Fall Upperclass: Blast Motion Board


Paul Panaccione
Arizona Scouting Director

On Sunday, Oct.17, the annual Fall Upperclass Showcase was hosted at Grand Canyon University. An open event for class of 2022 and 2023 graduates in Arizona. Talents were on display in front of the PBR Arizona staff, while data was being recorded by state-of-the-art technology. 

Today, we take a look at the data recorded for hitters on Blast Motion sensors. Our Blast Analysis contains data such as: hand speed, bat speed, rotational acceleration, and on plane efficiency.

Hand Speed (Peak & Average)

Rank Name State School Class Pos Hand Speed (max)
1 AJ Nava AZ Thunderbird 2022 2B 29.6 mph
2 Jack Ellsworth AZ Highland 2022 RHP 27.2 mph
3 Max Slavin CO Rock Canyon 2022 OF 26.3 mph
4 Ruben Villaescusa AZ Tucson 2022 OF 25.5 mph
5 Dante Turgeon AZ Benjamin Franklin 2022 1B 25.4 mph

Rank Name State School Class Pos Hand Speed (avg)
1 Max Slavin CO Rock Canyon 2022 OF 24.7 mph
2 Jack Ellsworth AZ Highland 2022 RHP 24.1 mph
3 Ruben Villaescusa AZ Tucson 2022 OF 23.8 mph
4 Wyatt Graham AZ Mountain Pointe 2023 C 23.1 mph
5 Dante Turgeon AZ Benjamin Franklin 2022 1B 23.1 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 (Peak & Average)

Rank Name State School Class Pos Bat Speed (max)
1 Max Slavin CO Rock Canyon 2022 OF 80.5 mph
^ Dante Turgeon AZ Benjamin Franklin 2022 1B 80.5 mph
2 Jack Ellsworth AZ Highland 2022 RHP 80.3 mph
3 Wyatt Graham AZ Mountain Pointe 2023 C 78.3 mph
4 Jake Willerup AZ Higley 2022 OF 76.5 mph
5 Ruben Villaescusa AZ Tucson 2022 OF 76.0 mph

Rank Name State School Class Pos Bat Speed (avg)
1 Max Slavin CO Rock Canyon 2022 OF 76.6 mph
2 Dante Turgeon AZ Benjamin Franklin 2022 1B 76.2 mph
3 Ruben Villaescusa AZ Tucson 2022 OF 73.4 mph
4 Wyatt Graham AZ Mountain Pointe 2023 C 73.0 mph
5 Jake Willerup AZ Higley 2022 OF 71.6 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 (max)
1 Dante Turgeon AZ Benjamin Franklin 2022 1B 29.1 g
2 Hunter Cline AZ Desert Vista 2023 C 23.7 g
3 Wyatt Graham AZ Mountain Pointe 2023 C 23.3 g
4 Gabriel Torres AZ Mountain Pointe 2022 2B 22.8 g
5 Max Slavin CO Rock Canyon 2022 OF 22.3 g

Rank Name State School Class Pos Rot. Acc (avg)
1 Dante Turgeon AZ Benjamin Franklin 2022 1B 20.2 g
2 Gabriel Torres AZ Mountain Pointe 2022 2B 19.5 g
3 Hunter Cline AZ Desert Vista 2023 C 19.1 g
4 Marshall Mastrantuono AZ Sunnyslope 2022 SS 18.8 g
5 Max Slavin CO Rock Canyon 2022 OF 18.6 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.

On Plane Efficiency

Rank Name State School Class Pos On Plane Eff (avg)
1 Matthew Ramsdell AZ Eastmark 2022 SS 89 %
2 Max Slavin CO Rock Canyon 2022 OF 83 %
3 Logan Miller AZ Salpointe Catholic 2023 C 80 %
4 Logan Schminke AZ Thunderbird 2023 1B 79 %
5 Dylan Moir AZ Estrella Foothills 2023 C 79 %

On-Plane Efficiencyhow consistently a player maintains their arm and wrist throughout the swing, or the percentage of the swing where the bat is on-plane.
