Sausage is the code word for "sharing my lab notes". Dan broke down pitches by type and location a couple weeks ago, and piqued my curiosity a bit.
I thought the slices and counts could be used, in part, to look at things like "who is the most aggressive pitcher on an 0-2 count?". There can be a few meanings/dimensions of aggressive pitching, but one is plate location. Here's a refresher on the slice concept.
Taking all pitches within the top/bottom of the hitter's zone (based on the average values for each hitter established by PITCHf/x operators), and classifying them by position:
The darker are in the middle is "Fat", the solid areas flanking it are "Sides", then "Edges" (now off the plate) followed by "Off" and "Wide". Fat is 8 inches wide, the rest are 4 inches. Part of "Edges" is actually the last inch of the plate (not shown in the diagram).
From there, I break the non-Fat out as In or Out. I also combine the fat with the inner "side" bit for FatIns. Curious, at the moment, about 0-2 pitches, I picked all pitchers with at least 100 of the in the PITCHf/x database, sorted it a few different ways, and found a few interesting pitchers, all outliers/extremes.
Wandy works the inner half a lot
Wakefield is not flipping you off, he just floats the knuckler over the middle.
Mo will work both sides of the plate, but not the middle - very cool.
Not Magic Wandy, The Professor stays away.
Santana works more inside relative to outside than anyone else.
Dustin Moseley is the anti-Wakefield - never down the pipe.
And, sorry, Huston is a one-way Street.
