Top Tier NorCal Scout Day: Blast Leaderboard

HAYWARD, CALIF. - We ran a scout day for Top Tier NorCal last Sunday (10/30/22) at Chabot College in Hayward and today we publish the Blast Motion hitting data, which concludes the published content from the event.

One of the important tools Prep Baseball Report implements at our 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 collect data from each swing taken by each player at the event. The metrics collected/published 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 more full picture of the player to the college and professional scouts doing their research on prospects they may be interested in.

AVERAGE 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

AVERAGE 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%

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
