Carlos Carrasco’s Change Doesn’t Really Have a Comp
I’m back again to close out your week by talking about pitch comps. I’ve talked about pitch comps a lot lately, looking at Henderson Alvarez, and Mariano Rivera, and Cole Hamels, and so on. Pitch comps love Marcus Stroman. Not coincidentally, I also love Marcus Stroman, but this is going to be about a different guy — this is focusing on Carlos Carrasco. And while I’ve written about Carrasco already in the recent past, I want to add something to that. Carlos Carrasco throws a changeup. No one else really throws Carlos Carrasco’s changeup.
To quickly review the methodology, I use the Baseball Prospectus PITCHf/x leaderboards and look at velocity, horizontal movement, and vertical movement. For this, I looked at right-handed starting pitchers who, last year, threw at least 50 changeups, according to the page. For each of the three categories, I calculated the z-score difference between a given number and Carrasco’s changeup’s number. Then I simply added up the three absolute values, yielding a comp rating. That’s all the boring stuff. Below is the more interesting stuff.
