Putting Romero Back Together
Ok so it turns out I do have to go back to Romero, because although the thing that automatically detects the type of pitch is getting better, they are way off for Romero. Here’s the movement on his pitches and what the machine called them:
So the things it calls sliders are moving in two directions and at two different speeds, then there are some curveballs in the exact same place…you get the idea.
What Romero is actually throwing is this:
- A 92 mph fastball that sinks — a real 4 seam fastball is up at 9-10 horizontally, Romero’s averages about 4 inches below that.
- A 2-seamer/sinker — There’s no clear line between it and his fastball, but the ones with the most dip are about 4 mph slower and sink six inches.
- A cutter — Significantly slower and thrown only to righties.
- A change — Hmmm…I forgot to label this one. I think it was a distinct pitch. Also only thrown to righties, but with more bend and down at 80-81. Only four of them all night so hard to tell.
- A decent slider with some side-to-side variation.
- A huge breaking ball that was very consistent.
And now this just gets hideous, but if you squint your eyes at that following chart that tells you what actually happened to these pitches, here’s what you get:
- His breaking pitches were mostly balls. On the other hand, there were a few swinging strikes and nobody made contact with one all night.
- His groundouts all came on a combination of his sinker, cutter, and his fastballs that sunk so much they were pretty much sinkers.
- All the hits against him came against his fastball. Especially the ones that didn’t sink so much. Duh.
