Instead of the usual performance statistics like wOBA and OPS, let’s look at some more fundamental measures. Definitions of each measure follow:
- Swing Efficiency is balls put in play divided by swings. It does not address whether balls put in play were hits or outs. The data was from Baseball Reference.
- Exit Velocity is the speed at which the ball leave the bat. The average exit velocities were from a Baseball Savant search which excluded bunted balls.
- Hard Hit % is batted balls with exit velocity of at least 95 MPH divided by batted balls.
