Norcal Underclass Games: Blast Motion Leaderboard


PBR CA Scouting Staff

New Episode LIVE now! At The Yard Podcast

ISLANDERS FIELD - LATHROP, CALIF. - A total of 39 position players, all uncommitted, came out for the morning showcase/testing session. The event was all 2024/2025 grads, with a number of players who will appear in future rankings in attendance.

In addition to the traditional showcase (60 yard run, BP round, defensive workouts), the pitchers competed in live game action where their data was gathered, and each position player had four at-bats during the game they played in. Today's post highlights the leaders in four Blast Motion categories.

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. The metrics collected include: Bat Speed, On Plane Efficiency, Peak Hand Speed, and Rotational Acceleration. 

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.

(Note: All showcase videos have been edited and added to the players' profiles)

Peak 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

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%

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
