Statcast Lab: Swing Model
In this blog post, we discussed angular and linear speeds. And more specifically, the different linear speeds along any point on the bat.
In this blog post, we discussed how much we can Perfectly Square Up on a ball, along any point on the bat.
All that is left to do is merge the two concepts: the swing speed of the bat, and how perfectly you square up on the ball, will lead to the launch speed of the ball. (Small note: while I am using Perfectly Squared Up, behind the scenes, I am using the "collision efficiency".)
And this is how that model looks (click to embiggen):
While the maximum collision efficiency happens at around the 6 to 8 inch mark, the (linear) speed of the bat continually declines as you move away from the head of the bat. And so, the launch speed will end up maxing out at around the 6 inch mark.
