Top Prospect Games Underclass: Blast Motion Board

On Tuesday, June 7, the PBR Missouri staff traveled to Atkins Field in Columbia, MO, to host the Top Prospect Games: Underclass event. Formerly touted as the MO Underclass Games, this invite-only event featured more than 60 names representing the 2024-to-2026 grad classes across the entire ‘Show Me’ state. Those in attendance will participate in a pro-style workout to begin the event, followed by live game action.

Earlier this week we published a Statistical Analysis, bringing you a quick look at the stat leaders of those that participated in the event. We then dove deep into the data, looking at the pitch metrics and batted ball numbers from this event inside our TrackMan Files piece.

Today, with the help of our Blast Motion sensors, we're analyzing the swing metrics measured from Tuesday's invite-only event.

1 Jake Ryan MO Father Tolton 2024 RHP 24.8 mph
2 Carson Ramos MO Timberland 2025 C 22.9 mph
3 Charlie Isom-McCall MO St. Louis University 2024 SS 22.2 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 Carter Cox MO Fort Zumwalt South 2024 LHP 74.4 mph
2 Carson Ramos MO Timberland 2025 C 74.0 mph
3 Dean Lyon MO Saint Louis University 2024 SS 73.7 mph
4 Jackson Engel MO Moberly 2025 SS 73.4 mph
5 Harrison Lear MO Blair Oaks 2024 RHP 73.0 mph
6 Crew Norden MO Rock Bridge 2025 C 71.8 mph
7 Jake Ryan MO Father Tolton 2024 RHP 71.3 mph
8 Ryker Benz MO Vianney 2025 3B 71.1 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 (max)
1 Eric Williams MO Fort Zumwalt East 2024 SS 30.0 g
2 John Spivey MO St. Louis Priory 2024 OF 25.3 g
3 Charlie Isom-McCall MO St. Louis University 2024 SS 21.3 g
4 Ryker Benz MO Vianney 2025 3B 21.0 g

Rank Name State School Class Pos Rot. Acc (avg)
1 Eric Williams MO Fort Zumwalt East 2024 SS 22.2 g
2 John Spivey MO St. Louis Priory 2024 OF 19.1 g
3 Charlie Isom-McCall MO St. Louis University 2024 SS 17.7 g
4 Ryker Benz MO Vianney 2025 3B 16.3 g

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.
