North Bay Open: Blast Motion Leaderboard

New Episode LIVE now! At The Yard Podcast

YOUNTVILLE, CALIF. - The event was held at historic Borman Field, on the premises of the Veteran's Home of California in the heart of scenic Napa Valley. Nearly 30 players came out to the open event, many showcasing themselves for the first time. The event was heavy on 2023/2024 grads, with a couple of talented 2022s in attendance and a 2025 sure to draw plenty of attention in the coming years.

As an open event, this was conducted as a straight traditional showcase, 60 yard run, BP round, defensive workouts and pitchers ending the day on the mound throwing 15-20 pitch sessions.

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 BAWS 2021. 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.

We will roll out more data from this event in the coming days and weeks.

(Note: All showcase videos have been added to 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

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
