Pitcher Notes - 2020


Pitcher Notes


This is an article I like to call pitcher notes. Throughout the offseason (especially a very long one) I have been tweeting out any interesting facts I have come across. Below I have gathered most of them, 60 to be exact.


All of them are about a different pitcher and might convince you to dive deeper into a certain player. That’s the purpose of doing an exercise like this one throughout the offseason. Finding stats about pitchers others might not have can lead you to find regression or progression in a player others might not see.


  1. Gerrit Cole - Gerrit Cole had the most swing strikes when throwing a four-seam fastball at the top of the zone. He had 134 of them. The next closest was Jake Odorizzi with 94.
