About Ball Speed Radars

The multi-functionality of ball speed radar guns (as distinguished from bat speed radars) makes them an essential tool for any coach, parent, or player. Although the most common use for ball speed radar guns comes in the pitching cage, they can also measure and track batted ball exit velocity (EV).

Measuring Ball Exit Speed (or Velocity (EV)) Off a Tee

“The Ball Coach™ radar has a lot of technology specifically designed to pick up the speed of the ball as it leaves the bat. This gives you the only direct measure of the power of a hit. This is often referred to as Exit Velocity or sometimes referred to as Ball Exit Speed. The Ball Coach radar can measure the Exit Velocity in batting practice, from off a tee, from soft-toss, or with live pitching. If you are using it with live pitching from behind the batter you will get the speed of the incoming pitch and the Exit Velocity off the bat as long as it is a well-hit ball with the Exit Speed faster than the incoming pitch.” (Ball Coach Radar, 2019)

Here is how to measure EV off a tee:

  • The person holding the radar gun sits behind the tee to gun the ball’s velocity going out. The radar gun is level with the ball on the tee.
  • Set the tee in the inner or outer contact zone, and inside, middle, outside, high or low hitting zone; just be consistent each swing.
  • Only record line drives; the radar must be level with ball flight to avoid angle errors.
  • Start the gun when the stride foot lands. The hitter uses a good ball and the bat they would use in a game, so the variables are always the same.
  • Count the speed on five line drives. Calculate the average and peak exit velocity (highest achieved). For future comparison, record the date, the contact and hitting zone tested, and the average and peak speeds.


Measuring Ball Exit Speed (or Velocity (EV)) with a Pitched Ball

A pitched ball introduces numerous variables that affect ball exit speed. For the data to be as reliable as possible, follow these tips:

  • If the radar is positioned behind the hitter with a net separating, the radar reports the pitched ball’s speed or the ball’s speed off the bat, whichever is greater. Some radars may even pick up the speed of the bat.
  • To lessen confusion, another method is to position the radar six feet in the air behind a net located 15 feet from the hitter (image above).
  • For comparability, whether the ball is thrown underhand or overhand, or a pitching machine is used, throws are the same speed and use the same type of ball during each measurement.
  • Ask the hitter for five line drives where the radar displays a speed faster than the pitch’s speed. Because of cosine errors, ground balls and fly balls do not read accurately on the radar gun.
  • Calculate the average and peak exit velocity (highest achieved) for the five solid hits into the net. For future comparison, record the date, the hitting zone tested (inside, middle, outside, high, low, or mixed), and the average and peak speeds.


Tracking Ball Exit Speed

During high school, Building Rome Series recommends measuring and tracking not only ball exit speed, but also the following analytics/metrics for players serious about playing in college:

  • Average and peak overall bat speed.
  • Average and peak early bat speed.
  • Average time to contact.
  • Forward movement distance during the approach.
  • Subsets of QAB% (Quality At-Bats).
  • Average and peak exit velocity.
  • Average attack angle.
  • Average launch angle.
  • Slow-motion videos of the hitter’s baseline swing over time.


Ball Exit Speed (or Velocity (EV)) by Age

 Here are the ranges of exceptional average ball exit velocity by age:

  • Little League Baseball (45-65 mph).
  • Middle School baseball(50-70 mph).
  • High School baseball(60-80 mph).
  • College baseball(70-90 mph).
  • Pro baseball (80-100 using wood).
  • Little League Softball (40-60 mph).
  • Middle School softball (45-65 mph).
  • High School softball (55-75 mph).
  • College softball (60 – 80 mph).
