SoCal Upperclass ID: Blast Motion Analysis

New Episode LIVE now!-At The Yard Podcast

At the recent SoCal Upperclass ID Camp players were set up with a Blast Motion sensor before each round of batting practice. 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, Power 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.

Many of the players in the upperclass event were uncommitted and many of them put up some very good numbers, below we illustrate the top 25 players in each category.

Category Leaders

Max Bat Speed: Julian Eskridge (Arcadia HS) - 82 mph

Peak Hand Speed: Sam Purgason (Truckee HS) - 26.09 mph

On-Plane Efficiency: Kaleb Duran (Summit HS), Joey Fonseca (El Diamante HS) - 87%

Avg. Rotational Acceleration: Anthony Beau Manuel (Gahr HS) - 37.6 g

Power: Bryce Gamble (El Dorado HS) - 5.24 kW

CATEGORICAL LEADERBOARDS

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 | MiLB: 63-75 mph | College: 66-75 mph

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

MLB Avg: 23-29 mph | MiLB Avg: 22-28 mph | College Avg: 21-24 mph

Avg. 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%

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 | MiLB Avg: 12.6 g | College Avg: 12.9 g

Power

The average Power generated during the swing is found from the effective mass of the bat, the Bat Speed at impact, and the average acceleration during the downswing. Power is measured in Watts. Higher Power is achieved when a hitter is able to swing a heavier bat and accelerate it to higher speeds. For more info: Power

MLB Avg: 3.65-5.65 kW | MiLB Avg: 3.20-5.20 kW | College Avg: 3.83-5.08 kW
