Underclass Trials: Blast Motion Board
July 8, 2021
On Wednesday, June 23, the PBR Wisconsin staff hosted the Underclass Trials, our first showcase of the summer in the Badger State and an annual staple on our calendar. This open event served as an identifier to all members of high school classes 2023-25, serving as an up-close look for future invite-only events, like the PBR Future Games, among others.
Earlier today we published our TrackMan findings, and we published the traditional stats leaderboard earlier in the week with added analysis on more of the event's top performers.
Today, with the help of our Blast Motion sensors, we're analyzing the swing metrics measured at this open event.

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 | D'Angelo Rivera | WI | Waukesha North | 2024 | 1B | 73.5 mph |
2 | Landon Dessart | WI | Union Grove | 2024 | RHP | 71.3 mph |
3 | Luke Heinkel | WI | Brookfield East | 2023 | 1B | 70.8 mph |
4 | Zachary Kiffmeyer | WI | Oshkosh North | 2025 | RHP | 69.0 mph |
5 | Easton Harris | WI | Middleton High School, WI | 2025 | LHP | 68.5 mph |
6 | Eli Becker | WI | Homestead | 2024 | C | 68.3 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 | Sawyer Deering | WI | Kimberly | 2025 | RHP | 28.4 g |
2 | Brandon Bates | WI | Seymour | 2024 | RHP | 25.3 g |
3 | Luke Heinkel | WI | Brookfield East | 2023 | 1B | 23.7 g |
4 | Zachary Kiffmeyer | WI | Oshkosh North | 2025 | RHP | 23.2 g |
5 | Johnny Leaver | WI | La Crosse Logan | 2024 | OF | 22.7 g |
6 | Leo Weist | WI | Union Grove High | 2025 | C | 21.9 g |

5 | Zachary Kiffmeyer | WI | Oshkosh North | 2025 | RHP | 18.1 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.
