On Sep. 3rd, Prep Baseball Illinois traveled to McHenry County College in Crystal Lake, IL., for the McHenry County College Scout Day. The event featured over 35+ players that allowed our staff to get an inside look ahead of their 2024 season.

Below are the day’s top performers, broken down by position players and pitchers. To see a list of those that attended, click here. For all of the statistics from this event, click here.

By The Numbers

• 4 pitchers recorded a max fastball over 90 mph and 11 total over 85 mph.
• 1 batter recorded a max exit velocity over 100 mph and 8 total over 95 mph.
• 2 batters recorded a max bat speed over 80 mph and 5 total over 75 mph.

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

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.”

MAX DISTANCE (HITTING)

SWEET SPOT % (HITTING)

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 open showcase.

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 (PEAK & 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.
