South Suburban Open: Data Dive


Kevin Cronin
Tech Analyst, Area Scout

Last week, we hosted 20 prospects at the South Suburban Open at Ozinga Field. We previously broke down some of the top prospects in attendance inside of our Takeaways & Statistical Analysis story, and today we're diving even deeper into the data by examining each of the tech tools we had on-site to assist us in our player evaluations. Inside this piece, we'll take you through TrackMan, Blast Motion, and Vizual Edge findings to help identify the players who stood out to our state-of-the-art technology.

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

Rank Name State School Class Pos Velocity (max)
1 Jaryd Vence IL Hampshire 2024 RHP 84.4 mph
2 Morgan Kosmos IL Tinley Park 2024 SS 83.3 mph
3 William Glenn IL Barrington 2023 RHP 81.8 mph

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 CURVEBALL & SLIDER SPIN RATE

Rank Name State School Class Pos Spin Rate (avg)
1 William Merz IL Hinsdale Central 2024 RHP 2125 rpm
2 Morgan Kosmos IL Tinley Park 2024 SS 2059 rpm

3 Morgan Kosmos IL Tinley Park 2024 SS 13.4
4 William Merz IL Hinsdale Central 2024 RHP 12.4

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.”

Rank Name State School Class Pos HM (avg)
1 William Merz IL Hinsdale Central 2024 RHP 24.0

4 AJ (Anthony) Marchetti IL Wheeling 2023 C 91.3 mph
5 Jack Hughes IL Evergreen Park 2024 3B 88.2 mph

Exit Speed: Also according to TrackMan’s own website: “The speed of the ball, measured in miles per hour, as it comes off the bat at the moment of contact.”

Peak Estimated Batted Distance (Hitting)

Rank Name State School Class Pos Distance (max)
1 Vinnie Marvucic IL Niles North 2023 OF 359 ft
2 Jaden Franckowiak IL Andrew 2024 1B 353 ft

4 Nick Randell IL Hampshire 2024 OF 338 ft
5 Jack Hughes IL Evergreen Park 2024 3B 323 ft

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 Hand Speed (max)
1 AJ (Anthony) Marchetti IL Wheeling 2023 C 25.0 mph
2 Jake Trezise IL Lincoln-Way East 2025 OF 24.6 mph
3 Morgan Kosmos IL Tinley Park 2024 SS 23.7 mph
4 Vinnie Marvucic IL Niles North 2023 OF 23.4 mph
^ Nick Randell IL Hampshire 2024 OF 23.4 mph
5 Jaden Franckowiak IL Andrew 2024 1B 23.1 mph
6 Sean Doyle IL Andrew 2025 RHP 22.3 mph

Rank Name State School Class Pos Hand Speed (avg)
1 AJ (Anthony) Marchetti IL Wheeling 2023 C 23.5 mph
2 Nick Randell IL Hampshire 2024 OF 22.5 mph
3 Vinnie Marvucic IL Niles North 2023 OF 22.5 mph
4 Jake Trezise IL Lincoln-Way East 2025 OF 22.2 mph
5 Jaden Franckowiak IL Andrew 2024 1B 21.9 mph
6 Morgan Kosmos IL Tinley Park 2024 SS 21.0 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 Nick Randell IL Hampshire 2024 OF 72.6 mph
2 Morgan Kosmos IL Tinley Park 2024 SS 72.1 mph
3 Vinnie Marvucic IL Niles North 2023 OF 70.9 mph
4 AJ (Anthony) Marchetti IL Wheeling 2023 C 69.4 mph
5 Jaden Franckowiak IL Andrew 2024 1B 66.6 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 (Peak & Average)

Rank Name State School Class Pos Rot. Acc (avg)
1 AJ (Anthony) Marchetti IL Wheeling 2023 C 21.4 g
2 Vinnie Marvucic IL Niles North 2023 OF 20.8 g
3 Jake Trezise IL Lincoln-Way East 2025 OF 19.7 g

Rank Name State School Class Pos Bat Speed (max)
1 Nick Randell IL Hampshire 2024 OF 76.4 mph
2 Morgan Kosmos IL Tinley Park 2024 SS 75.5 mph
3 Vinnie Marvucic IL Niles North 2023 OF 74.6 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.

Vizual Edge

Take a look at the top Vizual Edge scores from the event, an assessment in visual skills from an athletic perspective.

EDGE SCORE

Rank Name State School Class Pos Edge Score
1 Michael Roberson III IL Providence Catholic 2024 C 81.86
2 Mario Recio IL UIC College Prep 2023 SS 77.04
3 Jake Trezise IL Lincoln-Way East 2025 OF 75.40
4 Aidan McGovern IL Mount Carmel 2025 1B 74.82
5 AJ (Anthony) Marchetti IL Wheeling 2023 C 73.31

The Edge Score is a comprehensive score out of 100 that takes the core-six visual skills into account, providing athletes, parents, coaches and scouts with a benchmark number for assessing an athlete’s overall visual ability. In general the higher the Edge Score, the higher chance of athletic success. Think of the Edge Score as the 'Sixth Metric' in the standard Five-Tools that make up a ball player.

The average Edge Score for the 2020 MLB Draft Class was 79.3 (of hitters who completed a Vizual Edge test). MLB players we've worked with typically show stronger scores, with elite hitters scoring consistently above 87.0 on their Edge Score.
