At the 2021 TN Preseason ID this past weekend, our Trackman B1 portable unit was purring and spitting out advanced ball flight metrics, including exit velocities and distance for all 34 prospects.  During the pitching sessions, the Trackman unit collected critical pitch metrics, such as velocity, spin rate, TrackMan is the global leader in ball-tracking accuracy. Following a Prep Baseball Report event, all players will get unrivaled access to their performance data in the Trackman interactive app. Below we look at the TrackMan top 4 for the respective categories.

Trackman Key Terms

Exit Velocity-  this one's pretty simple but this metric measures the speed of the ball off the bat, measured in miles per hour (mph).

Distance- another simple one, this metric measures how far the ball traveled or would travel if it was not obstructed, measured in feet.

Launch Angle- measures the vertical angle of the ball as it leaves the bat. Positive numbers represent balls traveling upward off of the bat and negative numbers mean the ball is traveling downward off of the bat. 

Fly Ball %-  Percentage of fly balls hit during a given set of batted ball events. Trackman defines a fly ball as any batted ball with a launch angle between 25 degrees and 49.9 degrees

Line Drive%-  Percentage of line drives hit during a given set of batted ball events. Trackman defines a line drive as any batted ball with a launch angle between 10 degrees and 24.9 degrees.

Hard Hit%-  Percentage of batted balls with an exit velocity of 90 MPH or higher. 

 

FASTBALL VELOCITY

Fastball velocity doesn't go much deeper than just looking at the numbers and comparing them to the graphic below! Fastball velocity complements just about all of the other metrics that are measured. If you throw hard, it makes all your other pitches/metrics even better.

FASTBALL SPIN RATE

Spin rate is a measurement that if you are below average or above average, you can pitch with more room for error. On the other hand, if you are average you should try to throw in the bottom half of the zone with exceptional command. High spin fastballs profile as one that is frequently described as having "late life". Low spin fastballs tend to profile as a fastball that has heavy feel to it. Pitch movement is still dependent on spin direction of the pitch but Trackman does not have that metric displayed on profiles. 


BAUER UNITS

Bauer Units are an easier way of determining how useful the spin numbers are compared to the velocity. We can calculate this metric by taking average spin rate and dividing it by average velocity. Bauer Units are useful because we can have a case of two pitchers with the same spin numbers, ex. 2200 RPM, but one pitcher throws 90 MPH and the other throws 83 MPH. The pitcher throwing 90 MPH with 2200 spin is not as impressive as the pitcher throwing 83 MPH with the same spin. Typically, we would tell the harder throwing pitcher to throw up in the zone purely off his velocity and his high spin, but because his Bauer Units would equate to around 24 that would be only 1 unit off of average (23), therefore he would want to hammer the bottom of the zone. On the other side, the pitcher throwing 83 MPH has a Bauer Unit measurement of 26 which is incredibly impressive. This would allow him to throw up in the zone even though his velocity is not blow away type numbers because he produces above average spin with that slated velocity. 

 

FASTBALL INDUCED VERTICAL BREAK

As far as deception and importance goes, fast induced vertical break (IVB) may be the most important. Induced vertical break is not what is sounds. IVB simply means the pitch is "breaking" upward from the average level a pitch falls from release to home plate. This is a stat that you want to stay away from being average at. Fortunately, this can be tweaked slightly depending on release height. To put it simply, the higher number =  more "rise" the pitch has compared to average. Lower number = more depth the pitch has to it. 

CURVEBALL SPIN RATE

Spin rate on curveballs is pretty simple: higher spin = nastier stuff. There are some ways to manipulate spin numbers slightly but for the most part spin is spin. At the moment, there are no well known ways to change your spin in a big way. Spin not only dictates how sharp your curveball is, but it can also aid in keeping hitters honest by having similar rotation matching that of your fastball.
