LATHROP, CALIF. - One of the important tools Prep Baseball Report has implemented at its events is the use of Blast Motion sensors. During batting practice, the Blast Motion sensors measure Swing and Impact Metrics across several categories. Swing metrics measure pre-impact mechanics centered around plane, connection, and rotation while impact metrics measure pre-impact performance outcomes based on ball contact.
With the Blast Motion sensor, we were able to collect data from each swing taken by each prospect at the event. Some of the metrics collected include: Bat Speed, On Plane Efficiency, Peak Hand Speed, Power and Rotational Acceleration. Those metrics are published in this piece.
Each player has their Blast Motion metrics uploaded into their profiles following the completion of the event providing insight into areas that could be improved upon as well as helping paint a clear picture of the player to the college and professional scouts doing their research on prospects they may be interested in. The full list of metrics recorded are; on plane efficiency, rotational acceleration, early connection, connection at impact, bat speed, attack angle, vertical bat angle, time to contact, peak hand speed, and power kW. Each of those data points live in the players' profiles.
Many of the players in the event were uncommitted and many put up some impressive numbers, below we list the top players in four categories.
NOTE: Each player had one round of BP and upwards of 10 swings.
CATEGORICAL LEADERBOARDS
Max Bat Speed
Bat Speed is the observed speed of the sweet spot of the bat at impact. For more info: Blast Bat Speed

15 | Austin Steeves | CA | Casa Grande | 2024 | LHP | 63.7 mph |
^ | Tommy Goodin | CA | Camarillo | 2024 | 1B | 63.7 mph |
Max Hand Speed
Peak Hand Speed is 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. For more info: Peak Hand Speed
MLB Avg: 23-29 mph | College Avg: 21-24 mph | HS Varsity Avg: 19-22 mph
Rank | Name | State | School | Class | Pos | Hand Speed (max) |
1 | Justin Iglesias | CA | Bishop O'Dowd | 2024 | RHP | 24.2 mph |
2 | Justin Sechler | CA | Serra | 2024 | 1B | 22.4 mph |
3 | Daniel Solis | CA | Valley Christian | 2025 | RHP | 22.3 mph |
4 | Braden Agosta | CA | Serra | 2024 | OF | 22.2 mph |
5 | Jacob Untalan | CA | Cardinal Newman | 2024 | SS | 22.1 mph |
6 | Tatum Marsh | CA | Valley Christian | 2024 | OF | 21.6 mph |
7 | Giovanni Cadena | CA | Heritage | 2025 | RHP | 21.4 mph |
8 | Peter Krumins | CA | Piedmont | 2024 | SS | 21.3 mph |

15 | Tyler Kennedy | CA | Granada | 2025 | RHP | 20.4 mph |
Average On-Plane Efficiency
Measures the percentage of your swing where the bat is on the swing plane. Your vertical bat angle at contact establishes the plane for that swing. Plane is a great indicator for making more consistent contact on the barrel of the bat. For more info: On-Plane Efficiency
Ideal Efficiency %: 70% or Higher | Range: 65%-85%
Rank | Name | State | School | Class | Pos | On Plane Eff (avg) |
1 | Lucca Sanguinetti | CA | Archbishop Mitty | 2024 | 3B | 93 % |
2 | Jordan Hsieh | CA | Santa Teresa | 2025 | C | 87 % |

Max Rotational Acceleration
Measures how quickly your bat accelerates into the swing plane. Rotation is a good indicator of how you build bat speed by sequencing properly. The quicker your rotational acceleration, the more power you will have and the more time you have to adjust to pitch locations. For more info: Rotational Acceleration

Rank | Name | State | School | Class | Pos | Rot. Acc (max) |
