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.

  2. Jacob deGrom - Jacob deGrom was the only pitcher who was top 10 in K/9, HR/9, FIP, and ERA.

  3. Lance Lynn - Lance Lynn threw his cutter 560 times and his curveball 325 times. In the 885 times he threw those pitches he didn't allow a single barrel. Both produced a 0.0 Barrel%.

  4. Max Scherzer - Max Scherzer’s insane slider: 48.0 O-Swing%, 46.6 Zone%, 26.6 SwStr%, 22.5 pVAL, 4 wRC+, and 0 homeruns.

  5. Justin Verlander - Verlander was third in the league when it came to producing a swinging strike on breaking balls outside of the zone.

  6. Charlie Morton - The pitcher who had the most swing and misses using a curveball while in a 2 strike count was Charlie Morton. He had 106 of them. The next closest was Domingo German with 77.

  7. Stephen Strasburg - Stephen Strasburg had the most swing and misses when throwing a curveball at the bottom of the zone with 67.

  8. Zack Greinke - Zack Greinke’s Slow Curve/Eephus: Thrown 62 times with a .000 Avg against, .000 ISO, -82 wRC+, 17.7 SwStr%, and 54.3 O-Swing%.

  9. Walker Buehler - Walker Buehler’s knuckle-curve lead the league in RPM’s with 2972. He also didn’t let up a single barrel on his fastball in the last two months of baseball.
