NorCal Rising Stars: Blast Leaders

New Episode LIVE now! At The Yard Podcast

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 

MLB Avg: 66-78 mph | College: 66-75 mph | HS Varsity: 60-70 mph

Rank Name State School Class Pos Bat Speed (max)

3 Tatum Marsh CA Valley Christian 2024 OF 69.0 mph
4 Quinten Marsh CA Valley Christian 2025 OF 68.6 mph

15 Austin Steeves CA Casa Grande 2024 LHP 63.7 mph
^ Tommy Goodin IV CA Agoura 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)

14 Kalen Clemmens CA Casa Grande 2024 C 20.6 mph
15 Tyler Kennedy CA Granada 2025 3B 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)

14 Austin Steeves CA Casa Grande 2024 LHP 73 %
15 Michael Perazzo CA Serra 2024 SS 73 %

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

MLB Avg: 16.8 g | College Avg: 12.9 g | HS Varsity Avg: 9.9 g
