Launch angle measures the vertical angle at which the ball comes off the bat. A launch angle of 0° is a flat line drive, positive angles go upward (fly balls), and negative angles go downward (hard grounders). The "launch angle revolution" changed modern baseball by demonstrating that slightly elevated balls produce far more damage.

The sweet spot for home runs is roughly 25–35 degrees at high exit velocity (95+ mph). This is what Statcast calls the "barrel" zone. But for overall production, the ideal average launch angle is around 12–20 degrees — high enough to generate line drives and fly balls, low enough to avoid lazy popups.

On Baseball Nut, the Zones tab on player pages shows a scatter plot of every batted ball by exit velocity and launch angle, with the barrel zone highlighted. This lets you see at a glance whether a hitter is making the right kind of contact — high-EV balls in the barrel zone are the foundation of elite offensive production.

What is a good LA?

Launch angle combines with exit velocity to determine expected outcomes (xBA, xSLG, xwOBA) that power xNUT. The optimal home-run zone is roughly 25–35 degrees at 95+ mph — the barrel zone.
