On August 20th NOVA Premier and PBR VA/DC held a Scout Day at Dominion High School in Sterling, VA. There were 25 players in attendance for the event. During the event we compiled swing data and metrics from each player using our Blast Motion sensors. Below are some players who stood out on Trackman.

 

Top Fastball Velocity

 

 

Top Fastball Spin Rate

The average spin rate on a Major League fastball is 2250-2350 RPMs. MLB fastballs with high spin tend to be thrown up in the zone because they appear to rise to hitters, causing the hitter to swing under them. Heavy sink fastballs have spin rates below 1800 and are thrown down in the zone to take advantage of that.

 

Top Breaking Ball Spin Rate

The average spin rate on a Major League curveball is 2500-2600 RPMs and a slider is 2400-2500 RPM. Elite MLB breaking balls spin at over 3000 RPMs.

Top Live Exit Velocity

Hitters exit velocities were measured during their BP round, these are the top exit velocities measured off the bat.

 

 

Farthest Hit Ball

Trackman calculates the estimated distance that a batted ball will travel based on exit velocity and launch angle of each batted ball.
