This Week I Learned:
Harry learns that “bullpenning” is a thing, sort of, maybe, kind of. (h/t Matt Trueblood)
Kendall learns to make adjustments in parenting, just like hitters like Mike Trout have had to make adjustments to high fastballs. (h/t to Jeff Sullivan)
We sat down with Rob Arthur, Ben Diamond, Greg Matthews, and Travis Sawchik to talk about the MLB playoffs. We touched on playoff formats (past, present, and future?) and then moved on to talk about roster construction and optimization for the playoffs. After that, Harry and Kendall talk about the things they learned this week.
This week Harry and Kendall discuss pitcher similarity scores. Where did they come from? What are they? What can they be used for? And what might they evolve into. This week Kendall learned a little about Ted Williams, and Harry learned something from Neil deGrasse Tyson.
With the news of Shohei Ohtani’s imminent posting from the NPB, this episode we talk with Sung Min Kim from the Sporting News about the posting system as well as a closer look at Ohtani. Harry and Kendall then discuss the precedence of two-way players in the Major Leagues and talk about what they’ve learned this week.
This week Harry and Kendall welcome Dan Brooks from Brooks Baseball and Russell Carleton from Baseball Prospectus. We talk with Dan and Russell about how baseball relates to their professional field of study, psychology. Russell has a new book coming out, called “The Shift”, which is available for pre-order. To steal a play from Russell’s playbook, we command you to pre-order it.
This is the first in a new recurring series called Stats and Storytellers. We’re excited to welcome Jonah Keri as our first guest.
