Exit velocity is the speed of the ball off a player’s bat after contact.
This is measured by a Doppler radar gun that sits behind home plate. The speed of the ball is displayed in miles per hour (MPH).
Why is exit velocity important?
Exit velocity can be a good indicator of how hard a player can hit the ball. It has also been shown to be a better predictor of future power than past home run totals.
How do you calculate exit velocity?
Exit velocity is calculated using the following formulas:
Exit Velocity = (MPH / 5) * (1 + (0.9 * 1B + 0.75 * 2B + 0.7 * 3B + 0.65 * HR))
