Here Are Baseball’s Most-Changed Hitters
The other day, I wrote about Corey Dickerson, and how, since he’s joined the Pirates, he’s all but stopped striking out. I went through and tried to identify changes he’s made. This has become a fairly routine writing process, looking at changes in the numbers and then going to the video. I realize I write more about players who are becoming good, or who are becoming bad, than I do about players who are still good, or who are still bad. Players who stay the same are old news. I’m biased to look for players doing something different, and in that regard I’m not alone.
Players who change are interesting. Players who don’t change are interesting, too, but those players are just out there, acknowledged and understood. When players start making adjustments, or when opponents start making adjustments to them, it’s like you’ve got a mystery box, and you just want to know what’s in it. What is the new player going to be? Has he become truly better, or truly worse? Players become moving targets, and if nothing else, we can stand to learn from whatever happens.
I guess I don’t need to justify this. I think many of us are in the same boat. We want to know who’s changing, and how. I’ve run some math. This post will have a big table in it.
