GPA Games: Blast Motion Board


Kevin Cronin
Area Scout

On Sunday, August 8, the PBR Illinois scouting staff hosted the annual GPA Games at Lee Pfund Stadium in Carol Stream, IL. This open event to all current high school classes featured both a workout portion and gameplay setting, allowing those in attendance to show off their skills in multiple different facets. All participants that attended were of high academic standing, as verified through registering their standardized test scores and GPAs.

Shortly after the event's conclusion we published our Quick Hits piece - a rapid analysis of those who stood out at the event. You can find that by clicking HERE. We also took a look at all the batted ball and pitch metric data from Sunday's showcase inside our TrackMan Files, which can be found HERE.

Today, with the help of our Blast Motion sensors, we're analyzing the swing metrics measured on Sunday's showcase.

Hand Speed (Peak & Average)

Rank Name State School Class Pos Hand Speed (max)
1 Zander Tubbs IL Plainfield South 2022 OF 25.7 mph
2 Tyler Hofmann WI Germantown 2022 C 25.1 mph
3 Evan Blackman IN Brebeuf Jesuit 2023 2B 25.0 mph
4 Alexander Cabrera IL IMG Academy 2022 3B 24.6 mph
^ Calvin Keesler WI Xavier 2022 OF 24.6 mph
5 Joey Scaravalle IL Crystal Lake Central 2022 OF 24.3 mph

Rank Name State School Class Pos Hand Speed (avg)
1 Zander Tubbs IL Plainfield South 2022 OF 23.6 mph
2 Joey Scaravalle IL Crystal Lake Central 2022 OF 23.2 mph
3 Tyler Hofmann WI Germantown 2022 C 23.1 mph
4 Calvin Keesler WI Xavier 2022 OF 23.0 mph
5 Evan Blackman IN Brebeuf Jesuit 2023 2B 22.4 mph
6 Isaiah Hernandez IL De La Salle 2022 C 22.2 mph
7 Ethan Chance IL Plainfield South 2022 OF 21.5 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 Tyler Hofmann WI Germantown 2022 C 69.9 mph
2 Jerome Pawlak WI Germantown 2022 OF 69.4 mph
3 Joey Scaravalle IL Crystal Lake Central 2022 OF 68.7 mph
4 Zander Tubbs IL Plainfield South 2022 OF 67.1 mph
5 Ryan Procajlo IL York 2023 3B 67.0 mph
6 Isaiah Hernandez IL De La Salle 2022 C 66.5 mph
7 Evan Blackman IN Brebeuf Jesuit 2023 2B 66.4 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 (Peak & Average)

Rank Name State School Class Pos Rot. Acc (max)
1 Joey Scaravalle IL Crystal Lake Central 2022 OF 32.2 g
2 Zander Tubbs IL Plainfield South 2022 OF 31.3 g
3 Harout Meyer IL Huntley 2022 RHP 28.9 g
4 Tyler Hofmann WI Germantown 2022 C 23.1 g

Rank Name State School Class Pos Rot. Acc (avg)
1 Joey Scaravalle IL Crystal Lake Central 2022 OF 29.8 g
2 Zander Tubbs IL Plainfield South 2022 OF 25.0 g
3 Tyler Hofmann WI Germantown 2022 C 20.1 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.
