METRICS

Metrics are a huge role today in the game of baseball! When you attend a showcase I promise they are going to record some sort of metrics whether it be hitting or pitching! I personally keep metrics with Blast Motion because it allows me to see what your weaknesses are and build custom programs to attack those weaknesses while also keeping your strengths strong! Below I will explain what metrics we look at, what they are exactly defined by Blast Motion, and where your numbers should be based on your playing level!

Bat Speed

Youth: 40-56 MPH

High School: 60-70 MPH

College: 66-75 MPH

Bat Speed is the observed speed of the sweet spot of the bat at impact. The sweet spot of the bat is measured six inches from the tip of the bat.

Attack Angle

Youth: 0-15 Degrees

High School: 2-13 Degrees

College: 2-15 Degrees

Attack Angle is the angle of the bat's path, at impact, relative to horizontal. A positive value indicates swinging up, and a negative value indicates swinging down, where zero is perfectly level. 

Exit Velo

Youth: 47-66 MPH

High School: 72-84 MPH

College: 79-89 MPH

Exit Velo is the speed of the ball immediately after impact. In miles per hour. 

Launch Angle

Youth: 10-25 Degrees

High School: 10-25 Degrees

College: 10-25 Degrees

Launch angle is the angle between the ball path and the ground, measured in degrees. 

Time to Contact

Youth: .17-.23 Sec

High School: .15-.20 Sec

College: .14-.16 Sec

Time to Contact is the elapsed time between start of downswing and impact. The start of downswing uses an advanced algorithm to detect when functional forward Bat Speed is initiated and is not triggered by bat waggle early in the swing.

Peak Hand Speed

Youth: 17-23 MPH

High School: 19-25 MPH

College: 21-24 MPH

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.

 

Power

Youth: .90-2.50 kW

High School: 2.81-4.09 kW

College: 3.83-5.08 kW

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

Vertical Bat Angle

Youth: 

High School

College:

Vertical Bat Angle is angle of the bat with respect to horizontal at the moment of impact. Vertical bat angle is measured in degrees and provides the location of the barrel of the bat relative to the knob of the bat at impact. Vertical Bat Angle will ber zero when the barrel of the bat and the knob are parellel to the ground. Vertical Bat Angle will be negative when the barrel of the bat is below the knob og the bat at impact.

Plane

Youth: 20-80

High School: 20-80

College: 20-80

Measures the percentage of your swing where the bat is on swing plane. Your vertical bat angle at contact establishes the plane for the swing. Plane is a great indicator for making more consistent contact on the barrel of the bat.

Rotation

Youth: 20-80

High School: 20-80

College: 20-80

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 consistent contact on the barrel of the bat. 

Connection

Youth: 20-80

High School: 20-80

College: 20-80

Measures the relationship between your body tilt and vertical bat angle at impact. Maintaining good connection (90 degrees) for all pitch locations as an indicator of dynamic adjustability.

On Plane Effiecency

Youth: 70-100%

High School: 70-100%

College: 70-100%

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.
