BP: Moonshot: The Analytic Value of the Crack of the Bat

What’s the frequency, Robert?

I collected several games worth of audio, saving individual audio files for each contact event, and noting the result of that contact in broad terms (fly out, groundout, home run, etc.).

The result of that work was a small sample (5-10) of each event variety…

 

 

the prospects for analysis with this kind of data are broad and interesting. Because the sound off the bat is related to the bat/ball collision—specifically, where on the bat the collision occurred and how hard it was—we can begin to investigate questions about quality of contact.

I have nothing to add to this other than the sound off Bryce Harper's bat when he homered last week stood out to me so much that I had to watch the homer three more times.

Loudest I ever heard was a Jason Bay HR in KC.

This could be an interesting tool for scouting purposes, as it's a potentially less biased way to measure effective contact than the outcome of the play.

Has that one landed yet?

Mike Piazza off of Randy Johnson is one I remember. Lotta power there.

Lots of interesting stuff here, but as he admits, he has barely grazed the surface, even with the data he has. At the moment he is only looking for the peak frequency, but the shape of the spectrum is also giving us information. A chemo-metric approach similar to how chemical and material analysis is done in optical and mass spectroscopy would probably be very good at predicting the outcome based on the sound.

this at least has the possibility of being a good tool for partially separating luck from skill. As opposed to measuring hitters on outcome, one could measure on how well the ball is struck as a function of pitch type etc. Looks like a fun project. Automating the hit sound with batted ball information would be crucial though.
