Baseball IQ Weekly Recap: Last Day of the Season Edition
The season ends today. That was quick! I’ll keep these updates coming in their current form through the end of the playoffs. I’m going to slow down publishing during the offseason, but should still have some larger analysis/research pieces coming out, though at a lower cadence since those take more time to code up and write about.
On the topic of baseball research, I’ll be sharing my previously-promised study of batter streakiness in the next couple days. I think I’ll share an explainer about park factors after that. If there are any other sabermetric topics you’d be interested in hearing about, let me know and I might be able to include it in my offseason programming.
As a reminder, if you’ve been enjoying these updates, please consider sharing this newsletter!
On to the weekly recap.
