BAWS Uncommitted: Blast Leaderboard


Blaine Clemmens
Northern California Director

LATHROP, CALIF. - Bay Area World Series Uncommitted, officially scouted by PBR Northern California, was held last Saturday (9/17/22) at Islanders Field and the event had some highly talented 2023 players still looking for a home. Today is the piece highlighting Blast Motion metrics/data. Be on the lookout for the Quick Hits piece which will highlight some of the top performers at the event.

BAWS Uncommitted Full Stats, Blast Motion, & TrackMan Data

One of the important tools Prep Baseball Report has implemented at its events and officially scouted 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 are able to collect data from each swing taken by the players. 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.

BLAST MOTION LEADERS

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

AVERAGE BAT 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%

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

AVERAGE HAND SPEED

AVERAGE 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
