Chicagoland Fall Open: Player Analysis & Data Dive


By: Illinois Scouting Staff

On Wednesday, September 25th, the Prep Baseball Illinois Staff hosted the Chicagoland Fall ID at Ozinga Field in Crestwood, IL. This event, though smaller in number, was very talented and gave our staff a good look at some prospects in the area. 

Today, we will be highlighting some of the standouts from the event, followed by scouting reports on every player that was in attendance and some of the data we collected thanks to our tech partners. 

A couple uncommitted seniors to know from the day are 1B Danny Mackey III (Lincoln-Way East) and OF Monroe Evans (Morgan Park).

Mackey is a 6-foot-5, 175-pound right-handed hitting first baseman with his best days still ahead of him. He has a loose, easy swing that can lift the ball with ease to his pull-side, staying balanced throughout his operation and through impact. Throughout his round of BP, he reached up to 90.1 mph for his max EV while also reaching up to 344’ for his max distance. Steady defender at first, soft hands with confident actions. 

Evans put up some highly intriguing metrics throughout his round of BP, and he’s a twitchy prospect to know moving forward. The right-handed hitter’s BLAST metrics were off the charts for his age, averaging 24.6 mph for his hand-speed, 82.2 mph for his bat-speed and 28.4 Gs for his rotational acceleration. He took intentful swings throughout his round of BP while looking to elevate mostly to his pull-side, was on the barrel with loud contact throughout, reaching up to 98.2 mph for his max EV with an average of 90 mph, also maxing out at 377’ for his distance. He’s a clean mover in the outfield with steady actions, topping out at 84 mph from a crow hop. Corner outfield profile, 7.37 runner. 

SS Brady Holland (Mount Carmel, 2026) looked to be one of the top prospects in attendance. Listed at 5-foot-11, 162-pounds, Holland is an above-average defender on the dirt with athletic actions and soft hands, boasting a clean glove with feel for the position (T84 mph INF). The right-handed hitter has a quick, direct swing that works to stay on top of the baseball, compact operation that stays balanced throughout, uses the whole field and showed the ability to drive the ball to the opposite field gap. 7.09 runner in the 60. 

INF Howie Porath (Minooka, 2027) is a young left-handed hitter that stood out with a polished round of BP. Listed at 5-foot-10, 171-pounds, he has a proportionate and athletic frame that should continue to trend upwards in the coming years. He has an easy, simple swing that works on top of the baseball, uses the whole field with ease and can also lift to his pull-side, maxing out at 92.5 mph for his max EV. 

INF Matthew Saliers (Lane Tech, 2027) was another sophomore that showed well from the day. The right-handed hitter displayed a flat path through the zone with some bat-speed, driving the ball the other way and taking pitches on the inner-half to his pull-side, covering the plate with ease. He was on the barrel with authority throughout his round, topping out at 94.6 mph for his EV. Steady defender on the infield with a one-hand gather, confident in his hands, plays with some rhythm.

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.

MAX FASTBALL VELOCITY & AVERAGE SPIN RATE

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

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.”

AVERAGE CURVEBALL & SLIDER SPIN RATE

AVERAGE CHANGEUP HORIZONTAL MOVEMENT

MAX & AVERAGE EXIT VELOCITY

MAX DISTANCE

SWEET SPOT %

Sweet Spot percentage: This metric is determined by how often the player produces a batted ball during the session with a launch angle between 8 to 32 degrees. Sweet spot percentage can be used in concert with hard-hit rate -- the percentage of a player's batted balls that have an exit velocity of 90 mph or higher. Per MLB glossary.

BLAST MOTION

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

HAND SPEED (PEAK & AVERAGE)

Hand Speed: The observed 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 (PEAK & AVERAGE)

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)

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 %

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%.
