In-Season QBaB check-in

Our Quality of Batted Balls (QBaB) metric, which debuted in the 2022 Baseball Forecaster, boils down the Statcast measures of exit velocity and launch angle to a simple three-digit code for every hitter. The original research from Arik Florimonte can be found here, and QBaB's A-F grade thresholds for exit velocity, launch angle, and launch angle tightness are shown below:

In 2021, Arik looked at how quickly QBaB scores for exit velocity became meaningful and found that for any sample size, a QBaB “A” for Exit Velocity (EV) is correlated with improved QBaB scores over the next 25 Batted balls (1-2 weeks), an "F" portends worse results, and a QBaB EV score of over 100 batted balls is an excellent indicator of upcoming EV.
