Optimal Launch Speed and Angle for Extra Base Hits

New, comments


Where do extra base hits come from? The goal here is to show the gap between SLGCON and BABIP, along with their general trends, along two parameters: the initial speed and the launch angle of a batted ball.  Data is from the April HITf/x sample.

Sob-ip_medium

Launch-ip_medium

Let's split that last one up, at the 90mph mark (that's too low, as you can see below).

Sob-vert-speed_medium

Digest those. Next time around, I'll isolate velocity by direction (xyz) instead of giving you the overall speed.
