 3B 22.2 mph
5 Will Hickey IL Hersey 2024 OF 22.1 mph

Peak Hand Speed: The observed maximum speed as measured on the handle of the bat (measured six inches from the knob of the bat). Peak Hand Speed will occur prior to the moment of impact, very close to the commit time in the swing when the wrists unhinge.

BAT SPEED (AVERAGE)

Rank Name State School Class Pos Bat Speed (avg)
1 Cooper Nelson IL William Fremd High School 2025 77.7 mph
2 Brayden Clancy IL Lake Park 2024 OF 74.4 mph
3 Peter Castaneda IL Conant 2023 OF 72.7 mph
4 Nick Drtina IL Nazareth Academy 2024 RHP 72.5 mph
5 Will Hickey IL Hersey 2024 OF 72.4 mph

Bat Speed: The observed speed of the sweet spot of the bat at impact. The sweet spot of the bat is measured six inches from the tip of the bat.

ROTATIONAL ACCELERATION (AVERAGE)

Rank Name State School Class Pos Velocity (max)
1 David Essien IL Fremd 2023 RHP 96.1 mph
2 Gavin O'Neil IL Lake Park 2025 OF 88.6 mph
3 Zack LaBrec IL Cary-Grove 2022 RHP 86.8 mph
4 Riley Blackwell IL Hersey 2025 LHP 84.2 mph
5 Zach Zalewski IL Wheeling 2023 RHP 84.2 mph

Body Rotation: A swing that has the appropriate relative contributions of body and bat rotations is an efficient and Powerful swing that maintains proper sequencing. An efficient baseball swing is one in which the body creates the initial movements, which is then transferred to the arms and out to the bat, thereby maximizing Bat Speed through this proximal-to-distal kinematic sequencing movement pattern.

ON-PLANE EFFICIENCY % (AVERAGE)

Rank Name State School Class Pos On Plane Eff (avg)
1 Owen Anderson IL Prospect 2024 OF 84 %
2 Peter Castaneda IL Conant 2023 OF 81 %
3 Kevin Geake IL Glenbrook North 2023 C 75 %
4 Jonah Elvidge IL Lincolnwood 2025 SS 75 %
5 Nick Drtina IL Nazareth Academy 2024 RHP 74 %

On-Plane Efficiency %: measures the percentage of your swing where the bat is on the swing plane. Your Vertical Bat Angle (VBA) at contact establishes the plane for that specific swing. A high % is a great indicator of making consistent contact and barreling balls. Blast recommends an average of 70% or higher, with a range in the 65% to 85%.
